Improve `buffer: false` option with IPC #1094

ehmicky · 2024-05-24T18:19:59Z

This PR is a continuation of #1092.

It improves the behavior of buffer: false with IPC, but in a simpler way than implemented in #1092.

It also adds more code comments explaining the logic on how Node.js buffers IPC messages, and how Execa differs from that default behavior.

Finally, this PR adds more tests related to that logic.

| datasource | package | from | to | | ---------- | ------- | ----- | ----- | | npm | execa | 5.1.1 | 9.3.1 | ## [v9.3.1](https://github.com/sindresorhus/execa/compare/v9.3.0...0a51f7cbef53e7290a3604e585e1b2e61da37367) ## [v9.3.0](https://github.com/sindresorhus/execa/releases/tag/v9.3.0) #### Features - The [`verbose`](docs/api.md#optionsverbose) option can now be [a function](docs/api.md#verbose-function) to [customize logging](docs/debugging.md#custom-logging). ([#1130](https://github.com/sindresorhus/execa/issues/1130)) ## [v9.2.0](https://github.com/sindresorhus/execa/releases/tag/v9.2.0) This release includes a [new set of methods](docs/ipc.md) to exchange messages between the current process and a Node.js subprocess, also known as "IPC". This allows [passing](docs/input.md#any-input-type) and [returning](docs/output.md#any-output-type) almost any message type to/from a Node.js subprocess. Also, [debugging](docs/ipc.md#debugging) IPC is now much easier. Moreover, a new [`gracefulCancel`](docs/api.md#optionsgracefulcancel) option has also been added to [terminate a subprocess gracefully](docs/termination.md#graceful-termination). For a deeper dive-in, please check and share the [release post](https://medium.com/@ehmicky/ipc-made-easy-with-execa-9-2-939c6a358731)! Thanks [@iiroj](https://github.com/iiroj) for your contribution, [@SimonSiefke](https://github.com/SimonSiefke) and [@adymorz](https://github.com/adymorz) for reporting the bugs fixed in this release, and [@karlhorky](https://github.com/karlhorky) for improving the documentation! #### Deprecations - Passing `'ipc'` to the [`stdio`](docs/api.md#optionsstdio) option has been deprecated. It will be removed in the next major release. Instead, the [`ipc: true`](docs/api.md#optionsipc) option should be used. ([#1056](https://github.com/sindresorhus/execa/issues/1056)) ```diff - await execa('npm', ['run', 'build'], {stdio: ['pipe', 'pipe', 'pipe', 'ipc']}); + await execa('npm', ['run', 'build'], {ipc: true}); ``` - The [`execaCommand()`](https://github.com/sindresorhus/execa/blob/v9.1.0/docs/api.md#execacommandcommand-options) method has been deprecated. It will be removed in the next major release. If most cases, the [template string syntax](docs/execution.md#template-string-syntax) should be used instead. ```diff - import {execaCommand} from 'execa'; + import {execa} from 'execa'; - await execaCommand('npm run build'); + await execa`npm run build`; const taskName = 'build'; - await execaCommand(`npm run ${taskName}`); + await execa`npm run ${taskName}`; const commandArguments = ['run', 'task with space']; await execa`npm ${commandArguments}`; ``` If the file and/or multiple arguments are supplied as a single string, [parseCommandString(command)](https://github.com/sindresorhus/execa/blob/main/docs/api.md#parsecommandstringcommand) can split that string into an array. [More info.](docs/escaping.md) ([#1054](https://github.com/sindresorhus/execa/issues/1054)) ```diff - import {execaCommand} from 'execa'; + import {execa, parseCommandString} from 'execa'; const commandString = 'npm run task'; - await execaCommand(commandString); + const commandArray = parseCommandString(commandString); // ['npm', 'run', 'task'] + await execa`${commandArray}`; // Or alternatively: const [file, ...commandArguments] = commandArray; await execa(file, commandArguments); ``` #### Features - Add [`gracefulCancel`](docs/api.md#optionsgracefulcancel) option and [`getCancelSignal()`](docs/api.md#getcancelsignal) method to [terminate a subprocess gracefully](docs/termination.md#graceful-termination). [`error.isGracefullyCanceled`](docs/api.md#errorisgracefullycanceled) was also added. ([#1109](https://github.com/sindresorhus/execa/issues/1109)) - Add [`error.isForcefullyTerminated`](docs/api.md#errorisforcefullyterminated). It is `true` when the subprocess was terminated by the [`forceKillAfterDelay`](docs/api.md#optionsforcekillafterdelay) option.

[`subprocess.getEachMessage()`](docs/api.md#subprocessgeteachmessagegeteachmessageoptions) listens to multiple messages. - The subprocess uses [`sendMessage(message)`](docs/api.md#sendmessagemessage-sendmessageoptions), [`getOneMessage()`](docs/api.md#getonemessagegetonemessageoptions) and [`getEachMessage()`](docs/api.md#geteachmessagegeteachmessageoptions) instead. Those are the same methods, but imported directly from the `'execa'` module. - The [`ipcInput`](docs/ipc.md#send-an-initial-message) option sends an IPC message from the current process to the subprocess as it starts. This enables [passing almost any input type](docs/input.md#any-input-type) to a Node.js subprocess. ([#1068](https://github.com/sindresorhus/execa/issues/1068)) - The [`result.ipcOutput`](docs/ipc.md#retrieve-all-messages) array contains all the IPC messages sent by the subprocess to the current process. This enables [returning almost any output type](docs/output.md#any-output-type) from a Node.js subprocess. ([#1067](https://github.com/sindresorhus/execa/issues/1067), [#1071](https://github.com/sindresorhus/execa/issues/1071), [#1075](https://github.com/sindresorhus/execa/issues/1075)) - The [error message](docs/errors.md#error-message) now [contains every IPC message](docs/ipc.md#debugging) sent by the subprocess. ([#1067](https://github.com/sindresorhus/execa/issues/1067)) - The [`verbose: 'full'`](docs/api.md#optionsverbose) option now logs every IPC message sent by the subprocess, for debugging. More info [here](docs/ipc.md#debugging) and [there](docs/output.md#stdoutstderr-specific-options). ([#1063](https://github.com/sindresorhus/execa/issues/1063)) #### Types - Add [`ExecaMethod`](docs/typescript.md#available-types), [`ExecaNodeMethod`](docs/typescript.md#available-types) and [`ExecaScriptMethod`](docs/typescript.md#available-types), [`ExecaSyncMethod`](docs/typescript.md#synchronous-execution) and [`ExecaScriptSyncMethod`](docs/typescript.md#synchronous-execution) types.

([`834e372`](https://github.com/sindresorhus/execa/commit/834e3726)) - When the [`encoding` option](docs/api.md#optionsencoding) is `'buffer'`, the output ([`result.stdout`](docs/api.md#resultstdout), [`result.stderr`](docs/api.md#resultstderr), [`result.all`](docs/api.md#resultall)) is now an [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) instead of a [`Buffer`](https://nodejs.org/api/buffer.html#class-buffer). For more information, see [this blog post](https://sindresorhus.com/blog/goodbye-nodejs-buffer). (by [@younggglcy](https://github.com/younggglcy)) ([#586](https://github.com/sindresorhus/execa/issues/586)) ```js const {stdout} = await execa('node', ['file.js'], {encoding: 'buffer'}); console.log(stdout); // This is now an Uint8Array ``` - Renamed some of the allowed values for the [`encoding`](docs/api.md#optionsencoding) option. ([#586](https://github.com/sindresorhus/execa/issues/586), [#928](https://github.com/sindresorhus/execa/issues/928)) ```diff - await execa('node', ['file.js'], {encoding: null}); + await execa('node', ['file.js'], {encoding: 'buffer'}); - await execa('node', ['file.js'], {encoding: 'utf-8'}); + await execa('node', ['file.js'], {encoding: 'utf8'}); - await execa('node', ['file.js'], {encoding: 'UTF8'}); + await execa('node', ['file.js'], {encoding: 'utf8'}); - await execa('node', ['file.js'], {encoding: 'utf-16le'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'ucs2'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'ucs-2'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'binary'}); + await execa('node', ['file.js'], {encoding: 'latin1'}); ``` - Passing a file path to `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` has been removed. Instead, a [`{file: './path'}` object](docs/output.md#file-output) should be passed to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option. ([#752](https://github.com/sindresorhus/execa/issues/752)) ```diff - await execa('node', ['file.js']).pipeStdout('output.txt'); + await execa('node', ['file.js'], {stdout: {file: 'output.txt'}}); - await execa('node', ['file.js']).pipeStderr('output.txt'); + await execa('node', ['file.js'], {stderr: {file: 'output.txt'}}); - await execa('node', ['file.js']).pipeAll('output.txt'); + await execa('node', ['file.js'], { + stdout: {file: 'output.txt'}, + stderr: {file: 'output.txt'}, +}); ``` - Passing a [writable stream](https://nodejs.org/api/stream.html#class-streamwritable) to `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` has been removed. Instead, the stream should be passed to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option. If the stream [does not have a file descriptor](docs/streams.md#file-descriptors), [`['pipe', stream]`](docs/output.md#multiple-targets) should be passed instead. ([#752](https://github.com/sindresorhus/execa/issues/752)) ```diff - await execa('node', ['file.js']).pipeStdout(stream); + await execa('node', ['file.js'], {stdout: ['pipe', stream]}); - await execa('node', ['file.js']).pipeStderr(stream); + await execa('node', ['file.js'], {stderr: ['pipe', stream]}); - await execa('node', ['file.js']).pipeAll(stream); + await execa('node', ['file.js'], { + stdout: ['pipe', stream], + stderr: ['pipe', stream], +}); ``` - The `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` methods have been renamed to [`subprocess.pipe()`](docs/api.md#subprocesspipefile-arguments-options). The command and its arguments can be passed to `subprocess.pipe()` directly, without calling `execa()` a second time. The [`from`](docs/api.md#pipeoptionsfrom) piping option can specify `'stdout'` (the default value), `'stderr'` or `'all'`. ([#757](https://github.com/sindresorhus/execa/issues/757)) ```diff - await execa('node', ['file.js']).pipeStdout(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js']); - await execa('node', ['file.js']).pipeStderr(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'stderr'}); - await execa('node', ['file.js']).pipeAll(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'all'}); ``` - Renamed the `signal` option to [`cancelSignal`](docs/api.md#optionscancelsignal). ([#880](https://github.com/sindresorhus/execa/issues/880)) ```diff - await execa('node', ['file.js'], {signal: abortController.signal}); + await execa('node', ['file.js'], {cancelSignal: abortController.signal}); ``` - Renamed `error.killed` to [`error.isTerminated`](docs/api.md#erroristerminated). ([#625](https://github.com/sindresorhus/execa/issues/625)) ```diff try { await execa('node', ['file.js']); } catch (error) { - if (error.killed) { + if (error.isTerminated) { // ... } } ``` - `subprocess.cancel()` has been removed. Please use either [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error) or the [`cancelSignal`](docs/api.md#optionscancelsignal) option instead. ([#711](https://github.com/sindresorhus/execa/issues/711)) ```diff - subprocess.cancel(); + subprocess.kill(); ``` - Renamed the `forceKillAfterTimeout` option to [`forceKillAfterDelay`](docs/api.md#optionsforcekillafterdelay). Also, it is now passed to [`execa()`](docs/api.md#execafile-arguments-options) instead of [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error). ([#714](https://github.com/sindresorhus/execa/issues/714), [#723](https://github.com/sindresorhus/execa/issues/723)) ```diff - const subprocess = execa('node', ['file.js']); - subprocess.kill('SIGTERM', {forceKillAfterTimeout: 1000}); + const subprocess = execa('node', ['file.js'], {forceKillAfterDelay: 1000}); + subprocess.kill('SIGTERM'); ``` - The [`verbose`](docs/api.md#optionsverbose) option is now a string enum instead of a boolean. `false` has been renamed to `'none'` and `true` has been renamed to [`'short'`](docs/debugging.md#short-mode). ([#884](https://github.com/sindresorhus/execa/issues/884)) ```diff - await execa('node', ['file.js'], {verbose: false}); + await execa('node', ['file.js'], {verbose: 'none'}); - await execa('node', ['file.js'], {verbose: true}); + await execa('node', ['file.js'], {verbose: 'short'}); ``` - The `execPath` option has been renamed to [`nodePath`](docs/api.md#optionsnodepath). It is now a noop unless the [`node`](docs/api.md#optionsnode) option is `true`. Also, it now works even if the [`preferLocal`](docs/api.md#optionspreferlocal) option is `false`. ([#812](https://github.com/sindresorhus/execa/issues/812), [#815](https://github.com/sindresorhus/execa/issues/815)) ```diff - await execa('node', ['file.js'], {execPath: './path/to/node'}); + await execa('node', ['file.js'], {nodePath: './path/to/node'}); ``` - The [default value](docs/ipc.md#message-type) for the [`serialization`](docs/api.md#optionsserialization) option is now [`'advanced'`](https://nodejs.org/api/child_process.html#advanced-serialization) instead of `'json'`. In particular, when calling [`subprocess.send(object)`](docs/api.md#subprocesssendmessage) with an object that contains functions or symbols, those were previously silently removed. Now this will throw an exception. ([#905](https://github.com/sindresorhus/execa/issues/905)) ```diff - subprocess.send({example: true, getExample() {}}); + subprocess.send({example: true}); ``` - If [`subprocess.stdout`](docs/api.md#subprocessstdout), [`subprocess.stderr`](docs/api.md#subprocessstderr) or [`subprocess.all`](docs/api.md#subprocessall) is manually piped, the [`.pipe()`](https://nodejs.org/api/stream.html#readablepipedestination-options) call must now happen as soon as `subprocess` is created. Otherwise, the output at the beginning of the subprocess might be missing. ([#658](https://github.com/sindresorhus/execa/issues/658), [#747](https://github.com/sindresorhus/execa/issues/747)) ```diff const subprocess = execa('node', ['file.js']); - setTimeout(() => { subprocess.stdout.pipe(process.stdout); - }, 0); ``` - Signals passed to [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error) and to the [`killSignal`](docs/api.md#optionskillsignal) option cannot be lowercase anymore. ([#1025](https://github.com/sindresorhus/execa/issues/1025)) ```diff - const subprocess = execa('node', ['file.js'], {killSignal: 'sigterm'}); + const subprocess = execa('node', ['file.js'], {killSignal: 'SIGTERM'}); - subprocess.kill('sigterm'); + subprocess.kill('SIGTERM'); ``` #### Features ##### Execution - Use the [template string syntax](docs/execution.md#template-string-syntax) with any method (including [`execa()`](docs/api.md#execacommand)), as opposed to only [`$`](docs/api.md#file-arguments-options). Conversely, `$` can now use the [regular array syntax](docs/scripts.md#template-string-syntax). ([#933](https://github.com/sindresorhus/execa/issues/933)) - A command's template string can span [multiple lines](docs/execution.md#multiple-lines). ([#843](https://github.com/sindresorhus/execa/issues/843)) - [Share options](docs/execution.md#globalshared-options) between multiple calls, or set global options, by using [`execa(options)`](docs/api#execaoptions).

Also, [debugging](docs/ipc.md#debugging) IPC is now much easier. Moreover, a new [`gracefulCancel`](docs/api.md#optionsgracefulcancel) option has also been added to [terminate a subprocess gracefully](docs/termination.md#graceful-termination).

[`subprocess.getEachMessage()`](docs/api.md#subprocessgeteachmessagegeteachmessageoptions) listens to multiple messages. - The subprocess uses [`sendMessage(message)`](docs/api.md#sendmessagemessage-sendmessageoptions), [`getOneMessage()`](docs/api.md#getonemessagegetonemessageoptions) and [`getEachMessage()`](docs/api.md#geteachmessagegeteachmessageoptions) instead. Those are the same methods, but imported directly from the `'execa'` module. - The [`ipcInput`](docs/ipc.md#send-an-initial-message) option sends an IPC message from the current process to the subprocess as it starts.

([`834e372`](https://github.com/sindresorhus/execa/commit/834e3726)) - When the [`encoding` option](docs/api.md#optionsencoding) is `'buffer'`, the output ([`result.stdout`](docs/api.md#resultstdout), [`result.stderr`](docs/api.md#resultstderr), [`result.all`](docs/api.md#resultall)) is now an [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) instead of a [`Buffer`](https://nodejs.org/api/buffer.html#class-buffer). For more information, see [this blog post](https://sindresorhus.com/blog/goodbye-nodejs-buffer). (by [@younggglcy](https://github.com/younggglcy)) ([#586](https://github.com/sindresorhus/execa/issues/586)) ```js const {stdout} = await execa('node', ['file.js'], {encoding: 'buffer'}); console.log(stdout); // This is now an Uint8Array ``` - Renamed some of the allowed values for the [`encoding`](docs/api.md#optionsencoding) option. ([#586](https://github.com/sindresorhus/execa/issues/586), [#928](https://github.com/sindresorhus/execa/issues/928)) ```diff - await execa('node', ['file.js'], {encoding: null}); + await execa('node', ['file.js'], {encoding: 'buffer'}); - await execa('node', ['file.js'], {encoding: 'utf-8'}); + await execa('node', ['file.js'], {encoding: 'utf8'}); - await execa('node', ['file.js'], {encoding: 'UTF8'}); + await execa('node', ['file.js'], {encoding: 'utf8'}); - await execa('node', ['file.js'], {encoding: 'utf-16le'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'ucs2'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'ucs-2'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'binary'}); + await execa('node', ['file.js'], {encoding: 'latin1'}); ``` - Passing a file path to `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` has been removed. Instead, a [`{file: './path'}` object](docs/output.md#file-output) should be passed to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option. ([#752](https://github.com/sindresorhus/execa/issues/752)) ```diff - await execa('node', ['file.js']).pipeStdout('output.txt'); + await execa('node', ['file.js'], {stdout: {file: 'output.txt'}}); - await execa('node', ['file.js']).pipeStderr('output.txt'); + await execa('node', ['file.js'], {stderr: {file: 'output.txt'}}); - await execa('node', ['file.js']).pipeAll('output.txt'); + await execa('node', ['file.js'], { + stdout: {file: 'output.txt'}, + stderr: {file: 'output.txt'}, +}); ``` - Passing a [writable stream](https://nodejs.org/api/stream.html#class-streamwritable) to `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` has been removed. Instead, the stream should be passed to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option. If the stream [does not have a file descriptor](docs/streams.md#file-descriptors), [`['pipe', stream]`](docs/output.md#multiple-targets) should be passed instead. ([#752](https://github.com/sindresorhus/execa/issues/752)) ```diff - await execa('node', ['file.js']).pipeStdout(stream); + await execa('node', ['file.js'], {stdout: ['pipe', stream]}); - await execa('node', ['file.js']).pipeStderr(stream); + await execa('node', ['file.js'], {stderr: ['pipe', stream]}); - await execa('node', ['file.js']).pipeAll(stream); + await execa('node', ['file.js'], { + stdout: ['pipe', stream], + stderr: ['pipe', stream], +}); ``` - The `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` methods have been renamed to [`subprocess.pipe()`](docs/api.md#subprocesspipefile-arguments-options). The command and its arguments can be passed to `subprocess.pipe()` directly, without calling `execa()` a second time. The [`from`](docs/api.md#pipeoptionsfrom) piping option can specify `'stdout'` (the default value), `'stderr'` or `'all'`. ([#757](https://github.com/sindresorhus/execa/issues/757)) ```diff - await execa('node', ['file.js']).pipeStdout(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js']); - await execa('node', ['file.js']).pipeStderr(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'stderr'}); - await execa('node', ['file.js']).pipeAll(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'all'}); ``` - Renamed the `signal` option to [`cancelSignal`](docs/api.md#optionscancelsignal). ([#880](https://github.com/sindresorhus/execa/issues/880)) ```diff - await execa('node', ['file.js'], {signal: abortController.signal}); + await execa('node', ['file.js'], {cancelSignal: abortController.signal}); ``` - Renamed `error.killed` to [`error.isTerminated`](docs/api.md#erroristerminated). ([#625](https://github.com/sindresorhus/execa/issues/625)) ```diff try { await execa('node', ['file.js']); } catch (error) { - if (error.killed) { + if (error.isTerminated) { // ... } } ``` - `subprocess.cancel()` has been removed. Please use either [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error) or the [`cancelSignal`](docs/api.md#optionscancelsignal) option instead. ([#711](https://github.com/sindresorhus/execa/issues/711)) ```diff - subprocess.cancel(); + subprocess.kill(); ``` - Renamed the `forceKillAfterTimeout` option to [`forceKillAfterDelay`](docs/api.md#optionsforcekillafterdelay). Also, it is now passed to [`execa()`](docs/api.md#execafile-arguments-options) instead of [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error). ([#714](https://github.com/sindresorhus/execa/issues/714), [#723](https://github.com/sindresorhus/execa/issues/723)) ```diff - const subprocess = execa('node', ['file.js']); - subprocess.kill('SIGTERM', {forceKillAfterTimeout: 1000}); + const subprocess = execa('node', ['file.js'], {forceKillAfterDelay: 1000}); + subprocess.kill('SIGTERM'); ``` - The [`verbose`](docs/api.md#optionsverbose) option is now a string enum instead of a boolean. `false` has been renamed to `'none'` and `true` has been renamed to [`'short'`](docs/debugging.md#short-mode). ([#884](https://github.com/sindresorhus/execa/issues/884)) ```diff - await execa('node', ['file.js'], {verbose: false}); + await execa('node', ['file.js'], {verbose: 'none'}); - await execa('node', ['file.js'], {verbose: true}); + await execa('node', ['file.js'], {verbose: 'short'}); ``` - The `execPath` option has been renamed to [`nodePath`](docs/api.md#optionsnodepath). It is now a noop unless the [`node`](docs/api.md#optionsnode) option is `true`. Also, it now works even if the [`preferLocal`](docs/api.md#optionspreferlocal) option is `false`. ([#812](https://github.com/sindresorhus/execa/issues/812), [#815](https://github.com/sindresorhus/execa/issues/815)) ```diff - await execa('node', ['file.js'], {execPath: './path/to/node'}); + await execa('node', ['file.js'], {nodePath: './path/to/node'}); ``` - The [default value](docs/ipc.md#message-type) for the [`serialization`](docs/api.md#optionsserialization) option is now [`'advanced'`](https://nodejs.org/api/child_process.html#advanced-serialization) instead of `'json'`. In particular, when calling [`subprocess.send(object)`](docs/api.md#subprocesssendmessage) with an object that contains functions or symbols, those were previously silently removed. Now this will throw an exception. ([#905](https://github.com/sindresorhus/execa/issues/905)) ```diff - subprocess.send({example: true, getExample() {}}); + subprocess.send({example: true}); ``` - If [`subprocess.stdout`](docs/api.md#subprocessstdout), [`subprocess.stderr`](docs/api.md#subprocessstderr) or [`subprocess.all`](docs/api.md#subprocessall) is manually piped, the [`.pipe()`](https://nodejs.org/api/stream.html#readablepipedestination-options) call must now happen as soon as `subprocess` is created. Otherwise, the output at the beginning of the subprocess might be missing. ([#658](https://github.com/sindresorhus/execa/issues/658), [#747](https://github.com/sindresorhus/execa/issues/747)) ```diff const subprocess = execa('node', ['file.js']); - setTimeout(() => { subprocess.stdout.pipe(process.stdout); - }, 0); ``` - Signals passed to [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error) and to the [`killSignal`](docs/api.md#optionskillsignal) option cannot be lowercase anymore. ([#1025](https://github.com/sindresorhus/execa/issues/1025)) ```diff - const subprocess = execa('node', ['file.js'], {killSignal: 'sigterm'}); + const subprocess = execa('node', ['file.js'], {killSignal: 'SIGTERM'}); - subprocess.kill('sigterm'); + subprocess.kill('SIGTERM'); ``` #### Features ##### Execution - Use the [template string syntax](docs/execution.md#template-string-syntax) with any method (including [`execa()`](docs/api.md#execacommand)), as opposed to only [`$`](docs/api.md#file-arguments-options). Conversely, `$` can now use the [regular array syntax](docs/scripts.md#template-string-syntax). ([#933](https://github.com/sindresorhus/execa/issues/933)) - A command's template string can span [multiple lines](docs/execution.md#multiple-lines). ([#843](https://github.com/sindresorhus/execa/issues/843)) - [Share options](docs/execution.md#globalshared-options) between multiple calls, or set global options, by using [`execa(options)`](docs/api#execaoptions). ([#933](https://github.com/sindresorhus/execa/issues/933), [#965](https://github.com/sindresorhus/execa/issues/965)) - Pass a file URL (as opposed to a file path string) to [`execa()`](docs/api.md#execafile-arguments-options), [`execaNode()`](docs/api.md#execanodescriptpath-arguments-options), the [`inputFile`](docs/api.md#optionsinputfile) option, the [`nodePath`](docs/api.md#optionsnodepath) option or the [`shell`](docs/api.md#optionsshell) option. ([#630](https://github.com/sindresorhus/execa/issues/630), [#631](https://github.com/sindresorhus/execa/issues/631), [#632](https://github.com/sindresorhus/execa/issues/632), [#635](https://github.com/sindresorhus/execa/issues/635)) ##### Text lines - [Split the output](docs/lines.md#simple-splitting) into text lines by using the [`lines`](docs/api.md#optionslines) option.

([#923](https://github.com/sindresorhus/execa/issues/923)) ##### Piping multiple subprocesses - Simpler syntax: pass the [command directly](docs/pipe.md#array-syntax) to [`subprocess.pipe()`](docs/api.md#subprocesspipefile-arguments-options) without calling [`execa()`](docs/api.md#execafile-arguments-options). A [template string](docs/pipe.md#template-string-syntax) can also be used. ([#840](https://github.com/sindresorhus/execa/issues/840), [#859](https://github.com/sindresorhus/execa/issues/859), [#864](https://github.com/sindresorhus/execa/issues/864)) - [Wait for both subprocesses](docs/pipe.md#result) to complete. [Error handling](docs/pipe.md#errors) has been improved too. ([#757](https://github.com/sindresorhus/execa/issues/757), [#778](https://github.com/sindresorhus/execa/issues/778), [#834](https://github.com/sindresorhus/execa/issues/834), [#854](https://github.com/sindresorhus/execa/issues/854)) - Retrieve the [result](docs/pipe.md#result) of each subprocess (not only the last one) by using [`result.pipedFrom`](docs/api.md#resultpipedfrom) and [`error.pipedFrom`](docs/api.md#resultpipedfrom). ([#834](https://github.com/sindresorhus/execa/issues/834)) - Pipe 1 or [many subprocesses](docs/pipe.md#multiple-sources-1-destination) to 1 or [many subprocesses](docs/pipe.md#1-source-multiple-destinations). ([#834](https://github.com/sindresorhus/execa/issues/834)) - Pipe subprocesses using [other file descriptors](docs/pipe.md#source-file-descriptor) than `stdin`/`stdout`/`stderr` by using the [`from`](docs/api.md#pipeoptionsfrom) and [`to`](docs/api.md#pipeoptionsto) piping options. ([#757](https://github.com/sindresorhus/execa/issues/757), [#834](https://github.com/sindresorhus/execa/issues/834), [#903](https://github.com/sindresorhus/execa/issues/903), [#920](https://github.com/sindresorhus/execa/issues/920)) - [Cancel piping](docs/pipe.md#unpipe) subprocesses by using the [`unpipeSignal`](docs/api.md#pipeoptionsunpipesignal) piping option. ([#834](https://github.com/sindresorhus/execa/issues/834), [#852](https://github.com/sindresorhus/execa/issues/852)) ##### Input/output - Pass an array with [multiple values](docs/output.md#multiple-targets) to the [`stdin`](docs/api.md#optionsstdin), [`stdout`](docs/api.md#optionsstdout) and [`stderr`](docs/api.md#optionsstderr) options.

| datasource | package | from | to | | ---------- | ------- | ----- | ----- | | npm | execa | 5.1.1 | 9.3.1 | ## [v9.3.1](https://github.com/sindresorhus/execa/compare/v9.3.0...0a51f7cbef53e7290a3604e585e1b2e61da37367) ## [v9.3.0](https://github.com/sindresorhus/execa/releases/tag/v9.3.0) #### Features - The [`verbose`](docs/api.md#optionsverbose) option can now be [a function](docs/api.md#verbose-function) to [customize logging](docs/debugging.md#custom-logging). ([#1130](https://github.com/sindresorhus/execa/issues/1130)) ## [v9.2.0](https://github.com/sindresorhus/execa/releases/tag/v9.2.0) This release includes a [new set of methods](docs/ipc.md) to exchange messages between the current process and a Node.js subprocess, also known as "IPC". This allows [passing](docs/input.md#any-input-type) and [returning](docs/output.md#any-output-type) almost any message type to/from a Node.js subprocess. Also, [debugging](docs/ipc.md#debugging) IPC is now much easier. Moreover, a new [`gracefulCancel`](docs/api.md#optionsgracefulcancel) option has also been added to [terminate a subprocess gracefully](docs/termination.md#graceful-termination). For a deeper dive-in, please check and share the [release post](https://medium.com/@ehmicky/ipc-made-easy-with-execa-9-2-939c6a358731)! Thanks [@iiroj](https://github.com/iiroj) for your contribution, [@SimonSiefke](https://github.com/SimonSiefke) and [@adymorz](https://github.com/adymorz) for reporting the bugs fixed in this release, and [@karlhorky](https://github.com/karlhorky) for improving the documentation! #### Deprecations - Passing `'ipc'` to the [`stdio`](docs/api.md#optionsstdio) option has been deprecated. It will be removed in the next major release. Instead, the [`ipc: true`](docs/api.md#optionsipc) option should be used. ([#1056](https://github.com/sindresorhus/execa/issues/1056)) ```diff - await execa('npm', ['run', 'build'], {stdio: ['pipe', 'pipe', 'pipe', 'ipc']}); + await execa('npm', ['run', 'build'], {ipc: true}); ``` - The [`execaCommand()`](https://github.com/sindresorhus/execa/blob/v9.1.0/docs/api.md#execacommandcommand-options) method has been deprecated. It will be removed in the next major release. If most cases, the [template string syntax](docs/execution.md#template-string-syntax) should be used instead. ```diff - import {execaCommand} from 'execa'; + import {execa} from 'execa'; - await execaCommand('npm run build'); + await execa`npm run build`; const taskName = 'build'; - await execaCommand(`npm run ${taskName}`); + await execa`npm run ${taskName}`; const commandArguments = ['run', 'task with space']; await execa`npm ${commandArguments}`; ``` If the file and/or multiple arguments are supplied as a single string, [parseCommandString(command)](https://github.com/sindresorhus/execa/blob/main/docs/api.md#parsecommandstringcommand) can split that string into an array. [More info.](docs/escaping.md) ([#1054](https://github.com/sindresorhus/execa/issues/1054)) ```diff - import {execaCommand} from 'execa'; + import {execa, parseCommandString} from 'execa'; const commandString = 'npm run task'; - await execaCommand(commandString); + const commandArray = parseCommandString(commandString); // ['npm', 'run', 'task'] + await execa`${commandArray}`; // Or alternatively: const [file, ...commandArguments] = commandArray; await execa(file, commandArguments); ``` #### Features - Add [`gracefulCancel`](docs/api.md#optionsgracefulcancel) option and [`getCancelSignal()`](docs/api.md#getcancelsignal) method to [terminate a subprocess gracefully](docs/termination.md#graceful-termination). [`error.isGracefullyCanceled`](docs/api.md#errorisgracefullycanceled) was also added. ([#1109](https://github.com/sindresorhus/execa/issues/1109)) - Add [`error.isForcefullyTerminated`](docs/api.md#errorisforcefullyterminated). It is `true` when the subprocess was terminated by the [`forceKillAfterDelay`](docs/api.md#optionsforcekillafterdelay) option. ([#1111](https://github.com/sindresorhus/execa/issues/1111)) - New methods to simplify exchanging messages between the current process and the subprocess.

[`subprocess.getEachMessage()`](docs/api.md#subprocessgeteachmessagegeteachmessageoptions) listens to multiple messages. - The subprocess uses [`sendMessage(message)`](docs/api.md#sendmessagemessage-sendmessageoptions), [`getOneMessage()`](docs/api.md#getonemessagegetonemessageoptions) and [`getEachMessage()`](docs/api.md#geteachmessagegeteachmessageoptions) instead. Those are the same methods, but imported directly from the `'execa'` module. - The [`ipcInput`](docs/ipc.md#send-an-initial-message) option sends an IPC message from the current process to the subprocess as it starts. This enables [passing almost any input type](docs/input.md#any-input-type) to a Node.js subprocess. ([#1068](https://github.com/sindresorhus/execa/issues/1068)) - The [`result.ipcOutput`](docs/ipc.md#retrieve-all-messages) array contains all the IPC messages sent by the subprocess to the current process. This enables [returning almost any output type](docs/output.md#any-output-type) from a Node.js subprocess. ([#1067](https://github.com/sindresorhus/execa/issues/1067), [#1071](https://github.com/sindresorhus/execa/issues/1071), [#1075](https://github.com/sindresorhus/execa/issues/1075)) - The [error message](docs/errors.md#error-message) now [contains every IPC message](docs/ipc.md#debugging) sent by the subprocess. ([#1067](https://github.com/sindresorhus/execa/issues/1067)) - The [`verbose: 'full'`](docs/api.md#optionsverbose) option now logs every IPC message sent by the subprocess, for debugging.

([#1063](https://github.com/sindresorhus/execa/issues/1063)) #### Types - Add [`ExecaMethod`](docs/typescript.md#available-types), [`ExecaNodeMethod`](docs/typescript.md#available-types) and [`ExecaScriptMethod`](docs/typescript.md#available-types), [`ExecaSyncMethod`](docs/typescript.md#synchronous-execution) and [`ExecaScriptSyncMethod`](docs/typescript.md#synchronous-execution) types.

([#1116](https://github.com/sindresorhus/execa/issues/1116)) #### Bug fixes - Fix passing a [`{file}`](docs/output.md#file-output) to both the [`stdin`](docs/api.md#optionsstdin) and the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) options.

([#586](https://github.com/sindresorhus/execa/issues/586), [#928](https://github.com/sindresorhus/execa/issues/928)) ```diff - await execa('node', ['file.js'], {encoding: null}); + await execa('node', ['file.js'], {encoding: 'buffer'}); - await execa('node', ['file.js'], {encoding: 'utf-8'}); + await execa('node', ['file.js'], {encoding: 'utf8'}); - await execa('node', ['file.js'], {encoding: 'UTF8'}); + await execa('node', ['file.js'], {encoding: 'utf8'}); - await execa('node', ['file.js'], {encoding: 'utf-16le'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'ucs2'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'ucs-2'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'binary'}); + await execa('node', ['file.js'], {encoding: 'latin1'}); ``` - Passing a file path to `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` has been removed. Instead, a [`{file: './path'}` object](docs/output.md#file-output) should be passed to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option. ([#752](https://github.com/sindresorhus/execa/issues/752)) ```diff - await execa('node', ['file.js']).pipeStdout('output.txt'); + await execa('node', ['file.js'], {stdout: {file: 'output.txt'}}); - await execa('node', ['file.js']).pipeStderr('output.txt'); + await execa('node', ['file.js'], {stderr: {file: 'output.txt'}}); - await execa('node', ['file.js']).pipeAll('output.txt'); + await execa('node', ['file.js'], { + stdout: {file: 'output.txt'}, + stderr: {file: 'output.txt'}, +}); ``` - Passing a [writable stream](https://nodejs.org/api/stream.html#class-streamwritable) to `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` has been removed. Instead, the stream should be passed to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option. If the stream [does not have a file descriptor](docs/streams.md#file-descriptors), [`['pipe', stream]`](docs/output.md#multiple-targets) should be passed instead. ([#752](https://github.com/sindresorhus/execa/issues/752)) ```diff - await execa('node', ['file.js']).pipeStdout(stream); + await execa('node', ['file.js'], {stdout: ['pipe', stream]}); - await execa('node', ['file.js']).pipeStderr(stream); + await execa('node', ['file.js'], {stderr: ['pipe', stream]}); - await execa('node', ['file.js']).pipeAll(stream); + await execa('node', ['file.js'], { + stdout: ['pipe', stream], + stderr: ['pipe', stream], +}); ``` - The `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` methods have been renamed to [`subprocess.pipe()`](docs/api.md#subprocesspipefile-arguments-options). The command and its arguments can be passed to `subprocess.pipe()` directly, without calling `execa()` a second time. The [`from`](docs/api.md#pipeoptionsfrom) piping option can specify `'stdout'` (the default value), `'stderr'` or `'all'`. ([#757](https://github.com/sindresorhus/execa/issues/757)) ```diff - await execa('node', ['file.js']).pipeStdout(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js']); - await execa('node', ['file.js']).pipeStderr(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'stderr'}); - await execa('node', ['file.js']).pipeAll(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'all'}); ``` - Renamed the `signal` option to [`cancelSignal`](docs/api.md#optionscancelsignal). ([#880](https://github.com/sindresorhus/execa/issues/880)) ```diff - await execa('node', ['file.js'], {signal: abortController.signal}); + await execa('node', ['file.js'], {cancelSignal: abortController.signal}); ``` - Renamed `error.killed` to [`error.isTerminated`](docs/api.md#erroristerminated). ([#625](https://github.com/sindresorhus/execa/issues/625)) ```diff try { await execa('node', ['file.js']); } catch (error) { - if (error.killed) { + if (error.isTerminated) { // ... } } ``` - `subprocess.cancel()` has been removed. Please use either [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error) or the [`cancelSignal`](docs/api.md#optionscancelsignal) option instead. ([#711](https://github.com/sindresorhus/execa/issues/711)) ```diff - subprocess.cancel(); + subprocess.kill(); ``` - Renamed the `forceKillAfterTimeout` option to [`forceKillAfterDelay`](docs/api.md#optionsforcekillafterdelay). Also, it is now passed to [`execa()`](docs/api.md#execafile-arguments-options) instead of [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error). ([#714](https://github.com/sindresorhus/execa/issues/714), [#723](https://github.com/sindresorhus/execa/issues/723)) ```diff - const subprocess = execa('node', ['file.js']); - subprocess.kill('SIGTERM', {forceKillAfterTimeout: 1000}); + const subprocess = execa('node', ['file.js'], {forceKillAfterDelay: 1000}); + subprocess.kill('SIGTERM'); ``` - The [`verbose`](docs/api.md#optionsverbose) option is now a string enum instead of a boolean. `false` has been renamed to `'none'` and `true` has been renamed to [`'short'`](docs/debugging.md#short-mode). ([#884](https://github.com/sindresorhus/execa/issues/884)) ```diff - await execa('node', ['file.js'], {verbose: false}); + await execa('node', ['file.js'], {verbose: 'none'}); - await execa('node', ['file.js'], {verbose: true}); + await execa('node', ['file.js'], {verbose: 'short'}); ``` - The `execPath` option has been renamed to [`nodePath`](docs/api.md#optionsnodepath). It is now a noop unless the [`node`](docs/api.md#optionsnode) option is `true`. Also, it now works even if the [`preferLocal`](docs/api.md#optionspreferlocal) option is `false`. ([#812](https://github.com/sindresorhus/execa/issues/812), [#815](https://github.com/sindresorhus/execa/issues/815)) ```diff - await execa('node', ['file.js'], {execPath: './path/to/node'}); + await execa('node', ['file.js'], {nodePath: './path/to/node'}); ``` - The [default value](docs/ipc.md#message-type) for the [`serialization`](docs/api.md#optionsserialization) option is now [`'advanced'`](https://nodejs.org/api/child_process.html#advanced-serialization) instead of `'json'`. In particular, when calling [`subprocess.send(object)`](docs/api.md#subprocesssendmessage) with an object that contains functions or symbols, those were previously silently removed. Now this will throw an exception. ([#905](https://github.com/sindresorhus/execa/issues/905)) ```diff - subprocess.send({example: true, getExample() {}}); + subprocess.send({example: true}); ``` - If [`subprocess.stdout`](docs/api.md#subprocessstdout), [`subprocess.stderr`](docs/api.md#subprocessstderr) or [`subprocess.all`](docs/api.md#subprocessall) is manually piped, the [`.pipe()`](https://nodejs.org/api/stream.html#readablepipedestination-options) call must now happen as soon as `subprocess` is created. Otherwise, the output at the beginning of the subprocess might be missing. ([#658](https://github.com/sindresorhus/execa/issues/658), [#747](https://github.com/sindresorhus/execa/issues/747)) ```diff const subprocess = execa('node', ['file.js']); - setTimeout(() => { subprocess.stdout.pipe(process.stdout); - }, 0); ``` - Signals passed to [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error) and to the [`killSignal`](docs/api.md#optionskillsignal) option cannot be lowercase anymore.

Conversely, `$` can now use the [regular array syntax](docs/scripts.md#template-string-syntax). ([#933](https://github.com/sindresorhus/execa/issues/933)) - A command's template string can span [multiple lines](docs/execution.md#multiple-lines).

([#923](https://github.com/sindresorhus/execa/issues/923)) ##### Piping multiple subprocesses - Simpler syntax: pass the [command directly](docs/pipe.md#array-syntax) to [`subprocess.pipe()`](docs/api.md#subprocesspipefile-arguments-options) without calling [`execa()`](docs/api.md#execafile-arguments-options). A [template string](docs/pipe.md#template-string-syntax) can also be used.

[Error handling](docs/pipe.md#errors) has been improved too.

([#600](https://github.com/sindresorhus/execa/issues/600)) - Fixed using both the [`maxBuffer`](docs/api.md#optionsmaxbuffer) and [`encoding`](docs/api.md#optionsencoding) options. For example, when using [`encoding: 'hex'`](docs/binary.md#encoding), `maxBuffer` will now be measured in hexadecimal characters. Also, [`error.stdout`](docs/api.md#resultstdout), [`error.stderr`](docs/api.md#resultstderr) and [`error.all`](docs/api.md#resultall) were previously not applying the `maxBuffer` option.

This allows [passing](docs/input.md#any-input-type) and [returning](docs/output.md#any-output-type) almost any message type to/from a Node.js subprocess. Also, [debugging](docs/ipc.md#debugging) IPC is now much easier. Moreover, a new [`gracefulCancel`](docs/api.md#optionsgracefulcancel) option has also been added to [terminate a subprocess gracefully](docs/termination.md#graceful-termination). For a deeper dive-in, please check and share the [release post](https://medium.com/@ehmicky/ipc-made-easy-with-execa-9-2-939c6a358731)! Thanks [@iiroj](https://github.com/iiroj) for your contribution, [@SimonSiefke](https://github.com/SimonSiefke) and [@adymorz](https://github.com/adymorz) for reporting the bugs fixed in this release, and [@karlhorky](https://github.com/karlhorky) for improving the documentation! #### Deprecations - Passing `'ipc'` to the [`stdio`](docs/api.md#optionsstdio) option has been deprecated. It will be removed in the next major release. Instead, the [`ipc: true`](docs/api.md#optionsipc) option should be used. ([#1056](https://github.com/sindresorhus/execa/issues/1056)) ```diff - await execa('npm', ['run', 'build'], {stdio: ['pipe', 'pipe', 'pipe', 'ipc']}); + await execa('npm', ['run', 'build'], {ipc: true}); ``` - The [`execaCommand()`](https://github.com/sindresorhus/execa/blob/v9.1.0/docs/api.md#execacommandcommand-options) method has been deprecated. It will be removed in the next major release. If most cases, the [template string syntax](docs/execution.md#template-string-syntax) should be used instead. ```diff - import {execaCommand} from 'execa'; + import {execa} from 'execa'; - await execaCommand('npm run build'); + await execa`npm run build`; const taskName = 'build'; - await execaCommand(`npm run ${taskName}`); + await execa`npm run ${taskName}`; const commandArguments = ['run', 'task with space']; await execa`npm ${commandArguments}`; ``` If the file and/or multiple arguments are supplied as a single string, [parseCommandString(command)](https://github.com/sindresorhus/execa/blob/main/docs/api.md#parsecommandstringcommand) can split that string into an array. [More info.](docs/escaping.md) ([#1054](https://github.com/sindresorhus/execa/issues/1054)) ```diff - import {execaCommand} from 'execa'; + import {execa, parseCommandString} from 'execa'; const commandString = 'npm run task'; - await execaCommand(commandString); + const commandArray = parseCommandString(commandString); // ['npm', 'run', 'task'] + await execa`${commandArray}`; // Or alternatively: const [file, ...commandArguments] = commandArray; await execa(file, commandArguments); ``` #### Features - Add [`gracefulCancel`](docs/api.md#optionsgracefulcancel) option and [`getCancelSignal()`](docs/api.md#getcancelsignal) method to [terminate a subprocess gracefully](docs/termination.md#graceful-termination). [`error.isGracefullyCanceled`](docs/api.md#errorisgracefullycanceled) was also added. ([#1109](https://github.com/sindresorhus/execa/issues/1109)) - Add [`error.isForcefullyTerminated`](docs/api.md#errorisforcefullyterminated). It is `true` when the subprocess was terminated by the [`forceKillAfterDelay`](docs/api.md#optionsforcekillafterdelay) option.

[`subprocess.getEachMessage()`](docs/api.md#subprocessgeteachmessagegeteachmessageoptions) listens to multiple messages. - The subprocess uses [`sendMessage(message)`](docs/api.md#sendmessagemessage-sendmessageoptions), [`getOneMessage()`](docs/api.md#getonemessagegetonemessageoptions) and [`getEachMessage()`](docs/api.md#geteachmessagegeteachmessageoptions) instead. Those are the same methods, but imported directly from the `'execa'` module. - The [`ipcInput`](docs/ipc.md#send-an-initial-message) option sends an IPC message from the current process to the subprocess as it starts. This enables [passing almost any input type](docs/input.md#any-input-type) to a Node.js subprocess. ([#1068](https://github.com/sindresorhus/execa/issues/1068)) - The [`result.ipcOutput`](docs/ipc.md#retrieve-all-messages) array contains all the IPC messages sent by the subprocess to the current process. This enables [returning almost any output type](docs/output.md#any-output-type) from a Node.js subprocess. ([#1067](https://github.com/sindresorhus/execa/issues/1067), [#1071](https://github.com/sindresorhus/execa/issues/1071), [#1075](https://github.com/sindresorhus/execa/issues/1075)) - The [error message](docs/errors.md#error-message) now [contains every IPC message](docs/ipc.md#debugging) sent by the subprocess. ([#1067](https://github.com/sindresorhus/execa/issues/1067)) - The [`verbose: 'full'`](docs/api.md#optionsverbose) option now logs every IPC message sent by the subprocess, for debugging. More info [here](docs/ipc.md#debugging) and [there](docs/output.md#stdoutstderr-specific-options). ([#1063](https://github.com/sindresorhus/execa/issues/1063)) #### Types - Add [`ExecaMethod`](docs/typescript.md#available-types), [`ExecaNodeMethod`](docs/typescript.md#available-types) and [`ExecaScriptMethod`](docs/typescript.md#available-types), [`ExecaSyncMethod`](docs/typescript.md#synchronous-execution) and [`ExecaScriptSyncMethod`](docs/typescript.md#synchronous-execution) types. ([#1066](https://github.com/sindresorhus/execa/issues/1066)) - Export the `Message` type, for [IPC](docs/ipc.md). ([#1059](https://github.com/sindresorhus/execa/issues/1059)) - Fix type of `forceKillAfterDelay: true` option. ([#1116](https://github.com/sindresorhus/execa/issues/1116)) #### Bug fixes - Fix passing a [`{file}`](docs/output.md#file-output) to both the [`stdin`](docs/api.md#optionsstdin) and the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) options. ([#1058](https://github.com/sindresorhus/execa/issues/1058)) - Fix multiple minor problems with the [`cancelSignal`](docs/termination.md#canceling) option. ([#1108](https://github.com/sindresorhus/execa/issues/1108)) - Fix accidental publishing of Vim backup files.

([`834e372`](https://github.com/sindresorhus/execa/commit/834e3726)) - When the [`encoding` option](docs/api.md#optionsencoding) is `'buffer'`, the output ([`result.stdout`](docs/api.md#resultstdout), [`result.stderr`](docs/api.md#resultstderr), [`result.all`](docs/api.md#resultall)) is now an [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) instead of a [`Buffer`](https://nodejs.org/api/buffer.html#class-buffer). For more information, see [this blog post](https://sindresorhus.com/blog/goodbye-nodejs-buffer). (by [@younggglcy](https://github.com/younggglcy)) ([#586](https://github.com/sindresorhus/execa/issues/586)) ```js const {stdout} = await execa('node', ['file.js'], {encoding: 'buffer'}); console.log(stdout); // This is now an Uint8Array ``` - Renamed some of the allowed values for the [`encoding`](docs/api.md#optionsencoding) option. ([#586](https://github.com/sindresorhus/execa/issues/586), [#928](https://github.com/sindresorhus/execa/issues/928)) ```diff - await execa('node', ['file.js'], {encoding: null}); + await execa('node', ['file.js'], {encoding: 'buffer'}); - await execa('node', ['file.js'], {encoding: 'utf-8'}); + await execa('node', ['file.js'], {encoding: 'utf8'}); - await execa('node', ['file.js'], {encoding: 'UTF8'}); + await execa('node', ['file.js'], {encoding: 'utf8'}); - await execa('node', ['file.js'], {encoding: 'utf-16le'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'ucs2'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'ucs-2'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'binary'}); + await execa('node', ['file.js'], {encoding: 'latin1'}); ``` - Passing a file path to `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` has been removed. Instead, a [`{file: './path'}` object](docs/output.md#file-output) should be passed to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option. ([#752](https://github.com/sindresorhus/execa/issues/752)) ```diff - await execa('node', ['file.js']).pipeStdout('output.txt'); + await execa('node', ['file.js'], {stdout: {file: 'output.txt'}}); - await execa('node', ['file.js']).pipeStderr('output.txt'); + await execa('node', ['file.js'], {stderr: {file: 'output.txt'}}); - await execa('node', ['file.js']).pipeAll('output.txt'); + await execa('node', ['file.js'], { + stdout: {file: 'output.txt'}, + stderr: {file: 'output.txt'}, +}); ``` - Passing a [writable stream](https://nodejs.org/api/stream.html#class-streamwritable) to `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` has been removed. Instead, the stream should be passed to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option. If the stream [does not have a file descriptor](docs/streams.md#file-descriptors), [`['pipe', stream]`](docs/output.md#multiple-targets) should be passed instead. ([#752](https://github.com/sindresorhus/execa/issues/752)) ```diff - await execa('node', ['file.js']).pipeStdout(stream); + await execa('node', ['file.js'], {stdout: ['pipe', stream]}); - await execa('node', ['file.js']).pipeStderr(stream); + await execa('node', ['file.js'], {stderr: ['pipe', stream]}); - await execa('node', ['file.js']).pipeAll(stream); + await execa('node', ['file.js'], { + stdout: ['pipe', stream], + stderr: ['pipe', stream], +}); ``` - The `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` methods have been renamed to [`subprocess.pipe()`](docs/api.md#subprocesspipefile-arguments-options). The command and its arguments can be passed to `subprocess.pipe()` directly, without calling `execa()` a second time. The [`from`](docs/api.md#pipeoptionsfrom) piping option can specify `'stdout'` (the default value), `'stderr'` or `'all'`. ([#757](https://github.com/sindresorhus/execa/issues/757)) ```diff - await execa('node', ['file.js']).pipeStdout(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js']); - await execa('node', ['file.js']).pipeStderr(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'stderr'}); - await execa('node', ['file.js']).pipeAll(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'all'}); ``` - Renamed the `signal` option to [`cancelSignal`](docs/api.md#optionscancelsignal). ([#880](https://github.com/sindresorhus/execa/issues/880)) ```diff - await execa('node', ['file.js'], {signal: abortController.signal}); + await execa('node', ['file.js'], {cancelSignal: abortController.signal}); ``` - Renamed `error.killed` to [`error.isTerminated`](docs/api.md#erroristerminated). ([#625](https://github.com/sindresorhus/execa/issues/625)) ```diff try { await execa('node', ['file.js']); } catch (error) { - if (error.killed) { + if (error.isTerminated) { // ... } } ``` - `subprocess.cancel()` has been removed. Please use either [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error) or the [`cancelSignal`](docs/api.md#optionscancelsignal) option instead.

([#609](https://github.com/sindresorhus/execa/issues/609)) - Fixed the process crashing when the [`buffer`](docs/api.md#optionsbuffer) option is `false` and [`subprocess.stdout`](docs/api.md#subprocessstdout) [errors](https://nodejs.org/api/stream.html#event-error\_1). ([#729](https://github.com/sindresorhus/execa/issues/729)) - Fixed the process crashing when passing [`'overlapped'`](docs/windows.md#asynchronous-io) to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option with [`execaSync()`](docs/api.md#execasyncfile-arguments-options). ([#949](https://github.com/sindresorhus/execa/issues/949)) - Fixed the process crashing when multiple [`'error'`](https://nodejs.org/api/child_process.html#event-error) events are emitted on the subprocess. ([#790](https://github.com/sindresorhus/execa/issues/790)) - Fixed the [`reject: false`](docs/api.md#optionsreject) option not being used when the subprocess [fails to spawn](docs/errors.md#failure-reason). ([#734](https://github.com/sindresorhus/execa/issues/734)) - Fixed [some inaccuracies](docs/errors.md#failure-reason) with [`error.isTerminated`](docs/api.md#erroristerminated). ([#625](https://github.com/sindresorhus/execa/issues/625), [#719](https://github.com/sindresorhus/execa/issues/719)) - It is now `true` when the subprocess fails due to the [`timeout`](docs/api.md#optionstimeout) option. - It is now `true` when calling [`process.kill(subprocess.pid)`](https://nodejs.org/api/process.html#processkillpid-signal), except on Windows. - It is now `false` when using [non-terminating signals](https://nodejs.org/api/child_process.html#subprocesskillsignal) such as `subprocess.kill(0)`. - Fixed missing [`error.signal`](docs/api.md#errorsignal) and [`error.signalDescription`](docs/api.md#errorsignaldescription) when the subprocess [is terminated](docs/termination.md#canceling) by the [`cancelSignal`](docs/api.md#optionscancelsignal) option. ([#724](https://github.com/sindresorhus/execa/issues/724)) - Fixed a situation where the [error](docs/api.md#execaerror) returned by an [`execa()`](docs/api.md#execafile-arguments-options) call might be modified by another `execa()` call.

([#600](https://github.com/sindresorhus/execa/issues/600)) - Fixed using both the [`maxBuffer`](docs/api.md#optionsmaxbuffer) and [`encoding`](docs/api.md#optionsencoding) options. For example, when using [`encoding: 'hex'`](docs/binary.md#encoding), `maxBuffer` will now be measured in hexadecimal characters. Also, [`error.stdout`](docs/api.md#resultstdout), [`error.stderr`](docs/api.md#resultstderr) and [`error.all`](docs/api.md#resultall) were previously not applying the `maxBuffer` option.

([#908](https://github.com/sindresorhus/execa/issues/908)) - Fixed [`subprocess.all`](docs/api.md#subprocessall) stream incorrectly being in [object mode](https://nodejs.org/api/stream.html#object-mode). ([#717](https://github.com/sindresorhus/execa/issues/717)) - Ensured [`subprocess.stdout`](docs/api.md#subprocessstdout) and [`subprocess.stderr`](docs/api.md#subprocessstderr) are properly [flushed](https://nodejs.org/api/stream.html#buffering) when the subprocess fails.

([#1130](https://github.com/sindresorhus/execa/issues/1130)) ##### [v9.2.0](https://github.com/sindresorhus/execa/releases/tag/v9.2.0) This release includes a [new set of methods](docs/ipc.md) to exchange messages between the current process and a Node.js subprocess, also known as "IPC". This allows [passing](docs/input.md#any-input-type) and [returning](docs/output.md#any-output-type) almost any message type to/from a Node.js subprocess. Also, [debugging](docs/ipc.md#debugging) IPC is now much easier. Moreover, a new [`gracefulCancel`](docs/api.md#optionsgracefulcancel) option has also been added to [terminate a subprocess gracefully](docs/termination.md#graceful-termination). For a deeper dive-in, please check and share the [release post](https://medium.com/@ehmicky/ipc-made-easy-with-execa-9-2-939c6a358731)! Thanks [@iiroj](https://github.com/iiroj) for your contribution, [@SimonSiefke](https://github.com/SimonSiefke) and [@adymorz](https://github.com/adymorz) for reporting the bugs fixed in this release, and [@karlhorky](https://github.com/karlhorky) for improving the documentation! #### Deprecations - Passing `'ipc'` to the [`stdio`](docs/api.md#optionsstdio) option has been deprecated. It will be removed in the next major release. Instead, the [`ipc: true`](docs/api.md#optionsipc) option should be used. ([#1056](https://github.com/sindresorhus/execa/issues/1056)) ```diff - await execa('npm', ['run', 'build'], {stdio: ['pipe', 'pipe', 'pipe', 'ipc']}); + await execa('npm', ['run', 'build'], {ipc: true}); ``` - The [`execaCommand()`](https://github.com/sindresorhus/execa/blob/v9.1.0/docs/api.md#execacommandcommand-options) method has been deprecated. It will be removed in the next major release. If most cases, the [template string syntax](docs/execution.md#template-string-syntax) should be used instead. ```diff - import {execaCommand} from 'execa'; + import {execa} from 'execa'; - await execaCommand('npm run build'); + await execa`npm run build`; const taskName = 'build'; - await execaCommand(`npm run ${taskName}`); + await execa`npm run ${taskName}`; const commandArguments = ['run', 'task with space']; await execa`npm ${commandArguments}`; ``` If the file and/or multiple arguments are supplied as a single string, [parseCommandString(command)](https://github.com/sindresorhus/execa/blob/main/docs/api.md#parsecommandstringcommand) can split that string into an array. [More info.](docs/escaping.md) ([#1054](https://github.com/sindresorhus/execa/issues/1054)) ```diff - import {execaCommand} from 'execa'; + import {execa, parseCommandString} from 'execa'; const commandString = 'npm run task'; - await execaCommand(commandString); + const commandArray = parseCommandString(commandString); // ['npm', 'run', 'task'] + await execa`${commandArray}`; // Or alternatively: const [file, ...commandArguments] = commandArray; await execa(file, commandArguments); ``` #### Features - Add [`gracefulCancel`](docs/api.md#optionsgracefulcancel) option and [`getCancelSignal()`](docs/api.md#getcancelsignal) method to [terminate a subprocess gracefully](docs/termination.md#graceful-termination). [`error.isGracefullyCanceled`](docs/api.md#errorisgracefullycanceled) was also added. ([#1109](https://github.com/sindresorhus/execa/issues/1109)) - Add [`error.isForcefullyTerminated`](docs/api.md#errorisforcefullyterminated). It is `true` when the subprocess was terminated by the [`forceKillAfterDelay`](docs/api.md#optionsforcekillafterdelay) option.

[`subprocess.getEachMessage()`](docs/api.md#subprocessgeteachmessagegeteachmessageoptions) listens to multiple messages. - The subprocess uses [`sendMessage(message)`](docs/api.md#sendmessagemessage-sendmessageoptions), [`getOneMessage()`](docs/api.md#getonemessagegetonemessageoptions) and [`getEachMessage()`](docs/api.md#geteachmessagegeteachmessageoptions) instead. Those are the same methods, but imported directly from the `'execa'` module. - The [`ipcInput`](docs/ipc.md#send-an-initial-message) option sends an IPC message from the current process to the subprocess as it starts. This enables [passing almost any input type](docs/input.md#any-input-type) to a Node.js subprocess. ([#1068](https://github.com/sindresorhus/execa/issues/1068)) - The [`result.ipcOutput`](docs/ipc.md#retrieve-all-messages) array contains all the IPC messages sent by the subprocess to the current process.

([`834e372`](https://github.com/sindresorhus/execa/commit/834e3726)) - When the [`encoding` option](docs/api.md#optionsencoding) is `'buffer'`, the output ([`result.stdout`](docs/api.md#resultstdout), [`result.stderr`](docs/api.md#resultstderr), [`result.all`](docs/api.md#resultall)) is now an [`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array) instead of a [`Buffer`](https://nodejs.org/api/buffer.html#class-buffer). For more information, see [this blog post](https://sindresorhus.com/blog/goodbye-nodejs-buffer). (by [@younggglcy](https://github.com/younggglcy)) ([#586](https://github.com/sindresorhus/execa/issues/586)) ```js const {stdout} = await execa('node', ['file.js'], {encoding: 'buffer'}); console.log(stdout); // This is now an Uint8Array ``` - Renamed some of the allowed values for the [`encoding`](docs/api.md#optionsencoding) option. ([#586](https://github.com/sindresorhus/execa/issues/586), [#928](https://github.com/sindresorhus/execa/issues/928)) ```diff - await execa('node', ['file.js'], {encoding: null}); + await execa('node', ['file.js'], {encoding: 'buffer'}); - await execa('node', ['file.js'], {encoding: 'utf-8'}); + await execa('node', ['file.js'], {encoding: 'utf8'}); - await execa('node', ['file.js'], {encoding: 'UTF8'}); + await execa('node', ['file.js'], {encoding: 'utf8'}); - await execa('node', ['file.js'], {encoding: 'utf-16le'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'ucs2'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'ucs-2'}); + await execa('node', ['file.js'], {encoding: 'utf16le'}); - await execa('node', ['file.js'], {encoding: 'binary'}); + await execa('node', ['file.js'], {encoding: 'latin1'}); ``` - Passing a file path to `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` has been removed. Instead, a [`{file: './path'}` object](docs/output.md#file-output) should be passed to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option. ([#752](https://github.com/sindresorhus/execa/issues/752)) ```diff - await execa('node', ['file.js']).pipeStdout('output.txt'); + await execa('node', ['file.js'], {stdout: {file: 'output.txt'}}); - await execa('node', ['file.js']).pipeStderr('output.txt'); + await execa('node', ['file.js'], {stderr: {file: 'output.txt'}}); - await execa('node', ['file.js']).pipeAll('output.txt'); + await execa('node', ['file.js'], { + stdout: {file: 'output.txt'}, + stderr: {file: 'output.txt'}, +}); ``` - Passing a [writable stream](https://nodejs.org/api/stream.html#class-streamwritable) to `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` has been removed. Instead, the stream should be passed to the [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option. If the stream [does not have a file descriptor](docs/streams.md#file-descriptors), [`['pipe', stream]`](docs/output.md#multiple-targets) should be passed instead. ([#752](https://github.com/sindresorhus/execa/issues/752)) ```diff - await execa('node', ['file.js']).pipeStdout(stream); + await execa('node', ['file.js'], {stdout: ['pipe', stream]}); - await execa('node', ['file.js']).pipeStderr(stream); + await execa('node', ['file.js'], {stderr: ['pipe', stream]}); - await execa('node', ['file.js']).pipeAll(stream); + await execa('node', ['file.js'], { + stdout: ['pipe', stream], + stderr: ['pipe', stream], +}); ``` - The `subprocess.pipeStdout()`, `subprocess.pipeStderr()` and `subprocess.pipeAll()` methods have been renamed to [`subprocess.pipe()`](docs/api.md#subprocesspipefile-arguments-options). The command and its arguments can be passed to `subprocess.pipe()` directly, without calling `execa()` a second time. The [`from`](docs/api.md#pipeoptionsfrom) piping option can specify `'stdout'` (the default value), `'stderr'` or `'all'`. ([#757](https://github.com/sindresorhus/execa/issues/757)) ```diff - await execa('node', ['file.js']).pipeStdout(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js']); - await execa('node', ['file.js']).pipeStderr(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'stderr'}); - await execa('node', ['file.js']).pipeAll(execa('node', ['other.js'])); + await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'all'}); ``` - Renamed the `signal` option to [`cancelSignal`](docs/api.md#optionscancelsignal). ([#880](https://github.com/sindresorhus/execa/issues/880)) ```diff - await execa('node', ['file.js'], {signal: abortController.signal}); + await execa('node', ['file.js'], {cancelSignal: abortController.signal}); ``` - Renamed `error.killed` to [`error.isTerminated`](docs/api.md#erroristerminated). ([#625](https://github.com/sindresorhus/execa/issues/625)) ```diff try { await execa('node', ['file.js']); } catch (error) { - if (error.killed) { + if (error.isTerminated) { // ... } } ``` - `subprocess.cancel()` has been removed. Please use either [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error) or the [`cancelSignal`](docs/api.md#optionscancelsignal) option instead. ([#711](https://github.com/sindresorhus/execa/issues/711)) ```diff - subprocess.cancel(); + subprocess.kill(); ``` - Renamed the `forceKillAfterTimeout` option to [`forceKillAfterDelay`](docs/api.md#optionsforcekillafterdelay). Also, it is now passed to [`execa()`](docs/api.md#execafile-arguments-options) instead of [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error). ([#714](https://github.com/sindresorhus/execa/issues/714), [#723](https://github.com/sindresorhus/execa/issues/723)) ```diff - const subprocess = execa('node', ['file.js']); - subprocess.kill('SIGTERM', {forceKillAfterTimeout: 1000}); + const subprocess = execa('node', ['file.js'], {forceKillAfterDelay: 1000}); + subprocess.kill('SIGTERM'); ``` - The [`verbose`](docs/api.md#optionsverbose) option is now a string enum instead of a boolean. `false` has been renamed to `'none'` and `true` has been renamed to [`'short'`](docs/debugging.md#short-mode). ([#884](https://github.com/sindresorhus/execa/issues/884)) ```diff - await execa('node', ['file.js'], {verbose: false}); + await execa('node', ['file.js'], {verbose: 'none'}); - await execa('node', ['file.js'], {verbose: true}); + await execa('node', ['file.js'], {verbose: 'short'}); ``` - The `execPath` option has been renamed to [`nodePath`](docs/api.md#optionsnodepath). It is now a noop unless the [`node`](docs/api.md#optionsnode) option is `true`. Also, it now works even if the [`preferLocal`](docs/api.md#optionspreferlocal) option is `false`. ([#812](https://github.com/sindresorhus/execa/issues/812), [#815](https://github.com/sindresorhus/execa/issues/815)) ```diff - await execa('node', ['file.js'], {execPath: './path/to/node'}); + await execa('node', ['file.js'], {nodePath: './path/to/node'}); ``` - The [default value](docs/ipc.md#message-type) for the [`serialization`](docs/api.md#optionsserialization) option is now [`'advanced'`](https://nodejs.org/api/child_process.html#advanced-serialization) instead of `'json'`. In particular, when calling [`subprocess.send(object)`](docs/api.md#subprocesssendmessage) with an object that contains functions or symbols, those were previously silently removed. Now this will throw an exception. ([#905](https://github.com/sindresorhus/execa/issues/905)) ```diff - subprocess.send({example: true, getExample() {}}); + subprocess.send({example: true}); ``` - If [`subprocess.stdout`](docs/api.md#subprocessstdout), [`subprocess.stderr`](docs/api.md#subprocessstderr) or [`subprocess.all`](docs/api.md#subprocessall) is manually piped, the [`.pipe()`](https://nodejs.org/api/stream.html#readablepipedestination-options) call must now happen as soon as `subprocess` is created. Otherwise, the output at the beginning of the subprocess might be missing. ([#658](https://github.com/sindresorhus/execa/issues/658), [#747](https://github.com/sindresorhus/execa/issues/747)) ```diff const subprocess = execa('node', ['file.js']); - setTimeout(() => { subprocess.stdout.pipe(process.stdout); - }, 0); ``` - Signals passed to [`subprocess.kill()`](docs/api.md#subprocesskillsignal-error) and to the [`killSignal`](docs/api.md#optionskillsignal) option cannot be lowercase anymore. ([#1025](https://github.com/sindresorhus/execa/issues/1025)) ```diff - const subprocess = execa('node', ['file.js'], {killSignal: 'sigterm'}); + const subprocess = execa('node', ['file.js'], {killSignal: 'SIGTERM'}); - subprocess.kill('sigterm'); + subprocess.kill('SIGTERM'); ``` #### Features ##### Execution - Use the [template string syntax](docs/execution.md#template-string-syntax) with any method (including [`execa()`](docs/api.md#execacommand)), as opposed to only [`$`](docs/api.md#file-arguments-options). Conversely, `$` can now use the [regular array syntax](docs/scripts.md#template-string-syntax). ([#933](https://github.com/sindresorhus/execa/issues/933)) - A command's template string can span [multiple lines](docs/execution.md#multiple-lines). ([#843](https://github.com/sindresorhus/execa/issues/843)) - [Share options](docs/execution.md#globalshared-options) between multiple calls, or set global options, by using [`execa(options)`](docs/api#execaoptions). ([#933](https://github.com/sindresorhus/execa/issues/933), [#965](https://github.com/sindresorhus/execa/issues/965)) - Pass a file URL (as opposed to a file path string) to [`execa()`](docs/api.md#execafile-arguments-options), [`execaNode()`](docs/api.md#execanodescriptpath-arguments-options), the [`inputFile`](docs/api.md#optionsinputfile) option, the [`nodePath`](docs/api.md#optionsnodepath) option or the [`shell`](docs/api.md#optionsshell) option. ([#630](https://github.com/sindresorhus/execa/issues/630), [#631](https://github.com/sindresorhus/execa/issues/631), [#632](https://github.com/sindresorhus/execa/issues/632), [#635](https://github.com/sindresorhus/execa/issues/635)) ##### Text lines - [Split the output](docs/lines.md#simple-splitting) into text lines by using the [`lines`](docs/api.md#optionslines) option. ([#741](https://github.com/sindresorhus/execa/issues/741), [#929](https://github.com/sindresorhus/execa/issues/929), [#931](https://github.com/sindresorhus/execa/issues/931), [#948](https://github.com/sindresorhus/execa/issues/948), [#951](https://github.com/sindresorhus/execa/issues/951), [#957](https://github.com/sindresorhus/execa/issues/957)) - Subprocess is now an [async iterable](docs/api.md#subprocesssymbolasynciterator), [iterating over the output](docs/lines.md#progressive-splitting) lines while the subprocess is running. ([#923](https://github.com/sindresorhus/execa/issues/923)) ##### Piping multiple subprocesses - Simpler syntax: pass the [command directly](docs/pipe.md#array-syntax) to [`subprocess.pipe()`](docs/api.md#subprocesspipefile-arguments-options) without calling [`execa()`](docs/api.md#execafile-arguments-options). A [template string](docs/pipe.md#template-string-syntax) can also be used. ([#840](https://github.com/sindresorhus/execa/issues/840), [#859](https://github.com/sindresorhus/execa/issues/859), [#864](https://github.com/sindresorhus/execa/issues/864)) - [Wait for both subprocesses](docs/pipe.md#result) to complete. [Error handling](docs/pipe.md#errors) has been improved too. ([#757](https://github.com/sindresorhus/execa/issues/757), [#778](https://github.com/sindresorhus/execa/issues/778), [#834](https://github.com/sindresorhus/execa/issues/834), [#854](https://github.com/sindresorhus/execa/issues/854)) - Retrieve the [result](docs/pipe.md#result) of each subprocess (not only the last one) by using [`result.pipedFrom`](docs/api.md#resultpipedfrom) and [`error.pipedFrom`](docs/api.md#resultpipedfrom). ([#834](https://github.com/sindresorhus/execa/issues/834)) - Pipe 1 or [many subprocesses](docs/pipe.md#multiple-sources-1-destination) to 1 or [many subprocesses](docs/pipe.md#1-source-multiple-destinations). ([#834](https://github.com/sindresorhus/execa/issues/834)) - Pipe subprocesses using [other file descriptors](docs/pipe.md#source-file-descriptor) than `stdin`/`stdout`/`stderr` by using the [`from`](docs/api.md#pipeoptionsfrom) and [`to`](docs/api.md#pipeoptionsto) piping options. ([#757](https://github.com/sindresorhus/execa/issues/757), [#834](https://github.com/sindresorhus/execa/issues/834), [#903](https://github.com/sindresorhus/execa/issues/903), [#920](https://github.com/sindresorhus/execa/issues/920)) - [Cancel piping](docs/pipe.md#unpipe) subprocesses by using the [`unpipeSignal`](docs/api.md#pipeoptionsunpipesignal) piping option. ([#834](https://github.com/sindresorhus/execa/issues/834), [#852](https://github.com/sindresorhus/execa/issues/852)) ##### Input/output - Pass an array with [multiple values](docs/output.md#multiple-targets) to the [`stdin`](docs/api.md#optionsstdin), [`stdout`](docs/api.md#optionsstdout) and [`stderr`](docs/api.md#optionsstderr) options. For example, [`stdout: ['inherit', 'pipe']`](docs/output.md#multiple-targets) prints the output [to the terminal](docs/output.md#terminal-output) while still [returning it](docs/output.md#stdout-and-stderr) as [`result.stdout`](docs/api.md#resultstdout). ([#643](https://github.com/sindresorhus/execa/issues/643), [#765](https://github.com/sindresorhus/execa/issues/765), [#941](https://github.com/sindresorhus/execa/issues/941), [#954](https://github.com/sindresorhus/execa/issues/954)) - Redirect the [input](docs/input.md#file-input)/[output](docs/output.md#file-output) from/to a file by passing a `{file: './path'}` object or a file URL to the [`stdin`](docs/api.md#optionsstdin), [`stdout`](docs/api.md#optionsstdout) or [`stderr`](docs/api.md#optionsstderr) option.
