jsdoc-x

Parser for outputting a Javascript object from documented code via JSDoc's explain (-X) command.

Install via NPM:

npm i jsdoc-x

Usage:

const jsdocx = require('jsdoc-x');
try {
    const docs = await jsdocx.parse('./src/**/*.js');
    console.log(docs);
} catch (err) {
    console.log(err.stack);
}

(If you like pain, .parse() method also supports a callback, instead of promises.)

See an output example here.

jsdocx.parse(options[, callback])

Executes the jsdoc -X command and parses the output into a Javascript object/array; with the specified options.

Param	Type	Description
options	Object|Array|String	Required. Either an options object or one or more source files to be processed. See details below.
callback	Function	Callback function to be executed in the following signature: `function (err, array) { ... }`. Omit this callback to return a `Promise`. Default: undefined

options

Object|Array|String - Parse options.

Option	Type	Description
files	String|Array	Required (if source is not set). One or more file/directory paths to be processed. This also accepts a Glob string or array of globs. e.g. ./src/**/*.js will produce an array of all .js files under ./src directory and sub-directories. Default: undefined
source	String	Required (if files is not set). Documented source code to be processed. If files is also set, this will be ignored. Default: undefined
config	Object	Pass a configuration object to the underlying JSDoc core. This will bypass all parser options. Default: {}
encoding	String	Encoding to be used when reading source files. Default: "utf8"
recurse	Boolean	Specifies whether to recurse into subdirectories when scanning for source files. Default: false
pedantic	Boolean	Specifies whether to treat errors as fatal errors, and treat warnings as errors. Default: false
access	String|Array	Specifies which symbols to be processed with the given access property. Possible values: "private", "protected", "public" or "all" (for all access levels). By default, all except private symbols are processed. Note that, if access is not set for a documented symbol, it will still be included, regardless of this option. Default: undefined
private	Boolean	Shorthand for enabling documentation for private access symbols. Default: false
package	String	The path to the package.json file that contains the project name, version, and other details. If set to true instead of a path string, the first package.json file found in the source paths. Default: undefined
module	Boolean	Specifies whether to include module.exports symbols. Default: true
undocumented	Boolean	Specifies whether to include undocumented symbols. Default: true
undescribed	Boolean	Specifies whether to include symbols without a description. Default: true
ignored	Boolean	Specifies whether to include symbols marked with @ignore tag. Default: true
allowUnknownTags	Boolean	Specifies whether to allow unrecognized tags. If set to false parsing will fail on unknown tags. Default: true
dictionaries	Array	Indicates the dictionaries to be used. By default, both standard JSDoc tags and Closure Compiler tags are enabled. Default: ["jsdoc", "closure"]
includePattern	String	String pattern for defining sources to be included. By default, only files ending in ".js", ".jsdoc", and ".jsx" will be processed. Default: ".+\\.js(doc|x)?$"
excludePattern	String	String pattern for defining sources to be ignored. By default, any file starting with an underscore or in a directory starting with an underscore will be ignored. Default: "(^|\\/|\\\\)_"
plugins	Array	Defines the JSDoc plugins to be used. See this guide on JSDoc plugins. Default: []
relativePath	String	When set, all symbol.meta.path values will be relative to this path. Default: undefined
predicate	Function|string	Alias: filter. This is used to filter the parsed documentation output array. If a Function is passed; it's invoked for each included symbol. e.g. function (symbol) { return symbol; } Returning a falsy value will remove the symbol from the output. Returning true will keep the original symbol. To keep the symbol and alter its contents, simply return an altered symbol object. If a RegExp string is passed, it's executed on the symbol's long name. Default: undefined
hierarchy	Boolean	Specifies whether to arrange symbols by their hierarchy. This will find and move symbols that have a memberof property to a $members property of their corresponding owners. Also the constructor symbol will be moved to a $constructor property of the ClassDeclaration symbol; if any. Default: false
sort	Boolean|String	Specifies whether to sort the documentation symbols. For alphabetic sort, set to true or "alphabetic". To group-sort set to "grouped". (Group sorting is done in the following order: by memberof, by scope, by access type, by kind, alphabetic.) To sort by only "scope" or "access" or "kind", set to corresponding string. (Sorting by kind is done in the following order: constant, package/module, namespace, class, constructor, method, property, enum, typedef, event, interface, mixin, external, other members.) Set to false to disable. Default: false
output	String|Object	Path for a JSON file to be created, containing the output documentation array. Or you can set this to an object for extra options. Default: undefined
↳output.path	String	Path for a JSON file to be created. Default: undefined
↳output.indent	Boolean|Number	Number of spaces for indentation. If set to true, 2 spaces will be used. Default: false
↳output.force	Boolean	Whether to create parent directories if they don't exist. Default: false
debug	Boolean	Specifies whether to include extra information within thrown error messages. Default: true

jsdocx.filter(docs[, options][, predicate])

Param	Type	Description
docs	Array	Required. Documentation output array.
options	Object	Filter options. See details below. Default: undefined
predicate	Function	The function invoked per iteration. Returning a falsy value will remove the symbol from the output. Returning true will keep the original symbol. To keep the symbol and alter its contents, simply return an altered symbol object. Default: undefined

options

Object - Filter options.

Option	Type	Description
access	String|Array	Specifies which symbols to be processed with the given access property. Possible values: "private", "protected", "public" or "all" (for all access levels). By default, all except private symbols are processed. Note that, if access is not set for a documented symbol, it will still be included, regardless of this option. Default: undefined
package	String	The path to the package.json file that contains the project name, version, and other details. If set to true instead of a path string, the first package.json file found in the source paths. Default: undefined
module	Boolean	Specifies whether to include module.exports symbols. Default: true
undocumented	Boolean	Specifies whether to include undocumented symbols. Default: true
undescribed	Boolean	Specifies whether to include symbols without a description. Default: true
relativePath	String	When set, all symbol.meta.path values will be relative to this path. Default: undefined
hierarchy	Boolean	Specifies whether to arrange symbols by their hierarchy. This will find and move symbols that have a memberof property to a $members property of their corresponding owners. Also the constructor symbol will be moved to a $constructor property of the ClassDeclaration symbol; if any. Default: false
sort	Boolean|String	Specifies whether to sort the documentation symbols. For alphabetic sort, set to true or "alphabetic". To additionally group by scope (static/instance) set to "grouped". Set to false to disable. Default: false

jsdocx.utils
