# Debug | ||
|
||
Undici (and subsenquently `fetch` and `websocket`) exposes a debug statement that can be enabled by setting `NODE_DEBUG` within the environment. | ||
|
||
The flags availabile are: | ||
|
||
## `undici` | ||
|
||
This flag enables debug statements for the core undici library. | ||
|
||
```sh | ||
NODE_DEBUG=undici node script.js | ||
|
||
UNDICI 16241: connecting to nodejs.org using https:h1 | ||
UNDICI 16241: connecting to nodejs.org using https:h1 | ||
UNDICI 16241: connected to nodejs.org using https:h1 | ||
UNDICI 16241: sending request to GET https://nodejs.org// | ||
UNDICI 16241: received response to GET https://nodejs.org// - HTTP 307 | ||
UNDICI 16241: connecting to nodejs.org using https:h1 | ||
UNDICI 16241: trailers received from GET https://nodejs.org// | ||
UNDICI 16241: connected to nodejs.org using https:h1 | ||
UNDICI 16241: sending request to GET https://nodejs.org//en | ||
UNDICI 16241: received response to GET https://nodejs.org//en - HTTP 200 | ||
UNDICI 16241: trailers received from GET https://nodejs.org//en | ||
``` | ||
|
||
## `fetch` | ||
|
||
This flag enables debug statements for the `fetch` API. | ||
|
||
> **Note**: statements are pretty similar to the ones in the `undici` flag, but scoped to `fetch` | ||
```sh | ||
NODE_DEBUG=fetch node script.js | ||
|
||
FETCH 16241: connecting to nodejs.org using https:h1 | ||
FETCH 16241: connecting to nodejs.org using https:h1 | ||
FETCH 16241: connected to nodejs.org using https:h1 | ||
FETCH 16241: sending request to GET https://nodejs.org// | ||
FETCH 16241: received response to GET https://nodejs.org// - HTTP 307 | ||
FETCH 16241: connecting to nodejs.org using https:h1 | ||
FETCH 16241: trailers received from GET https://nodejs.org// | ||
FETCH 16241: connected to nodejs.org using https:h1 | ||
FETCH 16241: sending request to GET https://nodejs.org//en | ||
FETCH 16241: received response to GET https://nodejs.org//en - HTTP 200 | ||
FETCH 16241: trailers received from GET https://nodejs.org//en | ||
``` | ||
|
||
## `websocket` | ||
|
||
This flag enables debug statements for the `Websocket` API. | ||
|
||
> **Note**: statements can overlap with `UNDICI` ones if `undici` or `fetch` flag has been enabled as well. | ||
```sh | ||
NODE_DEBUG=fetch node script.js | ||
|
||
WEBSOCKET 18309: connecting to echo.websocket.org using https:h1 | ||
WEBSOCKET 18309: connected to echo.websocket.org using https:h1 | ||
WEBSOCKET 18309: sending request to GET https://echo.websocket.org// | ||
WEBSOCKET 18309: connection opened <ip_address> | ||
