vfile utility to create a report.

Example screenshot of vfile-reporter


What is this?

This package create a textual report from a file showing the warnings that occurred while processing. Many CLIs of tools that process files, whether linters (such as ESLint) or bundlers (such as esbuild), have similar functionality.

When should I use this?

You can use this package whenever you want to display a report about what occurred while processing to a human.

There are other reporters that display information differently listed in vfile.


This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install vfile-reporter

In Deno with esm.sh:

import {reporter} from 'https://esm.sh/vfile-reporter@7'

In browsers with esm.sh:

<script type="module">
  import {reporter} from 'https://esm.sh/vfile-reporter@7?bundle'


Say our module example.js looks as follows:

import {VFile} from 'vfile'
import {reporter} from 'vfile-reporter'

const one = new VFile({path: 'test/fixture/1.js'})
const two = new VFile({path: 'test/fixture/2.js'})

one.message('Warning!', {line: 2, column: 4})

console.error(reporter([one, two]))

…now running node example.js yields:

  2:4  warning  Warning!

test/fixture/2.js: no issues found

⚠ 1 warning


This package exports the identifier reporter. That value is also the default export.

reporter(files[, options])

Create a report from an error, one file, or multiple files.


Configuration (optional).


Use ANSI colors in report (boolean, default: depends). The default behavior in Node.js is the check if color is supported.


Show message notes (boolean, default: false). Notes are optional, additional, long descriptions.


Do not show files without messages (boolean, default: false).


Show errors only (boolean, default: false). This does not show info and warning messages. Also sets quiet to true.


Label to use for files without file path (string, default: '<stdin>'). If one file and no defaultName is given, no name will show up in the report.


Report (string).


This package is fully typed with TypeScript. It exports the additional type Options.


Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 12.20+, 14.14+, 16.0+, and 18.0+. Our projects sometimes work with older versions, but this is not guaranteed.


Use of vfile-reporter is safe.
