vfile utility to sort messages.


What is this?

This is a small package to sort the list of messages. It first sorts by line/column: earlier messages come first. When two messages occurr at the same place, sorts fatal error before warnings, before info messages. Finally, it sorts using localeCompare on source, ruleId, or finally reason.

When should I use this?

You can use this right before a reporter is used to give humans a coherent report.


This package is ESM only. In Node.js (version 12.20+, 14.14+, 16.0+, or 18.0+), install with npm:

npm install vfile-sort

In Deno with esm.sh:

import {sort} from 'https://esm.sh/vfile-sort@3'

In browsers with esm.sh:

<script type="module">
  import {sort} from 'https://esm.sh/vfile-sort@3?bundle'


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

const file = VFile()

file.message('Error!', {line: 3, column: 1})
file.message('Another!', {line: 2, column: 2})


console.log(file.messages.map(d => String(d)))
// => ['2:2: Another!', '3:1: Error!']


This package exports the identifier sort. There is no default export.
