vfile utility to count messages per category (fatal, warn, info, etc).

Contents

What is this?

This tiny package gives you stats about messages in files.

When should I use this?

This is really tiny, you could do it yourself, but this is useful as a building block.

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install vfile-statistics

In Deno with esm.sh:

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

In browsers with esm.sh:

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

Use

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

const file = new VFile({path: '~/example.md'})

file.message('This could be better')
file.message('That could be better')

try {
  file.fail('This is terribly wrong')
} catch {}

file.info('This is perfect')

console.log(statistics(file))

Yields:

{fatal: 1, nonfatal: 3, warn: 2, info: 1, total: 4}
