Retext-spell NPM

retext-spell

retext plugin to check spelling.

What is this?

This package is a unified (retext) plugin to check spelling with nspell and a dictionary.

When should I use this?

You can opt-into this plugin when you’re dealing with content that might contain spelling mistakes, and have authors that can fix that content.

Install

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

npm install retext-spell

In Deno with esm.sh:

import retextSpell from 'https://esm.sh/retext-spell@6'

In browsers with esm.sh:

<script type="module">
  import retextSpell from 'https://esm.sh/retext-spell@6?bundle'
</script>

Use

import dictionaryEn from 'dictionary-en'
import {retext} from 'retext'
import retextSpell from 'retext-spell'
import {reporter} from 'vfile-reporter'

const file = await retext()
  .use(retextSpell, {dictionary: dictionaryEn})
  .process('Some useles documeant.')

console.error(reporter(file))

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, retext-spell@^6, compatible with Node.js 16.
