space-separated-tokens

Parse and stringify space-separated tokens.

What is this?

This is a tiny package that can parse and stringify space-separated tokens, as used for example in the HTML class attribute, according to the WHATWG spec.

When should I use this?

This package is rather niche, it’s low-level and particularly useful when working with hast.

Install

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

npm install space-separated-tokens

In Deno with esm.sh:

import {parse, stringify} from 'https://esm.sh/space-separated-tokens@2'

In browsers with esm.sh:

<script type="module">
  import {parse, stringify} from 'https://esm.sh/space-separated-tokens@2?bundle'
</script>

Use

import {parse, stringify} from 'space-separated-tokens'

parse(' foo\tbar\nbaz  ')
//=> ['foo', 'bar', 'baz']

stringify(['foo', 'bar', 'baz'])
//=> 'foo bar baz'
