Parse and stringify comma-separated tokens.
This is a tiny package that can parse and stringify comma-separated tokens, as used for example in the HTML accept
attribute, according to the WHATWG spec.
This package is rather niche, it’s low-level and particularly useful when working with hast.
This package is ESM only. In Node.js (version 14.14+, 16.0+), install with npm:
npm install comma-separated-tokens
In Deno with esm.sh
:
import {parse, stringify} from 'https://esm.sh/comma-separated-tokens@2'
In browsers with esm.sh
:
<script type="module"> import {parse, stringify} from 'https://esm.sh/comma-separated-tokens@2?bundle' </script>
import {parse, stringify} from 'comma-separated-tokens' parse(' a ,b,,d d ') //=> ['a', 'b', '', 'd d'] stringify(['a', 'b', '', 'd d']) //=> 'a, b, , d d'
This package exports the identifier parse
and stringify
. There is no default export.
Parse commma-separated tokens (string
) to an array of strings (Array<string>

This package is at least compatible with all maintained versions of Node.js. As of now, that is Node.js 14.14+ and 16.0+. It also works in Deno and modern browsers.
