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][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][esm].
In Node.js (version 14.14+, 16.0+), install with [npm][]:

``sh
npm install space-separated-tokens
`

In Deno with [esm.sh][esmsh]:

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

In browsers with [esm.sh][esmsh]:

`html

`

Use

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

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

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

API

This package exports the identifiers parse and stringify.
There is no default export.

$3

Parse space-separated tokens (string) to an array of strings
(Array), according to the [WHATWG spec][spec].

$3

Serialize an array of strings or numbers (Array) to
space-separated tokens (string).

> 👉 Note: it’s not possible to specify empty or whitespace only values.

Types

This package is fully typed with [TypeScript][].
It exports no additional types.

Compatibility

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.
