## 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
|
||
<script type="module">
|
||
import {parse, stringify} from 'https://esm.sh/space-separated-tokens@2?bundle'
|
||
</script>
|
||
```
|
||
|
||
## 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.
|
||
|
||
### `parse(value)`
|
||
|
||
Parse space-separated tokens (`string`) to an array of strings
|
||
(`Array<string>`), according to the [WHATWG spec][spec].
|
||
|
||
### `stringify(values)`
|
||
|
||
Serialize an array of strings or numbers (`Array<string|number>`) 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.
