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. ### `parse(value)` Parse space-separated tokens (`string`) to an array of strings (`Array`), according to the [WHATWG spec][spec]. ### `stringify(values)` 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. ## Related * [`comma-separated-tokens`](https://github.com/wooorm/comma-separated-tokens) — parse/stringify comma-separated tokens * [`collapse-white-space`](https://github.com/wooorm/collapse-white-space) — replace multiple white-space characters with a single space * [`property-information`](https://github.com/wooorm/property-information) — info on HTML properties ## Contribute Yes please!
