What is this?
This package is a utility to check whether a hast node is a <script> that
contains or references JavaScript.
When should I use this?
You can use this package to check whether <script> elements contain or
reference JavaScript or something else.
Install
This package is ESM only. In Node.js (version 16+), install with npm:
1npm install hast-util-is-javascript
In Deno with esm.sh:
1import {isJavaScript} from 'https://esm.sh/hast-util-is-javascript@3'
In browsers with esm.sh:
1<script type="module"> 2 import {isJavaScript} from 'https://esm.sh/hast-util-is-javascript@3?bundle' 3</script>
Use
1import {h} from 'hastscript' 2import {isJavaScript} from 'hast-util-is-javascript' 3 4isJavaScript(h('script')) //=> true 5isJavaScript(h('script', {type: 'text/ecmascript'})) //=> true 6isJavaScript(h('script', {language: 'ecmascript'})) //=> true 7isJavaScript(h('script', {type: 'text/fooscript'})) //=> false 8isJavaScript(h('script', {language: 'fooscript'})) //=> false
API
This package exports the identifier
isJavaScript.
There is no default export.
isJavaScript(node)
Check if a node is a <script> that contains or references JavaScript.
Returns true if node is a <script> element that has a valid JavaScript
type, has no type and a valid JavaScript language, or has neither.
Parameters
node(Node) — node to check
Returns
Whether a node is a <script> that contains or references JavaScript
(boolean).
Syntax
HTML is parsed according to WHATWG HTML (the living standard), which is also followed by all browsers.
Syntax tree
The syntax tree used is hast.
Types
This package is fully typed with TypeScript.
Compatibility
Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of
Node.
This means we try to keep the current release line,
hast-util-is-javascript@^3,
compatible with Node.js 16.
Security
As rehype works on HTML and improper use of HTML can open you up to a
cross-site scripting (XSS) attack, use of rehype can also be unsafe.
Use rehype-sanitize to make the tree safe.
