Setup

Alder uses ES6 Imports/Exports, so it can be imported using import Alder from '{link}.js'.

Alder is also available from NPM (package).

To use in an NPM project:

npm i alder.js

"dependencies": {
    "alder.js": "~0.2.1"
    // ...
}

To use within your JavaScript/TypeScript file:

const { Alder } = require("alder.js");
let alder = new Alder();
// ...

Constructor

The constructor accepts a Boolean value that determines whether Alder is run automatically. It defaults to true. If an argument is not provided, all elements that match * > style are parsed.

let alder = new Alder(); // will parse all style elements within '* > style' elements

parse(element)

Accepts a single live node. The node should be the parent of the style attribute you wish to scope. If no arguments are provided, the parse method returns false.

let alder = new Alder(false);
alder.parse(document.body.querySelector('style').parentElement) // will parse the style elements within the parent of the first style element

Notes

When scoping pseudo-elements and pseudo-classes, if the parent element doesn't have a unique id, a data-alder attribute is added so that scoping can take place.

Not Parsed
