class-references

> A framework-agnostic library for managing multiple references to class names.

For more details, see the main README file.

Installation

Using npm:

``
npm install --save class-references
`

Using yarn:

`
yarn add class-references
`

Usage

Any time you want to add a class (eg. MyClassName) to an element (eg. document.body), use:

`js
import { requestTokenForClass } from "class-references";

const token = requestTokenForClass(document.body, "MyClassName");
`

When you're ready to remove the class, make sure you can recall the token, and use:

`js
import { releaseToken } from "class-references";

releaseToken(document.body, token);
`

$3

`js
import { releaseToken, requestTokenForClass } from "class-references";

const className = "u-preventScroll";
const element = document.body;

const token1 = requestTokenForClass(element, className); // Class is added
const token2 = requestTokenForClass(element, className); // Class was already added, but another token reserves it.

releaseToken(element, token1); // token1 is released; token2 not released, class remains
releaseToken(element, token2); // both tokens are released, class removed
