AnchorJS

A JavaScript utility for adding deep anchor links (like these) to existing page content. AnchorJS is lightweight, accessible, and has no dependencies.

See Live Examples in the Documentation.

Installation

Download AnchorJS using npm,

npm install anchor-js

…and then include it into your project:

import AnchorJS from 'anchor-js';

const anchors = new AnchorJS();
anchors.add();

You could also include it in your webpage via a CDN like CDNJS or jsDelivr,

<script src="https://cdn.jsdelivr.net/npm/anchor-js/anchor.min.js"></script>
<script>
   anchors.add();
</script>

…or import it globally with ES Modules:

import 'https://cdn.jsdelivr.net/npm/anchor-js/anchor.min.js';

anchors.add();

Usage

See the Documentation for detailed instructions.

Compatibility

Currently Supports: IE9+ and modern browsers

Contributing

To contribute:

1. Fork/Clone the repo.
2. Make your changes (the main source file is anchor.js).
3. Write tests as needed.
4. Run tests locally to confirm everything is working:
   • Install test modules: Run npm ci
   • Run all tests: npm test
5. Minify and prepare the code: npm run build
6. Submit a Pull Request.

Docs

The docs site (in /docs) is a good place to test changes visually, because it has a lot of AnchorJS examples. The site can be viewed locally by opening /docs/index.html in a web browser. The docs are written in plain HTML and can be edited directly.

The version of AnchorJS used in the docs (docs-anchor.js) is a copy of the true source file (anchor.js), and is unminified (for easy testing, editing, and debugging). You don't need to include changes to docs-anchor.js in your PR. docs-anchor.js is overwritten to the latest version of AnchorJS source as part of npm run build (which is run when publishing a new version of anchor-js).
