A fast, pure-JavaScript content-blocking library made by Cliqz.

This library is the building block technology used to power Cliqz and Ghostery's Adblocking. Being a pure JavaScript library, it can be used for various purposes such as:

• Building a content-blocking extension (see this example for a minimal content-blocking webextension)
• Building tooling around popular block-lists such as EasyList
• Converting between various formats of filters (EasyList, Safari Block Lists, etc.)
• Detecting duplicates in lists
• Detecting dead domains
• etc.

The library provides the low-level implementation to fetch, parse and match filters; which makes it possible to manipulate the lists at a high level.

Install dependencies:

$ npm install

Build:

$ npm run bundle

Test:

$ npm run test

You can use the following bundle: adblocker.umd.js.

To publish a new version:

1. Update version in package.json
2. Update CHANGELOG.md
3. New commit on local master branch (e.g.: Release v0.1.x)
4. Add new tag git tag -f -a vX.Y.Z -m "vX.Y.Z"
5. Push release commit + tag git push upstream master --tags
6. Travis takes care of the rest!
