Getting Started
Install: npm install --save @cliqz/adblocker-webextension
.
Usage
For a complete example check-out: @cliqz/adblocker-webextension-example.
Creating an instance of WebExtensionBlocker
and start blocking ads!
From the background page of your extension:
import { WebExtensionBlocker } from '@cliqz/adblocker-webextension';
WebExtensionBlocker.fromPrebuiltAdsAndTracking().then((blocker) => {
blocker.enableBlockingInBrowser(browser);
});
On Chromium-based browsers you will need a polyfill such as
webextension-polyfill
to get this working:
import { browser } from 'webextension-polyfill';
import { WebExtensionBlocker } from '@cliqz/adblocker-webextension';
WebExtensionBlocker.fromPrebuiltAdsAndTracking().then((blocker) => {
blocker.enableBlockingInBrowser(browser);
});
You are ready to block ads!
There are other ways you can create an instance of the blocking engine to
start blocking ads.
If you already have filters locally:
import { WebExtensionBlocker } from '@cliqz/adblocker-webextension';
const blocker = WebExtensionBlocker.parse(fs.readFileSync('easylist.txt', 'utf-8'));
Fetching lists from URLs:
import { WebExtensionBlocker } from '@cliqz/adblocker-webextension';
const blocker = await WebExtensionBlocker.fromLists(fetch, [
'https://easylist.to/easylist/easylist.txt'
]);
Use ready-made configs to block ads and optionally trackers:
import { WebExtensionBlocker } from '@cliqz/adblocker-webextension';
let blocker = await WebExtensionBlocker.fromPrebuiltAdsOnly();
blocker = await WebExtensionBlocker.fromPrebuiltAdsAndTracking();
Disabling Blocker in extension
To stop blocking ads:
blocker.disableBlockingInBrowser();
Caching Blocker using Serialization
To avoid having to create the same instance of WebExtensionBlocker
all over again,
you can serialize it to a byte-array which you can store on disk for faster
loading.
import { WebExtensionBlocker } from '@cliqz/adblocker-webextension';
WebExtensionBlocker.fromPrebuiltAdsAndTracking().then((blocker) => {
const buffer = blocker.serialize();
const restoredBlocker = WebExtensionBlocker.deserialize(buffer);
});
