Installation

Using npm:

npm i @horat1us/detect-ad-block@^1.0

Usage

import { DetectAdBlock } from "@horat1us/detect-ad-block";

function detect() {
    const detectAdBlock = DetectAdBlock();
    detectAdBlock.perform({ timeout: 1000 })
        .then((result) => {
            console.log(result ? `AdBlock Detected` : `AdBlock Not Found`);
        })
        .catch((error) => {
            console.error(`Error while AdBlock checking: `, error);
        });
}
const timeout = 5000;

// You may use window.onload, document.onreadystatechange etc.
if (window.requestIdleCallback) {
    window.requestIdleCallback(detect, timeout);
} else {
    setTimeout(detect, timeout)
}

Note: You should not run adblock checking directly on or after page load.

DetectPlugin

You may use built-in plugins:

• http:ajax (default) - http request block detection using XMLHttpRequest (AJAX)
• html (default) - html element block detection
• http:script - http request block detection using script tag (<script src="/ad/.... />)

Also, you may implement custom plugin using DetectPlugin interface.

import { DetectAdBlock, plugins } from "@horat1us/detect-ad-block";

const detectAdBlock = DetectAdBlock([
    // your plugins list
    plugins.ajax,
    plugins.script,
    plugins.html,
    // using built-in plugin with custom options
    plugins.Html({
        name: "custom-html",
        baitStyle: "...",
        baitClass: "...",
        interval: 100,
        timeout: 950,
    }),
    // or custom plugin
    {
        name: "custom-plugin",
        version: 1,
        detect(resolve) {
            const result = performSomeCheck();
            resolve(result);
        },
    },
])
