How To Use Puppeteer Proxy With Authentication

The proxy-chain NPM package is an open source tool created and maintained by Apify that takes a different route by allowing you to simply “anonymize” an authorized proxy.

This is accomplished by sending your proxy address along with authentication information to the proxyChain.anonymizeProxy function and then getting its value as the —proxy-server parameter when running Puppeteer.

const puppeteer = require('puppeteer');
const proxyChain = require('proxy-chain');

const proxy = 'http://your.proxy.address:9000';
const username = 'your_proxy_username';
const password = 'your_proxy_password';

(async () => {
    const originalUrl = `http://${username}:${password}@${proxy}`;

    // Return anonymized version of original URL - looks like http://127.0.0.1:16383
    const newUrl = await proxyChain.anonymizeProxy(originalUrl);

    const browser = await puppeteer.launch({
        args: [`--proxy-server=${newProxyUrl}`],
    });

    const page = await browser.newPage();

    await page.goto('https://www.google.com');

    await browser.close();

    // Close any pending connections
    await proxyChain.closeAnonymizedProxy(newProxyUrl, true);
})();

When utilizing this approach, it is vital to remember that after exiting the browser, you should use the closeAnonymizedProxy() function to forcefully close any pending connections.

This software handles both simple HTTP proxy forwarding and HTTP CONNECT tunneling to enable protocols like HTTPS and FTP. It also offers many more functionalities, thus it is interesting to explore for other applications.
