Answer 1

You can pass in a proxy like this in an argument,

const options = {
        headless: false,
        args: [
            `--proxy-server=${proxyIP:proxyPORT}`,
            `--ignore-certificate-errors`
        ]
};
const browser = await puppeteer.launch(options);

If you want proxy authentication, you can use the following in your page object,

await page.authenticate(user, pass);

Answer 2

I made a module that does this. It's called puppeteer-page-proxy . It supports setting a proxy for an entire page, or if you like, it can set a different proxy for each request.

First install it:

npm i puppeteer-page-proxy

Then require it:

const useProxy = require('puppeteer-page-proxy');

Using it is easy; Set proxy for an entire page:

await useProxy(page, 'http://127.0.0.1:8000');

If you want a different proxy for each request,then you can simply do this:

await page.setRequestInterception(true);
page.on('request', req => {
    useProxy(req, 'socks5://127.0.0.1:9000');
});

Then if you want to be sure that your page's IP has changed, you can look it up;

const data = await useProxy.lookup(page);
console.log(data.ip);

It supports http , https , socks4 and socks5 proxies, and it also supports authentication if that is needed:

const proxy = 'http://login:pass@127.0.0.1:8000'
