Puppeteer

info

Currently, Browserless V2 is available in production via two domains: production-sfo.browserless.io and production-lon.browserless.io

Puppeteer is well-supported by browserless, and is easy to upgrade an existing service or app to use it.

Basic Usage

In order to use the browserless service, simply change the following:

Before browserless

import puppeteer from "puppeteer";

const browser = await puppeteer.launch();
const page = await browser.newPage();
// ...

After browserless

import puppeteer from "puppeteer";

const browser = await puppeteer.connect({
  browserWSEndpoint: `wss://production-sfo.browserless.io?token=YOUR_API_TOKEN_HERE`,
});
const page = await browser.newPage();

info

If you're running the docker container to replace the location of wss://production-sfo.browserless.io/ to wherever your container is running.

Specifying launch flags

You can specify launch-arguments through an object sent on a query string inside the browserWSEndpoint. As an example, if you want to start the browser with a pre-defined width and height, in headful mode and setting stealth, you can specify it like so:

import puppeteer from "puppeteer-core";

const launchArgs = JSON.stringify({
  args: [`--window-size=1920,1080`, `--user-data-dir=/tmp/chrome/data-dir`],
  headless: false,
  stealth: true,
  timeout: 5000,
});

const browser = await puppeteer.connect({
  browserWSEndpoint: `wss://production-sfo.browserless.io/?token=YOUR_API_TOKEN_HERE&launch=${launchArgs}`,
});

//...

Connecting to unlocked browser sessions

If your Puppeteer scripts are getting blocked by bot detectors, you can use BrowserQL to generate a browser instance with advanced stealth features, that you can then connect to with the provided browserWSEndpoint and cookies.
