cloudflare-puppeteer-extra

puppeteer-extra

A light-weight wrapper around @cloudflare/puppeteer and friends to enable cool plugins through a clean interface..

Installation

yarn add @cloudflare/puppeteer cloudflare-puppeteer-extra
# - or -
npm install @cloudflare/puppeteer cloudflare-puppeteer-extra

Quickstart

// cloudflare-puppeteer-extra is a drop-in replacement for @cloudflare/puppeteer,
// it augments the installed puppeteer with plugin functionality.
// Any number of plugins can be added through `puppeteer.use()`
const puppeteer = require("cloudflare-puppeteer-extra");

// Add stealth plugin and use defaults (all tricks to hide puppeteer usage)
const StealthPlugin = require("puppeteer-extra-plugin-stealth");
puppeteer.use(StealthPlugin());

// Add adblocker plugin to block all ads and trackers (saves bandwidth)
const AdblockerPlugin = require("puppeteer-extra-plugin-adblocker");
puppeteer.use(AdblockerPlugin({ blockTrackers: true }));

// That's it, the rest is puppeteer usage as normal 😊
puppeteer.launch({ headless: true }).then(async (browser) => {
  const page = await browser.newPage();
  await page.setViewport({ width: 800, height: 600 });

  console.log(`Testing adblocker plugin..`);
  await page.goto("https://www.vanityfair.com");
  await page.waitForTimeout(1000);
  await page.screenshot({ path: "adblocker.png", fullPage: true });

  console.log(`Testing the stealth plugin..`);
  await page.goto("https://bot.sannysoft.com");
  await page.waitForTimeout(5000);
  await page.screenshot({ path: "stealth.png", fullPage: true });

  console.log(`All done, check the screenshots. ✨`);
  await browser.close();
});

The above example uses the stealth and adblocker plugin, which need to be installed as well:

yarn add puppeteer-extra-plugin-stealth puppeteer-extra-plugin-adblocker
# - or -
npm install puppeteer-extra-plugin-stealth puppeteer-extra-plugin-adblocker

If you'd like to see debug output just run your script like so:

DEBUG=puppeteer-extra,puppeteer-extra-plugin:* node myscript.js

More examples

TypeScript usage

puppeteer-extra and most plugins are written in TS, so you get perfect type support out of the box. :)

import puppeteer from "puppeteer-extra";

import AdblockerPlugin from "puppeteer-extra-plugin-adblocker";
import StealthPlugin from "puppeteer-extra-plugin-stealth";

puppeteer.use(AdblockerPlugin()).use(StealthPlugin());

puppeteer
  .launch({ headless: false, defaultViewport: null })
  .then(async (browser) => {
    const page = await browser.newPage();
    await page.goto("https://bot.sannysoft.com");
    await page.waitForTimeout(5000);
    await page.screenshot({ path: "stealth.png", fullPage: true });
    await browser.close();
  });

Please check this wiki entry in case you have TypeScript related import issues.

Playwright usage

playright-extra with plugin support is available as well.

Multiple puppeteers with different plugins

const vanillaPuppeteer = require("puppeteer");

const { addExtra } = require("puppeteer-extra");
const AnonymizeUA = require("puppeteer-extra-plugin-anonymize-ua");

async function main() {
  const pptr1 = addExtra(vanillaPuppeteer);
  pptr1.use(
    AnonymizeUA({
      customFn: (ua) => "Hello1/" + ua.replace("Chrome", "Beer"),
    })
  );

  const pptr2 = addExtra(vanillaPuppeteer);
  pptr2.use(
    AnonymizeUA({
      customFn: (ua) => "Hello2/" + ua.replace("Chrome", "Beer"),
    })
  );

  await checkUserAgent(pptr1);
  await checkUserAgent(pptr2);
}

main();

async function checkUserAgent(pptr) {
  const browser = await pptr.launch({ headless: true });
  const page = await browser.newPage();
  await page.goto("https://httpbin.org/headers", {
    waitUntil: "domcontentloaded",
  });
  const content = await page.content();
  console.log(content);
  await browser.close();
}

Using with puppeteer-cluster

puppeteer-cluster allows you to create a cluster of puppeteer workers and plays well together with puppeteer-extra.

const { Cluster } = require("puppeteer-cluster");
const vanillaPuppeteer = require("puppeteer");

const { addExtra } = require("puppeteer-extra");
const Stealth = require("puppeteer-extra-plugin-stealth");
const Recaptcha = require("puppeteer-extra-plugin-recaptcha");

async function main() {
  // Create a custom puppeteer-extra instance using `addExtra`,
  // so we could create additional ones with different plugin config.
  const puppeteer = addExtra(vanillaPuppeteer);
  puppeteer.use(Stealth());
  puppeteer.use(Recaptcha());

  // Launch cluster with puppeteer-extra
  const cluster = await Cluster.launch({
    puppeteer,
    maxConcurrency: 2,
    concurrency: Cluster.CONCURRENCY_CONTEXT,
  });

  // Define task handler
  await cluster.task(async ({ page, data: url }) => {
    await page.goto(url);

    const { hostname } = new URL(url);
    const { captchas } = await page.findRecaptchas();
    console.log(`Found ${captchas.length} captcha on ${hostname}`);

    await page.screenshot({ path: `${hostname}.png`, fullPage: true });
  });

  // Queue any number of tasks
  cluster.queue("https://bot.sannysoft.com");
  cluster.queue("https://www.google.com/recaptcha/api2/demo");
  cluster.queue("http://www.wikipedia.org/");

  await cluster.idle();
  await cluster.close();
  console.log(`All done, check the screenshots. ✨`);
}

// Let's go
main().catch(console.warn);

For using with TypeScript, just change your imports to:

import { Cluster } from "puppeteer-cluster";
import vanillaPuppeteer from "puppeteer";

import { addExtra } from "puppeteer-extra";
import Stealth from "puppeteer-extra-plugin-stealth";
import Recaptcha from "puppeteer-extra-plugin-recaptcha";

Using with chrome-aws-lambda

If you plan to use chrome-aws-lambda with the stealth plugin, you'll need to modify the default args to remove the --disable-notifications flag to pass all the tests.

const chromium = require("chrome-aws-lambda");
const { addExtra } = require("puppeteer-extra");
const puppeteerExtra = addExtra(chromium.puppeteer);

const launch = async () => {
  puppeteerExtra
    .launch({
      args: chromium.args,
      defaultViewport: chromium.defaultViewport,
      executablePath: await chromium.executablePath,
      headless: chromium.headless,
    })
    .then(async (browser) => {
      const page = await browser.newPage();
      await page.goto(
        "https://www.spacejam.com/archive/spacejam/movie/jam.htm"
      );
      await page.waitForTimeout(10 * 1000);
      await browser.close();
    });
};

launch(); // Launch Browser

Using with Kikobeats/browserless

Kikobeats/browserless is a puppeteer-like Node.js library for interacting with Headless production scenarios.

const puppeteer = require("puppeteer-extra");
const StealthPlugin = require("puppeteer-extra-plugin-stealth");
puppeteer.use(StealthPlugin());

const browserless = require("browserless")({ puppeteer });

const saveBufferToFile = (buffer, fileName) => {
  const wstream = require("fs").createWriteStream(fileName);
  wstream.write(buffer);
  wstream.end();
};

browserless
  .screenshot("https://bot.sannysoft.com", { device: "iPhone 6" })
  .then((buffer) => {
    const fileName = "screenshot.png";
    saveBufferToFile(buffer, fileName);
    console.log(`your screenshot is here: `, fileName);
  });

Further info

Contributing

PRs and new plugins are welcome! 🎉 The plugin API for puppeteer-extra is clean and fun to use. Have a look the PuppeteerExtraPlugin base class documentation to get going and check out the existing plugins (minimal example is the anonymize-ua plugin) for reference.

We use a monorepo powered by Lerna (and yarn workspaces), ava for testing, TypeScript for the core, the standard style for linting and JSDoc heavily to auto-generate markdown documentation based on code. :-)

Kudos

• Thanks to skyiea for this PR that started the project idea.
• Thanks to transitive-bullshit for suggesting a modular plugin design, which was fun to implement.

Compatibility

puppeteer-extra and all plugins are tested continously in a matrix of current (stable & LTS) NodeJS and puppeteer versions. We never broke compatibility and still support puppeteer down to very early versions from 2018.

A few plugins won't work in headless mode (it's noted if that's the case) due to Chrome limitations (e.g. the user-preferences plugin), look into xvfb-run if you still require a headless experience in these circumstances.

Changelog

2.1.6 ➠ 3.1.1

2.1.6 ➠ 3.1.1

Big refactor, the core is now written in TypeScript 🎉 That means out of the box type safety for fellow TS users and nice auto-completion in VSCode for JS users. Also:

• A new addExtra export, to patch any puppeteer compatible library with plugin functionality (chrome-aws-lambda, etc). This also allows for multiple puppeteer instances with different plugins.

The API is backwards compatible, I bumped the major version just in case I missed something. Please report any issues you might find with the new release. :)

class: PuppeteerExtra

Modular plugin framework to teach puppeteer new tricks.

This module acts as a drop-in replacement for puppeteer.

Allows PuppeteerExtraPlugin's to register themselves and to extend puppeteer with additional functionality.

Example:

const puppeteer = require("puppeteer-extra");
puppeteer.use(require("puppeteer-extra-plugin-anonymize-ua")());
puppeteer.use(
  require("puppeteer-extra-plugin-font-size")({ defaultFontSize: 18 })
);
(async () => {
  const browser = await puppeteer.launch({ headless: false });
  const page = await browser.newPage();
  await page.goto("http://example.com", { waitUntil: "domcontentloaded" });
  await browser.close();
})();

---

.use(plugin)

• plugin PuppeteerExtraPlugin

Returns: this The same PuppeteerExtra instance (for optional chaining)

The main interface to register puppeteer-extra plugins.

Example:

puppeteer.use(plugin1).use(plugin2);

• See: PuppeteerExtraPlugin

---

.launch(options?)

• options Puppeteer.LaunchOptions? See puppeteer docs.

Returns: Promise<Puppeteer.Browser>

The method launches a browser instance with given arguments. The browser will be closed when the parent node.js process is closed.

Augments the original puppeteer.launch method with plugin lifecycle methods.

All registered plugins that have a beforeLaunch method will be called in sequence to potentially update the options Object before launching the browser.

Example:

const browser = await puppeteer.launch({
  headless: false,
  defaultViewport: null,
});

---

.connect(options?)

• options Puppeteer.ConnectOptions? See puppeteer docs.

Returns: Promise<Puppeteer.Browser>

Attach Puppeteer to an existing Chromium instance.

Augments the original puppeteer.connect method with plugin lifecycle methods.

All registered plugins that have a beforeConnect method will be called in sequence to potentially update the options Object before launching the browser.

---

.defaultArgs(options?)

• options Puppeteer.ChromeArgOptions? See puppeteer docs.

Returns: Array<string>

The default flags that Chromium will be launched with.

---

.executablePath()

Returns: string

Path where Puppeteer expects to find bundled Chromium.

---

.createBrowserFetcher(options?)

• options Puppeteer.FetcherOptions? See puppeteer docs.

Returns: Puppeteer.BrowserFetcher

This methods attaches Puppeteer to an existing Chromium instance.

---

.plugins

Type: Array<PuppeteerExtraPlugin>

Get a list of all registered plugins.

---

.getPluginData(name?)

• name string? Filter data by optional plugin name

Collects the exposed data property of all registered plugins. Will be reduced/flattened to a single array.

Can be accessed by plugins that listed the dataFromPlugins requirement.

Implemented mainly for plugins that need data from other plugins (e.g. user-preferences).

• See: PuppeteerExtraPlugin/data

---

defaultExport()

Type: PuppeteerExtra

The default export will behave exactly the same as the regular puppeteer (just with extra plugin functionality) and can be used as a drop-in replacement.

Behind the scenes it will try to require either puppeteer or puppeteer-core from the installed dependencies.

Example:

// javascript import
const puppeteer = require('puppeteer-extra')

// typescript/es6 module import
import puppeteer from 'puppeteer-extra'

// Add plugins
puppeteer.use(...)

---

addExtra(puppeteer)

• puppeteer VanillaPuppeteer Any puppeteer API-compatible puppeteer implementation or version.

Returns: PuppeteerExtra A fresh PuppeteerExtra instance using the provided puppeteer

An alternative way to use puppeteer-extra: Augments the provided puppeteer with extra plugin functionality.

This is useful in case you need multiple puppeteer instances with different plugins or to add plugins to a non-standard puppeteer package.

Example:

// js import
const puppeteerVanilla = require('puppeteer')
const { addExtra } = require('puppeteer-extra')

// ts/es6 import
import puppeteerVanilla from 'puppeteer'
import { addExtra } from 'puppeteer-extra'

// Patch provided puppeteer and add plugins
const puppeteer = addExtra(puppeteerVanilla)
puppeteer.use(...)
