Playwright is the new Puppeteer

Playwright is the new Puppeteer

TL;DR: Playwright is the successor of Puppeteer including support for all major browsers.

The most active contributors of Puppeteer Andrey Lushnikov and Joel Einbinder are now part of the team of Playwright. In one version of the repository’s README.md they stated:

We are the same team that originally built Puppeteer at Google but has since then moved on. With Playwright, we'd like to take it one step further and offer the same functionality for all the popular rendering engines. We'd like to see Playwright vendor-neutral and shared governed.

-- Playwright README.md: Q: How does Playwright relate to Puppeteer?

For now, I don’t have any reason to switch to Playwright

Playwright (vs. Puppeteer)

By default Playwright downloads Chromium, WebKit and Firefox browsers into the OS-specific cache folders, but you can also download single browser version.

Add-ons for Playwright

Playwright also has some Niek/playwright-addons albeit really basic ones (adblocker, stealth mode)

Code generation

Code generation aka “record command sequences”: Using script recorders

One can use included CLI microsoft/playwright-cli. CLI codegen command will attempt to generate resilient text-based selectors.

It works amazing in Windows

# codegen works on on Chrome
npx playwright-cli codegen example.com

Start any browser:

# Firefox?
npx playwright-cli ff example.com

# or in WebKit? Like Safari but on Windows
npx playwright-cli wk example.com

Using browser extension

Headless Recorder is a Chrome extension.

Using library

Besides codegen there is similar library QA Wolf

; required apt -y install libgbm-dev libnss3

I’ve had the same problem on Ubuntu 20.04. Fixed with installing these packages

sudo apt-get update sudo apt-get -y –no-install-recommends install libxrandr2 libatk1.0-0 libatk-bridge2.0-0 libx11-xcb1 libxcb-dri3-0 libxcomposite1 libxcursor1 libxdamage1 libcups2 libdrm2 libgbm1 libgtk-3-0

And it’s possible to see the list of missing libraries with ldd

ldd ./node_modules/puppeteer/.local-chromium/linux-*/chrome-linux/chrome | grep “not found”
