Let's start by creating a new directory and navigating to it. Assuming you already have Node.js (opens new window) available in your local environment, installing Puppeteer or Playwright is achieved with just one instruction:
Puppeteer and Playwright come bundled with their respective browsers, so we now have all we need to run our first script. Let's create a script to navigate to our test website (opens new window):
Run this example as follows:
Nothing much has happened, right? Remember: by default, Puppeteer and Playwright will run in headless mode! That means we won't see anything of what is happening in the browser when our script runs.
Puppeteer/Playwright creates its own browser user profile, which it cleans up on every run. In other words: all runs will be sandboxed and not interfere with one another, as state is always fully reset at the end of a session.
When you are first writing and debugging your scripts, it is a good idea to disable headless mode so you can have a look at what your script is doing:
After executing the updated file, you will see Chromium starting up, only to shut down after an instant. Everything is working as expected! Our script is just so short, it runs almost instantaneously.
