Activity of puppeteer/puppeteer repository

Puppeteer is a headless Chrome or Chromium browser node API that can be utilized to achieve browser automation. Essentially, it allows developers to write scripts that can perform actions on a web page, such as clicking buttons, filling out forms, and capturing screenshots, among other things, much like a human would do.

Here are some key features of Puppeteer:

1. It provides a high-level API to control headless (or non-headless) Chrome over the DevTools Protocol.
2. It runs headless by default, but can be configured to run full (non-headless) Chrome.
3. The API is designed to be familiar for JavaScript developers.
4. It supports network interception, which could be useful to emulate different network conditions.

Various tasks you can perform with Puppeteer:

• Generate screenshots and PDFs of pages.
• Scrape website data which doesn't provide an API or if the API isn't sufficient.
• Automate form submission, UI testing, keyboard input, etc.
• Create up-to-date, automated testing environment with latest Chrome versions.
• Capture a timeline trace of your site, to help diagnose performance issues.

However, it's important to note that using Puppeteer in server-side rendering situations can be heavy as it downloads a full version of Chromium (~170Mb Mac, ~282Mb Linux, ~280Mb Win).

The repository includes useful resources such as example codes and API documentation for users to kick-start their projects. Pull requests for new features or bug fixes are also welcomed.
