Puppeteer is a JavaScript library providing a high-level API to control Chrome or Firefox browsers headless by default, designed for developers automating web tasks like testing and scraping.

---

🚀 Overview

Puppeteer is a powerful Node.js library developed by the Chrome DevTools team that lets you control Chrome or Firefox programmatically through the DevTools Protocol or WebDriver BiDi. It excels at automating browser interactions, making it perfect for end-to-end testing, web scraping, generating screenshots and PDFs, and more.

What problem does this project solve? It abstracts the complexity of low-level browser protocols, allowing developers to easily launch browsers, navigate pages, interact with elements, and handle dynamic content without manual intervention.

Who is it built for? Primarily developers, QA engineers, and anyone needing browser automation in JavaScript/Node.js environments.

Why did you build it? To provide a simple, high-level API for reliable browser automation, born from needs within the Chrome team and open-sourced for the community.

✨ Key Features

• Launch and control headless Chrome or Firefox browsers programmatically.
• Navigate to URLs, set viewports, simulate keyboard/mouse interactions, and wait for elements or network events (what it does and why it matters: enables realistic user simulation for testing).
• Powerful locator API using ARIA roles and text for robust element selection.
• Capture screenshots, generate PDFs, and extract content from pages.
• Optional: puppeteer-core for lightweight installs without bundled browser; experimental Firefox support via WebDriver BiDi.
