介绍

Puppeteer is a Node.js library that provides a high-level API to control headless browsers such as Google Chrome or Chromium.
It allows users to automate interactions with web pages, such as clicking buttons, filling out forms, and scraping data.

Features

Headless Browser Automation: Puppeteer allows you to launch a browser in headless mode, meaning that it runs without a graphical user interface. This makes it ideal for automated testing and web scraping.
DOM Manipulation: Puppeteer provides methods to interact with the DOM of a web page, allowing you to simulate user interactions like clicks and keyboard input.
Network Interception: You can intercept and modify network requests made by the browser using Puppeteer, making it easy to mock responses or block certain requests.
Screenshot and PDF Generation: Puppeteer can capture screenshots of web pages or generate PDFs from them, useful for generating reports or visual regression testing.
Performance Monitoring: Puppeteer can be used to measure the performance of web pages by recording metrics such as page load time, network requests, and JavaScript execution time.

Automated Testing: Puppeteer is commonly used for writing end-to-end tests for web applications. It allows developers to simulate user interactions and verify expected behavior.
Web Scraping: Puppeteer can be used to extract data from websites by navigating through pages and extracting information from the DOM.
SEO Testing: Developers can use Puppeteer to render web pages and check how they are indexed by search engines, ensuring that important content is visible to crawlers.
Monitoring Web Performance: Puppeteer can be used for monitoring the performance of web pages over time, identifying areas for optimization.
