Debugger
本项目是一个浏览器开发者工具，旨在检查 JavaScript 执行、网络流量和页面布局。它作为一个 JavaScript 调试器和 Chrome DevTools 协议调试器，用于管理 Web 引擎的状态并识别 Web 应用中的逻辑错误。
该套件提供专门的 Web 性能分析工具，包括内存泄漏检测和处理瓶颈分析。它还包含一个网络流量分析器，用于排查 API 调用，以及一个浏览器存储管理器，用于修改 Cookie、缓存和本地数据库条目。
其他功能涵盖 Web 页面布局分析、用于验证响应式显示的移动设备模拟，以及应用日志监控。该工具集支持源映射（Source Map）解析，将编译后的代码链接回原始文件，并允许连接外部编辑器。
Features
- Browser Developer Tools - Provides a comprehensive suite of debugging utilities for inspecting JavaScript execution, network traffic, and page layouts within a browser.
- JavaScript and TypeScript Debugging - Provides comprehensive tools for stepping through, inspecting, and profiling JavaScript execution to resolve logic errors.
- Browser Storage Managers - Provides an interface for modifying and deleting cookies, cache, and local database entries like IndexedDB.
- Client-Side Storage - Provides mechanisms for persisting and modifying application data within the browser environment.
- JavaScript Runtime Debuggers - Provides a runtime debugger for stepping through code and inspecting variables to identify logic errors in JavaScript.
- JSON-Based Communication Protocols - Uses a standardized JSON-based protocol to exchange commands and state between the browser engine and the developer interface.
- Network Traffic Analyzers - Monitors outgoing requests and responses to troubleshoot API calls and optimize loading speeds.
- Remote Debugging Protocols - Provides a protocol for connecting the frontend toolset to a background process that controls the JavaScript engine.
- Inter-Process Message Passing - Coordinates structured data exchange between the main browser process and the separate renderer process hosting the tools.
- Web Performance Analyzers - Provides tools for analyzing memory usage and identifying processing bottlenecks to improve page responsiveness.
- Network Traffic Monitors - Includes a network traffic monitor to track API calls and asset requests for troubleshooting and optimization.
- Page Speed Optimizations - Analyzes memory usage and processing bottlenecks to improve the speed and responsiveness of web pages.
- DevTools Protocol Clients - Implements a client that uses the Chrome DevTools Protocol to inspect JavaScript execution and manage the web engine state.
- Layout Analysis Tools - Allows real-time inspection of HTML and CSS properties to refine the visual structure of a website.
- Source Map Resolution - Maps minified or compiled JavaScript back to original source files for accurate line-by-line debugging.
- Browser Device Emulation - Simulates different device categories and user agents to verify that layouts adapt correctly to mobile displays.
- Application Performance Optimization - Identifies processing bottlenecks and streamlines asset delivery to increase the speed of the user experience.
- Real-Time Application Log Monitoring - Tracks errors, security warnings, and network issues through a real-time console output for troubleshooting.
- Memory Leak Detection - Analyzes memory usage patterns to identify leaks and improve overall application responsiveness.
- DOM and Style Inspectors - Analyzes structural properties and styling in real time to adjust and refine the visual arrangement of a page.
- Mobile Viewport Emulation - Provides a mechanism to simulate various mobile device viewports to verify responsive web layouts.
