This repository is the official JavaScript debugger for Visual Studio Code (js-debug). It implements a full Debug Adapter Protocol (DAP) server that communicates with JavaScript runtimes via the Chrome DevTools Protocol (CDP). The debugger supports Node.js, Chrome, Edge, WebView2, VS Code extension hosts, Blazor, and WebAssembly (with DWARF symbols). The architecture is modular, with a core adapter layer handling breakpoints, source maps, evaluation, and console output; target-specific launchers for Node and browser processes; a UI layer providing VS Code commands, configuration providers, and profiling tools; and extensive telemetry and diagnostics infrastructure. Key entry points include the VS Code extension activation (`src/extension.ts`) and a standalone DAP server (`src/debugServerMain.ts`). The codebase uses dependency injection (Inversify), custom event emitters, and source map management with caching and rename support. External dependencies include `ws` (WebSocket), `got` (HTTP), `acorn`/`astring` (JavaScript parsing/code generation), and `@jridgewell/trace-mapping` (source map resolution). While primarily an application, it includes a diagnostic tool webview and telemetry for operational analysis.
Wild Web Developer is an Eclipse IDE plugin that integrates a suite of language servers (HTML, CSS, JavaScript/TypeScript, JSON, YAML, XML, Markdown, Vue, Angular, Astro, ESLint) and debug adapters (Node.js, Chrome, Firefox, npm) into the Eclipse workbench. It uses Language Server Protocol (LSP) via LSP4E and TextMate grammars for syntax highlighting, and Debug Adapter Protocol (DAP) via LSP4E's debug support. The plugin bundles an embedded Node.js runtime to execute external language servers and debug adapters, and provides extensive preference pages for each supported language. The architecture is a standard Eclipse RCP plugin with extension points for schema association and LemMinX extensions. The codebase demonstrates solid engineering practices with a clear separation between language server clients, debug delegates, and UI components, though some parts (e.g., preference pages) suffer from copy-paste duplication. It is actively maintained with frequent dependency updates and a comprehensive test suite.
This repository is a Visual Studio Code extension for developing, debugging, and simulating Apache Cordova and Ionic mobile applications. It provides a comprehensive debug adapter that supports launching and attaching to Android, iOS, browser, and simulated targets. The extension integrates with the Chrome DevTools Protocol (CDP) via a custom proxy to enable sourcemap rewriting and cross-platform debugging, and it offers IntelliSense for Cordova plugin APIs and Ionic framework components. It also includes commands for building, running, preparing, and cleaning Cordova/Ionic projects, as well as telemetry and localization support across 14 languages. The architecture is modular: the core debug session (`CordovaDebugSession`) delegates to platform-specific implementations (`AndroidPlatform`, `IosPlatform`, `BrowserPlatform`) that inherit from abstract base classes (`AbstractPlatform`, `AbstractMobilePlatform`). A CDP proxy layer (`CordovaCDPProxy`) intercepts and transforms messages between the debugger and the target runtime, with specialized message handlers for Chrome and Safari runtimes. Target management is handled by `MobileTargetManager` subclasses (`AndroidTargetManager`, `IOSTargetManager`) that enumerate devices and emulators. The extension also includes a plugin simulator (`PluginSimulator`) that serves the app via `cordova-simulate` and a Socket.IO connection. Key entry points include the extension activation (`src/extension/cordova-extension.ts`), the debug configuration provider (`src/extension/debugConfigurationProvider.ts`), and the debug session class (`src/debugger/cordovaDebugSession.ts`). External dependencies include the Cordova CLI, Ionic CLI, Android SDK, iOS toolchain (Xcode, ios-webkit-debug-proxy), and npm packages like `cordova-simulate`, `socket.io-client`, and `vscode-js-debug-browsers`. The codebase is written in TypeScript and uses Gulp and Webpack for building. While the extension is functionally complete and well-structured, it shows signs of technical drift: many dependencies are outdated (e.g., `applicationinsights` 0.15.6, `socket.io-client` 2.4.0), the Cordova ecosystem has declined in favor of Capacitor, and the large i18n file set (200+ files) adds maintenance overhead. The code contains some legacy patterns (e.g., `eval` for custom require, extensive use of `any` types) and hardcoded timeouts. Despite this, the core abstractions for platform handling and CDP message processing are well-designed and potentially reusable.
