WelsonJS: Build Windows Apps Using Windows' Built-In JS Engine

WelsonJS combines Windows, Electron-like UI, and JavaScript into a lightweight framework tailored for systems with very limited computing resources. It runs on Windows (from XP SP3 to Windows 11 24H2) using the built-in JS engine (Chakra or MSHTML), requires no external dependencies, and supports script execution across console, GUI, and service environments. Key features include built-in transpilers (TypeScript, Rescript, CoffeeScript, LiveScript), Office automation tools, a Monaco-powered launcher UI, RPC clients, CLI network utilities, and support for JSON, YAML, and XML formats—all optimized for performance and security.
