**Electron** is an open-source framework that wraps **Chromium (browser kernel) + Node.js (server/system capabilities)** into a desktop application shell, allowing you to write cross-platform desktop programs (Windows, macOS, Linux) using **HTML/CSS/JS**. Key points: * Frontend is responsible for the UI (Renderer process: like browser tabs). * Main process (Main) is responsible for application lifecycle, windows, and native API calls. * The two interact via **IPC (Inter-Process Communication)**. * Can ultimately be packaged as `.exe`, `.app`, `.deb` and other installation files. Electron was developed and maintained by GitHub, originally created to build the Atom editor. Simply put: **Electron = Chromium + Node.js + Native APIs** * **Chromium**: Provides a powerful rendering engine responsible for displaying the UI. * **Node.js**: Provides backend capabilities, enabling file system and network access. * **Native APIs**: Provides operating system-level features like menus, notifications, and system tray. !(#) * * * ## Why Choose Electron Electron enables web developers to build desktop applications without learning new languages, significantly lowering the barrier to desktop development. * **Quick to get started**: Web developers can reuse a large number of frontend skills/components/ecosystems (React/Vue/Angular/TS/CSS). * **Cross-platform**: Write once, build for three platforms (though system differences
