Course Curriculum

Module 1: Electron Multi-Process Architecture & Process Lifecycle

  • Deconstructing Electron: Chromium rendering engine paired with Node.js runtime
  • The Main Process: Application lifecycle events, window creation, and hardware access
  • The Renderer Process: Rendering reactive web UIs with React 18, TypeScript, and Tailwind CSS
  • Managing multi-window architectures: Parent-child windows, modal dialogs, and offscreen views
  • Performance profiling: Tracking CPU spikes and memory consumption with Chromium DevTools

Module 2: Desktop Security Architecture & Context Isolation

  • Understanding Electron security risks: How nodeIntegration: true enables Remote Code Execution (RCE)
  • Hardening desktop apps: Enforcing contextIsolation: true and sandbox: true
  • The Preload Script paradigm: Exposing selective, immutable bridges via contextBridge
  • Content Security Policy (CSP): Crafting strict policies to prevent malicious XSS and script injection
  • Validating navigation: Intercepting will-navigate and new-window events to block untrusted external URLs

Module 3: Type-Safe Inter-Process Communication (IPC)

  • IPC fundamentals: Asynchronous vs synchronous communication patterns
  • Implementing modern invoke-handle patterns with ipcRenderer.invoke and ipcMain.handle
  • Architecting type-safe IPC contracts using shared TypeScript interfaces and DTOs
  • Defensive payload validation: Sanitizing every incoming renderer payload against prototype pollution
  • Handling high-throughput streaming data across IPC with backpressure management

Module 4: Native Systems Programming & Node-API C++ Addons

  • Extending Node.js with native code: Overview of Node-API (N-API) and C++ ABI stability
  • Compiling C++ addons with node-gyp and CMake.js to access low-level operating system APIs
  • Interfacing with Windows Win32 APIs, macOS Cocoa frameworks, and Linux system calls
  • Hardware communication: Controlling USB/Serial devices, thermal printers, and biometric scanners
  • Managing native memory buffers and thread-safe function callbacks with RAII patterns

Module 5: Native OS Integration & Offline-First Persistence

  • Desktop UX patterns: Frameless custom titlebars, window controls, and native dark/light themes
  • System Tray & Notifications: Background services, dock badges, tray menus, and native toast alerts
  • Global keyboard shortcuts: Registering system-wide hotkeys with globalShortcut APIs
  • Offline persistence: Local relational database architecture using SQLite3 and better-sqlite3
  • File system integration: Custom drag-and-drop file imports, file association handlers, and deep links

Module 6: Cross-Platform Packaging, Code Signing & Delta Auto-Updates

  • Distribution workflows: Packaging installers for Windows (NSIS .exe), macOS (.dmg), and Linux (.AppImage)
  • Cryptographic code signing: Bypassing Windows SmartScreen with EV certificates and Apple Notarization
  • Frictionless background auto-updates: Implementing delta updates via electron-updater and AWS S3
  • Crash telemetry & error reporting: Collecting native crash dumps using Breakpad/Crashpad and Sentry
  • Capstone Defense: Production-Hardened Cross-Platform Desktop Tool Deployed on GitHub
