Overview
This skill is a practical guide for building cross-platform desktop applications using web technologies. It focuses on Electron and Tauri, showing when to choose each, core architecture patterns, and concrete code and build examples. Use it to accelerate delivery of performant, secure desktop apps for Windows, macOS, and Linux from a single codebase.
How this skill works
The guide inspects key tradeoffs and provides step-by-step patterns for project creation, process separation, IPC bridges, and native integrations. It includes starter commands, recommended folder layouts, main/preload/renderer examples for Electron, and Rust command patterns plus frontend invoke examples for Tauri. It also covers packaging, auto-update, and platform-specific deployment tasks.
When to use it
- When you want a single codebase (HTML/CSS/JS) that runs on Windows, macOS, and Linux
- When you need deep system access (filesystem, tray, global shortcuts) not available on the web
- When you want a lightweight, secure runtime (prefer Tauri) or mature Node integration (Electron)
- When offline-first behavior and native packaging are required
- When planning auto-update and code-signing workflows for desktop distribution
Best practices
- Prefer Tauri for smaller bundles, lower memory, and Rust-backed safety; choose Electron for heavy Node.js needs and ecosystem maturity
- Separate processes: keep system APIs in the main/backend and expose a minimal, typed bridge to the renderer
- Use secure IPC patterns (contextBridge in Electron, invoke handlers in Tauri) and never expose raw Node APIs to the UI
- Plan platform-specific UI/UX (menus, shortcuts, window controls) and test on each target OS early
- Include code signing, auto-update, and notarization in your CI/CD plan before release
Example use cases
- A lightweight note-taking app using Tauri that syncs to the cloud and works offline
- A VS Code–style editor built on Electron that needs extensive Node.js integrations and plugins
- A productivity tool with system tray, global shortcuts, and file-system batch operations
- An internal enterprise app that requires native installers, auto-update, and strict security controls
FAQ
Choose Tauri for smaller bundles, lower memory footprint, and Rust security; pick Electron when you need mature Node.js integrations or existing Electron tooling.
How do I securely expose native features to the UI?
Expose a minimal, well-typed API via contextBridge (Electron) or tauri invoke handlers, validate inputs, and keep privileged code out of the renderer.
