Desktop and Mobile Apps with Rust and Tauri 2
Class Duration
21 hours of live training delivered over 3-5 days to accommodate your scheduling needs.
Student Prerequisites
- Working Rust experience equivalent to Rust Essentials
- Comfort with HTML, CSS, and a JavaScript or Rust-based UI framework
- Familiarity with the command line and Git
Target Audience
Engineers building cross-platform desktop applications — internal tools, developer tools, AI/LLM workstation apps, on-device productivity software — who want native performance, small binaries, and a tight security model. Also relevant for teams shipping the same app to desktop and mobile, since Tauri 2 supports iOS and Android.
Description
Tauri 2 became stable in October 2024 and is now the production-ready alternative to Electron for cross-platform desktop apps — and a viable mobile target as well. This course teaches engineers to build, ship, and operate small, fast, secure Tauri 2 apps on the Rust 2024 edition (1.85 introduced the edition; 1.95+ recommended for the current toolchain). It covers project setup with the customer's preferred frontend (Leptos, React, Vue, Svelte, or Solid), the Rust backend, the Tauri 2 capability/permission model (ACL), native context menus, file-system and OS interactions, mobile-specific APIs (notifications, dialogs, NFC, biometrics, deep links), and the full distribution story (signed installers, auto-update, App Store and Play Store packaging). Throughout, students use AI coding assistants (Claude Code, Cursor, GitHub Copilot) the way senior Rust engineers actually use them in 2026 — letting Cargo, clippy, and the compiler be the source of truth on the Rust side and AI handle the routine boilerplate.
Learning Outcomes
- Stand up a Tauri 2 project with the customer's preferred frontend and a Rust backend.
- Define and call backend Rust commands from the frontend with proper argument and error handling.
- Use the Tauri 2 capability/ACL model to ship apps that follow least-privilege.
- Build native UI affordances: windows, menus, tray icons, native context menus, dialogs, notifications, splash screens.
- Connect to the file system, the database, and remote APIs from the Rust side.
- Target iOS and Android with the same Tauri 2 codebase, including platform-specific APIs.
- Build, sign, and distribute installers across macOS, Windows, Linux, and the mobile stores.
- Use AI coding assistants effectively for Tauri 2 development without sacrificing the security model.
Training Materials
All students receive comprehensive courseware covering all topics in the course. Courseware is distributed via GitHub in the form of documentation and extensive code samples. Students practice the topics covered through challenging hands-on lab exercises that build into a complete signed Tauri 2 desktop app capstone, with optional mobile builds.
Software Requirements
A free GitHub account, the latest stable Rust toolchain installed via rustup (Rust 1.95+ on the 2024 edition), Visual Studio Code or another supported editor with the rust-analyzer extension, Node.js 22+ (if a JavaScript frontend is chosen), Docker for the local PostgreSQL instance (if the database lab is included), platform tooling for the chosen target OS (Xcode, Android SDK, etc.), and an AI coding assistant of choice (GitHub Copilot, Cursor, or Claude Code). A cloud-based environment can be provided if local installation is restricted.
Training Topics
Tauri 2 in 2026
- What changed in Tauri 2: stable since October 2024, mobile support, ACL-based capabilities, native context menus
- Tauri 2 vs. Electron, Qt, .NET MAUI, and Flutter
- The architecture: Rust backend, native webview frontend
- Why Tauri produces dramatically smaller and faster binaries than Electron
- The roadmap and ecosystem in 2026
Getting Started
- Creating a Tauri 2 project
- Choosing the frontend: Leptos, React, Vue, Svelte, or Solid
- Project structure,
tauri.conf.json, and capability files - Running and debugging Tauri 2 apps
Frontend ↔ Backend Communication
- Defining Rust commands with
#[tauri::command] - Calling commands from the frontend with
invoke - Argument and return-type conversions
- Error handling across the boundary
- Async commands and long-running tasks
App Architecture and State
- The
App,AppHandle, andWindowAPIs - Managed state with
tauri::State - Event-driven communication:
emitandlisten - Multi-window apps and inter-window messaging
Native UI Elements
- Windows, sizing, and platform-specific behavior
- Application menus and per-window menus
- Native context menus (powered by muda)
- Tray icons with menus and actions
- Splash screens
- Native dialogs and notifications
Capabilities and the Permission Model (ACL)
- Why ACL replaces the v1 allowlist
- Defining capabilities for windows and contexts
- Plugin permissions and scoping
- Threat model: what a compromised webview can and cannot do
- Auditing AI-generated capability files before shipping
Operating-System Integration
- File system: pickers, watchers, paths, and permissions
- Clipboard, deep links, and protocol handlers
- Shell and process integration
- Auto-launch and background services
- The Tauri plugin ecosystem (notification, dialog, fs, store, sql, http, updater, …)
Mobile (iOS and Android)
- Setting up mobile targets
- Mobile-specific plugins: notifications, dialogs, NFC, barcode reading, biometric auth, clipboard, deep links
- Platform-specific Rust code with
#[cfg(...)] - Building, signing, and submitting to the App Store and Play Store
Database and Network
- Connecting to PostgreSQL with sqlx (or SQLite for embedded use)
- Calling REST APIs with
reqwest - Caching and offline-first patterns
- Background sync and push
Building and Distributing
- Platform-specific installers:
.dmg,.msi,.AppImage,.deb,.rpm - Code signing on macOS and Windows
- Auto-update with the updater plugin
- Cross-platform CI/CD with GitHub Actions
- Mobile distribution via the App Store and Play Store
AI-Assisted Tauri 2 Development
- Where AI assistants help on Tauri 2 boilerplate (commands, plugins, frontend bindings) and where they don't (capability files, security boundaries)
- Prompts that work well for Tauri 2 plugin authoring and command design
- Letting the compiler, clippy, and tests catch what AI gets wrong
- Reviewing AI-generated capability files before shipping
- Agentic Rust workflows for Tauri 2: AI-assisted refactors, code review, and CI
Capstone
- Build and ship a small Tauri 2 desktop app: a Rust backend with a chosen frontend, a sensible capability file, native menus, file-system integration, a database, signed installers for at least two platforms, and optionally a mobile build — built with AI assistance and validated by the compiler, clippy, and tests
- Course wrap-up and recommended next courses
