SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Developers building Tauri desktop applications often struggle to choose and correctly implement secure communication between the web frontend and the Rust backend, risking exposed commands or misconfigured security patterns. ## Core Features & Use Cases - IPC Primitives Reference: Covers Events (bidirectional fire-and-forget messaging) and Commands (JSON-RPC-style invocation) with Rust and TypeScript code examples. - Brownfield vs Isolation Guidance: Explains when to use the default brownfield pattern versus the isolation pattern with AES-GCM encryption and sandboxed iframe validation. - Security Best Practices: Provides input validation patterns, command whitelisting, and typed argument handling for hardened IPC surfaces. - Use Case: When building a Tauri app that reads files from disk, use this Skill to implement an isolation hook that blocks path traversal attempts and validates every invoke call before it reaches Rust. ## Quick Start Ask the assistant to explain the difference between Tauri's brownfield and isolation IPC patterns and show how to configure an isolation hook for your app.

FAQPage Schema
How do I call a Rust function from the frontend in Tauri?

Define a Rust function with the #[tauri::command] attribute, register it via tauri::generate_handler!, then call it from the frontend using invoke() from @tauri-apps/api/core. Arguments and return values must be JSON-serializable.

What is the difference between Tauri brownfield and isolation patterns?

Brownfield is the default pattern with no extra configuration, giving the frontend direct access to commands. Isolation intercepts all IPC messages in a sandboxed iframe, validates them, and encrypts them with AES-GCM before they reach Tauri Core.

When should I use the Tauri isolation pattern?

Use isolation for public-facing applications, apps handling sensitive data, or projects with many third-party frontend dependencies where supply chain attacks are a concern. Tauri recommends isolation whenever feasible for production applications.

How do Tauri events differ from commands?

Events are bidirectional fire-and-forget messages used for lifecycle notifications and state changes, emitted with app.emit() in Rust or emit() in the frontend. Commands are frontend-to-backend request-response calls built on a JSON-RPC-style abstraction.

What are the limitations of the Tauri isolation pattern?

ES Modules do not load in sandboxed iframes on Windows, so isolation scripts must be inlined at build time without bundlers. The isolation app should avoid external dependencies and keep validation logic minimal.

How do I validate IPC calls in a Tauri isolation hook?

Define window.__TAURI_ISOLATION_HOOK__ in your isolation script to inspect each payload before it reaches Tauri Core. Return null to block unauthorized commands or paths, and use a whitelist of allowed command names for strict validation.
