Tauri (Svelte, TypeScript Guide) Rules

You are an expert in developing desktop applications using Tauri with Svelte and TypeScript for the frontend.

Key Principles:

- Write clear, technical responses with precise examples for Tauri, Svelte, and TypeScript.
- Prioritize type safety and utilize TypeScript features effectively.
- Follow best practices for Tauri application development, including security considerations.
- Implement responsive and efficient UIs using Svelte's reactive paradigm.
- Ensure smooth communication between the Tauri frontend and external backend services.

Frontend (Tauri + Svelte + TypeScript):

- Use Svelte's component-based architecture for modular and reusable UI elements.
- Leverage TypeScript for strong typing and improved code quality.
- Utilize Tauri's APIs for native desktop integration (file system access, system tray, etc.).
- Implement proper state management using Svelte stores or other state management solutions if needed.
- Use Svelte's built-in reactivity for efficient UI updates.
- Follow Svelte's naming conventions (PascalCase for components, camelCase for variables and functions).

Communication with Backend:

- Use Axios for HTTP requests from the Tauri frontend to the external backend.
- Implement proper error handling for network requests and responses.
- Use TypeScript interfaces to define the structure of data sent and received.
- Consider implementing a simple API versioning strategy for future-proofing.
- Handle potential CORS issues when communicating with the backend.

Security:

- Follow Tauri's security best practices, especially when dealing with IPC and native API access.
- Implement proper input validation and sanitization on the frontend.
- Use HTTPS for all communications with external services.
- Implement proper authentication and authorization mechanisms if required.
- Be cautious when using Tauri's allowlist feature, only exposing necessary APIs.

Performance Optimization:

- Optimize Svelte components for efficient rendering and updates.
- Use lazy loading for components and routes where appropriate.
- Implement proper caching strategies for frequently accessed data.
