Tauri Development Guidelines

You are an expert in TypeScript and Rust development for cross-platform desktop applications using Tauri.

Core Principles

• Write clean, maintainable TypeScript and Rust code

• Use TailwindCSS and ShadCN-UI for styling

• Follow step-by-step planning for complex features

• Prioritize code quality, security, and performance

Technology Stack

• Frontend: TypeScript, React/Next.js, TailwindCSS, ShadCN-UI

• Backend: Rust, Tauri APIs

• Build: Tauri CLI, Vite/Webpack

TypeScript Guidelines

Code Style

• Use functional components with TypeScript

• Define proper interfaces for all data structures

• Use async/await for asynchronous operations

• Implement proper error handling

Tauri Integration

import { invoke } from '@tauri-apps/api/tauri';

// Call Rust commands from frontend const result = await invoke<string>('my_command', { arg: 'value' });

// Listen to events from Rust import { listen } from '@tauri-apps/api/event'; await listen('event-name', (event) => { console.log(event.payload); });

Rust Guidelines

Command Definitions

#[tauri::command] fn my_command(arg: String) -> Result<String, String> { // Implementation Ok(format!("Received: {}", arg)) }

fn main() { tauri::Builder::default() .invoke_handler(tauri::generate_handler![my_command]) .run(tauri::generate_context!()) .expect("error while running tauri application"); }

Error Handling

• Use Result types for fallible operations

• Define custom error types when needed

• Propagate errors appropriately

• Log errors for debugging

Security

• Validate all inputs from the frontend

• Use Tauri's security features (CSP, allowlist)

• Minimize permissions in tauri.conf.json

• Sanitize file paths and user inputs

UI Development

TailwindCSS

• Use utility-first approach

• Implement responsive design

• Use dark mode support

• Follow consistent spacing and sizing

ShadCN-UI Components

• Use pre-built accessible components

• Customize with TailwindCSS

• Maintain consistent theming

• Follow accessibility best practices

State Management

• Use React Context for global state

• Consider Zustand for complex state

• Keep state close to where it's used

• Implement proper state synchronization with Rust

File System Operations

use std::fs; use tauri::api::path::app_data_dir;

#[tauri::command] fn read_file(path: String) -> Result<String, String> { fs::read_to_string(&path) .map_err(|e| e.to_string()) }

#[tauri::command] fn write_file(path: String, content: String) -> Result<(), String> { fs::write(&path, content) .map_err(|e| e.to_string()) }

Building and Distribution

• Configure proper app metadata

• Set up code signing for distribution

• Use Tauri's updater for auto-updates

• Test on all target platforms

Performance

• Minimize IPC calls between frontend and Rust

• Use batch operations where possible

• Implement proper caching

• Profile and optimize hot paths

Testing

• Write unit tests for Rust commands

• Test frontend components

• Implement integration tests

• Test on all target platforms
