## How to Use This Repository
|
||||||
|
|
||||||
|
### For LLMs / AI Agents
|
||||||
|
|
||||||
|
This repository is designed to be **searched directly**. When you receive a Tauri 2.0 question, use the table below to locate the most relevant document, then read the specific section referenced.
|
||||||
|
|
||||||
|
**Important constraints for agents:**
|
||||||
|
- You **cannot compile or run code** in a sandbox. Verify correctness using logic, API pattern matching, and cross-referencing these documents.
|
||||||
|
- All code in this repository is **Tauri 2.0 only** — do NOT use v1 patterns (see the migration section in `definitive-guide.md` for the full v1-to-v2 diff).
|
||||||
|
- Every plugin requires 4 things: (1) Rust crate in `Cargo.toml`, (2) `.plugin()` registration in the Builder, (3) npm package, (4) permissions in capabilities.
|
||||||
|
|
||||||
|
### For Developers
|
||||||
|
|
||||||
|
Use the **Definitive Guide** (`tauri2-guide/definitive-guide.md`) as your primary reference. It covers every aspect of Tauri 2.0 development end-to-end. For specific tasks, use the **Agent Prompts** as templates. For debugging, search the **Error Resolution Guide** by error message.

## Key Tauri 2.0 Concepts (Quick Orientation)
|
||||||
|
|
||||||
|
### The v1 vs v2 Difference — Critical
|
||||||
|
|
||||||
|
Tauri 2.0 is a **complete rewrite**, not an incremental update. The most common mistake is using v1 API patterns in a v2 project. The most frequently violated rules:
|
||||||
|
|
||||||
|
| Area | v1 (WRONG in v2) | v2 (Correct) |
|
||||||
|
|------|-------------------|---------------|
|
||||||
|
| Window type | `tauri::Window` | `tauri::WebviewWindow` |
|
||||||
|
| Window builder | `tauri::WindowBuilder` | `tauri::WebviewWindowBuilder` |
|
||||||
|
| Window URL | `tauri::WindowUrl` | `tauri::WebviewUrl` |
|
||||||
|
| Get window | `get_window("main")` | `get_webview_window("main")` |
|
||||||
|
| JS invoke import | `@tauri-apps/api/tauri` | `@tauri-apps/api/core` |
|
||||||
|
| JS window import | `@tauri-apps/api/window` | `@tauri-apps/api/webviewWindow` |
|
||||||
|
| Plugin JS imports | `@tauri-apps/api/<name>` | `@tauri-apps/plugin-<name>` |
|
||||||
|
| Config app section | `tauri` key | `app` key |
|
||||||
|
| Config dist dir | `build.distDir` | `build.frontendDist` |
|
||||||
|
| Security model | `allowlist` in config | Capabilities + Permissions (ACL) |
|
||||||
|
| Core logic file | `main.rs` only | `lib.rs` + `main.rs` pattern |
|
||||||
|
| Event emit | `window.emit()` | `app.emit()` (global) / `app.emit_to()` (targeted) |
|
||||||
|
| Rust APIs | `tauri::api::*` modules | Everything moved to plugins |
|
||||||
|
|
||||||
|
**Full migration map**: See `tauri2-guide/agent-prompts.md` Section 14 (v1 vs v2 API Map).
|
||||||
|
|
||||||
|
### The 4-Step Plugin Pattern
|
||||||
|
|
||||||
|
Every Tauri 2.0 plugin requires all four steps:
|
||||||
|
|
||||||
|
1. **Rust crate** — Add `tauri-plugin-<name> = "2"` to `src-tauri/Cargo.toml`
|
||||||
|
2. **Registration** — Add `.plugin(tauri_plugin_<name>::init())` in the `tauri::Builder`
|
||||||
|
3. **JS package** — `npm install @tauri-apps/plugin-<name>`
|
||||||
|
4. **Permissions** — Add permission identifiers (e.g., `fs:default`) to `src-tauri/capabilities/default.json`
|
||||||
|
|
||||||
|
### The Project Structure Pattern
|
||||||
|
|
||||||
|
```
|
||||||
|
src/ → Frontend UI (HTML/CSS/JS or any framework)
|
||||||
|
src-tauri/ → Rust backend
|
||||||
|
src/main.rs → Minimal desktop entry-point (calls lib::run())
|
||||||
|
src/lib.rs → Core app logic, Builder, commands, setup
|
||||||
|
src/<modules>.rs → Additional Rust modules
|
||||||
|
capabilities/ → Security capability JSON files
|
||||||
|
tauri.conf.json → Main config (v2 schema)
|
||||||
|
Cargo.toml → Rust dependencies
|
||||||
|
build.rs → Tauri build script
|
||||||
|
```
|
||||||
|
|
||||||
|
### The Command Pattern
|
||||||
|
|
||||||
|
```rust
|
||||||
|
#[tauri::command]
|
||||||
|
async fn my_command(name: String) -> Result<String, String> {
|
||||||
|
Ok(format!("Hello, {}!", name))
|
||||||
|
}
|
||||||
|
|
||||||
|
// Register in Builder (single invoke_handler call only):
|
||||||
|
.invoke_handler(tauri::generate_handler![my_command])
|
||||||
|
```
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
// Frontend invocation
|
||||||
|
import { invoke } from '@tauri-apps/api/core';
|
||||||
|
const result = await invoke('my_command', { name: 'World' });
|
||||||
|
```
|
||||||
|
|
||||||

## Search Tips for LLMs
|
||||||
|
|
||||||
|
When looking for information in this repository, search for these keywords and patterns:
|
||||||
|
|
||||||
|
- **Error messages**: Search the exact error string (e.g., `"unresolved import tauri::api"`, `"command not found"`, `"not allowed"`) in `error-resolution-guide.md`
|
||||||
|
- **API names**: Search for type names (e.g., `WebviewWindowBuilder`, `Emitter`, `Channel`) in `definitive-guide.md`
|
||||||
|
- **Config keys**: Search for JSON key names (e.g., `frontendDist`, `withGlobalTauri`, `capabilities`) in `definitive-guide.md` Section 3
|
||||||
|
- **Plugin names**: Search for plugin identifiers (e.g., `tauri-plugin-fs`, `plugin-dialog`, `store:default`) in `definitive-guide.md` Section 9
|
||||||
|
- **Migration**: Search for old v1 names (e.g., `WindowBuilder`, `allowlist`, `@tauri-apps/api/tauri`) to find their v2 replacements
|
||||||
|
- **Patterns**: Search for pattern keywords (e.g., `initialization_script`, `run_on_main_thread`, `broadcast channel`, `include_str`) in both `definitive-guide.md` and `ws_server_client_inject_guide.md`
|
||||||
|
- **Permission identifiers**: Search for permission strings (e.g., `core:event:allow-listen`, `fs:allow-read`, `http:default`) in `definitive-guide.md` Section 4 and `error-resolution-guide.md` Category E
