tauri-plugin-orpc

Tauri v2 plugin for serving oRPC routers via IPC.

Overview

Replaces HTTP transport with Tauri's native IPC, enabling zero-network-overhead RPC in desktop apps. Supports both request-response and streaming subscriptions via Tauri's Channel API.

Rust Setup

// src-tauri/src/lib.rs
tauri::Builder::default()
    .plugin(tauri_plugin_orpc::init(router, |app_handle| AppCtx {
        db: db.clone(),
    }))
    .run(tauri::generate_context!())
    .unwrap();

How It Works

Registers a single IPC command plugin:orpc|handle_rpc that auto-detects procedure type:

Single-value (query/mutation): Returns JSON response directly
Subscription (stream): Spawns a background task, streams events via Channel, returns immediately

Permissions

Add "orpc:default" to your Tauri capabilities:

{
  "permissions": ["core:default", "orpc:default"]
}
