Trunk

Trunk is a WASM web application bundler for Rust. Learn more about Trunk at https://trunk-rs.github.io/trunk/. This guide is accurate as of Trunk 0.17.5.

Checklist

• Use SSG, Tauri doesn’t officially support server based solutions.
• Use serve.ws_protocol = "ws" so that the hot-reload websocket can connect properly for mobile development.
• Enable withGlobalTauri to ensure that Tauri APIs are available in the window.__TAURI__ variable and can be imported using wasm-bindgen.

Example Configuration

1. Update Tauri configuration

   {  "build": {    "beforeDevCommand": "trunk serve",    "beforeBuildCommand": "trunk build",    "devUrl": "http://localhost:8080",    "frontendDist": "../dist"  },  "app": {    "withGlobalTauri": true  }}

   tauri.conf.json

2. Update Trunk configuration

   [watch]ignore = ["./src-tauri"]
   [serve]ws_protocol = "ws"

   Trunk.toml
