详细介绍
Tauri Rust/WASM 前端集成
本技能介绍如何将基于 Rust 的前端框架与 Tauri v2 集成,以使用 WASM 构建桌面和移动应用。
支持的框架
| 框架 | 描述 | 打包工具 |
|---|---|---|
| Leptos | 用于构建 Web UI 的响应式 Rust 框架 | Trunk |
| Yew | 基于组件的 Rust 框架 | Trunk |
| Dioxus | 跨平台 UI 框架 | Trunk |
| Sycamore | Rust 响应式库 | Trunk |
所有 Rust/WASM 前端都使用 Trunk 作为打包工具/开发服务器。
关键要求
- 仅限静态站点生成(SSG) - Tauri 不支持基于服务器的解决方案(SSR)。请使用 SSG、SPA 或 MPA 方案。
- withGlobalTauri - 必须启用此选项,WASM 前端才能通过
window.__TAURI__和wasm-bindgen访问 Tauri API。 - WebSocket 协议 - 配置
ws_protocol = "ws",以便在移动开发中使用热重载。

配置文件
Tauri 配置(src-tauri/tauri.conf.json)
{
"build": {
"beforeDevCommand": "trunk serve",
"devUrl": "http://localhost:1420",
"beforeBuildCommand": "trunk build",
"frontendDist": "../dist"
},
"app": {
"withGlobalTauri": true
}
}
关键设置:
beforeDevCommand:在启动 Tauri 之前运行 Trunk 开发服务器devUrl:Trunk 提供前端服务的 URL(Leptos 默认为 1420,纯 Trunk 默认为 8080)beforeBuildCommand:在打包前构建 WASM 包frontendDist:已构建前端资源的路径withGlobalTauri:WASM 必需 - 暴露window.__TAURI__以供访问 API
Trunk 配置(Trunk.toml)
[build]
target = "./index.html"
dist = "./dist"
[watch]
ignore = ["./src-tauri"]
[serve]
port = 1420
open = false
[serve.ws]
ws_protocol = "ws"
关键设置:
target:包含 Trunk 指令的 HTML 入口点ignore:避免监视 Tauri 后端的更改port:必须与 tauri.conf.json 中的devUrl相匹配open = false:阻止自动打开浏览器(由 Tauri 负责显示)ws_protocol = "ws":移动端热重载必需
前端 Cargo.toml(根目录)
[package]
name = "my-app-frontend"
version = "0.1.0"
edition = "2021"
[lib]
crate-type = ["cdylib", "rlib"]
[dependencies]
# Core WASM dependencies
wasm-bindgen = "0.2"
wasm-bindgen-futures = "0.4"
js-sys = "0.3"
web-sys = { version = "0.3", features = ["Window", "Document"] }
# Tauri API bindings for WASM
tauri-wasm = { version = "2", features = ["all"] }
# Choose your framework:
# For Leptos:
leptos = { version = "0.6", features = ["csr"] }
# For Yew:
# yew = { version = "0.21", features = ["csr"] }
# For Dioxus:
# dioxus = { version = "0.5", features = ["web"] }
[profile.release]
opt-level = "z"
lto = true
codegen-units = 1
panic = "abort"
关键设置:
crate-type = ["cdylib", "rlib"]:WASM 编译必需tauri-wasm:提供用于访问 Tauri API 的 Rust 绑定features = ["csr"]:为框架启用客户端渲染- 发布配置针对较小的 WASM 二进制体积进行了优化
HTML 入口点(index.html)
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>My Tauri App</title>
<link data-trunk rel="css" href="styles.css" />
</head>
<body>
<div id="app"></div>
<link data-trunk rel="rust" href="." data-wasm-opt="z" />
</body>
</html>
Trunk 指令:
data-trunk rel="css":包含 CSS 文件data-trunk rel="rust":将 Rust crate 编译为 WASMdata-wasm-opt="z":针对体积进行优化
Leptos 设置
Leptos 专用 Cargo.toml
[package]
name = "my-leptos-app"
version = "0.1.0"
edition = "2021"
[lib]
crate-type = ["cdylib", "rlib"]
[dependencies]
leptos = { version = "0.6", features = ["csr"] }
wasm-bindgen = "0.2"
wasm-bindgen-futures = "0.4"
console_error_panic_hook = "0.1"
tauri-wasm = { version = "2", features = ["all"] }
[profile.release]
opt-level = "z"
lto = true
Leptos 主入口(src/main.rs)
use leptos::*;
mod app;
use app::App;
fn main() {
console_error_panic_hook::set_once();
mount_to_body(|| view! { <App /> });
}
Leptos 应用组件(src/app.rs)
use leptos::*;
use wasm_bindgen::prelude::*;
use wasm_bindgen_futures::spawn_local;
#[wasm_bindgen]
extern "C" {
#[wasm_bindgen(js_namespace = ["window", "__TAURI__", "core"])]
async fn invoke(cmd: &str, args: JsValue) -> JsValue;
}
#[component]
pub fn App() -> impl IntoView {
let (message, set_message) = create_signal(String::new());
let greet = move |_| {
spawn_local(async move {
let args = serde_json::json!({ "name": "World" });
let args_js = serde_wasm_bindgen::to_value(&args).unwrap();
let result = invoke("greet", args_js).await;
let greeting: String = serde_wasm_bindgen::from_value(result).unwrap();
set_message.set(greeting);
});
};
view! {
<main>
<h1>"Welcome to Tauri + Leptos"</h1>
<button on:click=greet>"Greet"</button>
<p>{message}</p>
</main>
}
}
替代方案:使用 tauri-wasm crate
use leptos::*;
use tauri_wasm::api::core::invoke;
#[component]
pub fn App() -> impl IntoView {
let (message, set_message) = create_signal(String::new());
let greet = move |_| {
spawn_local(async move {
let result: String = invoke("greet", &serde_json::json!({ "name": "World" }))
.await
.unwrap();
set_message.set(result);
});
};
view! {
<main>
<button on:click=greet>"Greet"</button>
<p>{message}</p>
</main>
}
}
Tauri 后端命令
在 src-tauri/src/main.rs 中:
#[tauri::command]
fn greet(name: &str) -> String {
format!("Hello, {}! You've been greeted from Rust!", name)
}
fn main() {
tauri::Builder::default()
.invoke_handler(tauri::generate_handler![greet])
.run(tauri::generate_context!())
.expect("error while running tauri application");
}
开发命令
# Install Trunk
cargo install trunk
# Add WASM target
rustup target add wasm32-unknown-unknown
# Development (runs Trunk + Tauri)
cd src-tauri && cargo tauri dev
# Build for production
cd src-tauri && cargo tauri build
# Trunk only (for frontend debugging)
trunk serve --port 1420
# Build WASM only
trunk build --release
移动开发
移动平台需要额外配置:
移动端 Trunk.toml
[serve]
port = 1420
open = false
address = "0.0.0.0" # Listen on all interfaces for mobile
[serve.ws]
ws_protocol = "ws" # Required for mobile hot-reload
移动端 tauri.conf.json
{
"build": {
"beforeDevCommand": "trunk serve --address 0.0.0.0",
"devUrl": "http://YOUR_LOCAL_IP:1420"
}
}
将 YOUR_LOCAL_IP 替换为你机器的本地 IP(例如 192.168.1.100)。
从 WASM 访问 Tauri API
方法 1:直接使用 wasm-bindgen(推荐,便于控制)
use wasm_bindgen::prelude::*;
use serde::{Serialize, Deserialize};
#[wasm_bindgen]
extern "C" {
// Core invoke
#[wasm_bindgen(js_namespace = ["window", "__TAURI__", "core"], catch)]
async fn invoke(cmd: &str, args: JsValue) -> Result<JsValue, JsValue>;
// Event system
#[wasm_bindgen(js_namespace = ["window", "__TAURI__", "event"])]
async fn listen(event: &str, handler: &Closure<dyn Fn(JsValue)>) -> JsValue;
#[wasm_bindgen(js_namespace = ["window", "__TAURI__", "event"])]
async fn emit(event: &str, payload: JsValue);
}
// Usage
async fn call_backend() -> Result<String, String> {
let args = serde_wasm_bindgen::to_value(&serde_json::json!({
"path": "/some/path"
})).map_err(|e| e.to_string())?;
let result = invoke("read_file", args)
.await
.map_err(|e| format!("{:?}", e))?;
serde_wasm_bindgen::from_value(result)
.map_err(|e| e.to_string())
}
方法 2:使用 tauri-wasm crate
use tauri_wasm::api::{core, event, dialog, fs};
// Invoke command
let result: MyResponse = core::invoke("my_command", &my_args).await?;
// Listen to events
event::listen("my-event", |payload| {
// Handle event
}).await;
// Emit events
event::emit("my-event", &payload).await;
// File dialogs
let file = dialog::open(dialog::OpenDialogOptions::default()).await?;
// File system (requires permissions)
let contents = fs::read_text_file("path/to/file").await?;
故障排除
WASM 未加载
- 确认 tauri.conf.json 中的
withGlobalTauri: true - 检查浏览器控制台中的 WASM 错误
- 确保已安装
wasm32-unknown-unknown目标
移动端热重载无法运行
- 在 Trunk.toml 中设置
ws_protocol = "ws" - 设置
address = "0.0.0.0"以便移动设备访问 - 确认防火墙允许通过开发端口连接
Tauri API 未定义
withGlobalTauri必须为true- 在浏览器控制台中检查
window.__TAURI__是否存在 - 确认 tauri-wasm 版本与 Tauri 版本相匹配
WASM 二进制体积过大
- 启用发布配置优化
- 使用
opt-level = "z"优化体积 - 使用
lto = true启用 LTO - 考虑使用
wasm-opt进行后处理
Trunk 构建失败
- 检查 Cargo.toml 是否包含
crate-type = ["cdylib", "rlib"] - 确认 index.html 中的
data-trunk指令正确 - 确保未在框架中启用服务端功能
版本兼容性
| 组件 | 版本 |
|---|---|
| Tauri | 2.x |
| Trunk | 0.17+ |
| Leptos | 0.6+ |
| wasm-bindgen | 0.2.x |
| tauri-wasm | 2.x |
请始终确保 tauri-wasm 版本与 Tauri 版本匹配。
