Sometimes you may want to run a local server with the desktop app.
Actix is a good choice.
Here is sample code. You can run the server in a separate thread in setup.
```rust
use actix_web::dev::Server;
use std::error::Error;
use actix_web::{get, post, web, App, HttpResponse, HttpServer, Responder};
#[get("/")]
pub async fn index() -> impl Responder {
HttpResponse::Ok().body("App Name")
}
#[post("/echo")]
pub async fn echo(req_body: String) -> impl Responder {
HttpResponse::Ok().body(req_body)
}
pub fn run_server(port: u16) -> Result<Server, Box<dyn Error>> {
Ok(HttpServer::new(|| App::new().service(index).service(echo))
.bind(("0.0.0.0", port))?
.run())
}
pub fn start_server() -> Result<(), Box<dyn Error>> {
tauri::async_runtime::spawn(run_server(8000)?);
Ok(())
}
pub fn setup(app: &mut tauri::App) {
server::start_server().expect("Failed to start local server");
}
fn main() {
tauri::Builder::default()
.setup(|app| {
setup::setup(app);
Ok(())
})
.run(tauri::generate_context!())
.expect("error while running tauri application");
}
```
