Why trunk serve doesn't automaticly serve when saving file?

Question

I'm using trunk serve in my rust project in Windows, everything goes great and compiles and serves, but if I save the file, it doesn't automactly re-compile and serve.

I was expecting it to when I save any of the rust file it to compile and serve, I did trunk serve and tried trunk serve --watch (filepath).

Any fix?

Answer 1

some times native method fails, and theres an alternative approach to do it, and if it was written than there where a purpose to do it.

Install Rust and Cargo

install using Cargo(Binstall):
https://crates.io/crates/cargo-watch

cargo install cargo-watch

recompile when changes are detected:

cargo watch -x run

rebuild without running:

cargo watch -x build

ignore changes in a directory:

cargo watch -x run --ignore "directory u want to ignore/*"

to set up a server u can do this:

cargo new rust_server
cd rust_server

add warp to your Cargo.toml:

[dependencies]
warp = "0.3"

than in src/main.rs, set up a simple HTTP server:

use warp::Filter;

#[tokio::main]
async fn main() {
    let hello = warp::path!("hello" / "world")
        .map(|| warp::reply::html("Hello, World!"));

    warp::serve(hello)
        .run(([127, 0, 0, 1], 9000))
        .await;
}

and than use this:

cargo watch -x run
