Hot Reload Axum

I got tired of restarting my shuttle run server pretty fast. I needed a solution.

Dug around a bit and found tower_livereload. It was actually mentioned in the shuttle docs here.

That isn't enought tho. You actually need one more piece. A more important piece i might add. cargo watch

This crate will auto reload your server on save, combined with tower livereload will also refresh the page, so you dont have to do anythign but wait, really.

Show me the important stuff

Install cargo watch

cargo install cargo-watch

Add Tower livereload

cargo add tower-livereload

Inject the necessary code in your project

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let app = Router::new()
        .route() // some route
        .layer(tower_livereload::LiveReloadLayer::new()); // <--- add here

    // --- ignore all of this ---v
    let listener = tokio::net::TcpListener::bind("0.0.0.0:8000").await?;
    axum::serve(listener, app).await?;

    Ok(())
}

Run your shuttle server in watch mode

# This will e(x)ecute `cargo shuttle run` when you save a file.
cargo watch -x 'shuttle run'
# This will also (q)uietly (c)lear the console between runs.
cargo watch -qcx 'shuttle run'

# There are many other helpful options, see `cargo watch --help`
