How to listen on multiple ports with warp?

Question

warp::serve(routes)
    .run(([127, 0, 0, 1], 3030))
    .await;

How can I listen to different ports for http requests and websocket connection?

Answer 1

You can start two separate instances and run them concurrently:

tokio::join!(
    warp::serve(routes).run(([127, 0, 0, 1], 3030)),
    warp::serve(routes).run(([127, 0, 0, 1], 3031)),
);
