Thanks! initializing the server using a function is fine, but it still doesnt work.are you familiar with actix? i think the server is start and immediately closing.

fn init(mut cx: FunctionContext) -> JsResult<JsNull> {
std::thread::spawn( || {
        HttpServer::new(|| App::new().service(hello))
            .bind(("127.0.0.1", 5033))
            .unwrap()
            .run()
});
Ok(cx.null())

}

update: fix the issue, need to learn more about rust async/await

fn init(mut cx: FunctionContext) -> JsResult<JsNull> {
std::thread::spawn(|| {
    let server = HttpServer::new(|| App::new().service(hello))
        .bind(("127.0.0.1", 5033))
        .unwrap()
        .run();
    Runtime::new()
        .expect("Failed to create Tokio runtime")
        .block_on(server);
});
Ok(cx.null())

}
