I wrote it according to the example in the HTTP/2 document. It did not make a mistake, but when I visited localhost:8443, the browser returned: "localhost did not send any data."

I found on npm that the http2 module has been deprecated. Is it caused by this? Is there any alternative? Because I’m learning node recently, the HTTP2 described in the book supports multiplexing, header compression, service push and other features, which can reduce a lot of overhead, which is very important to me.

You may have to visit with URL https://localhost:8443 (there may be a privacy error, since a self-signed certficate are used in the demo. You could trust the certificate temporarily to see what will happen).

No, http2 is a built-in module of Node.js, and is not related to http2 on npm.
