Creating a Deno https server

Question

I am looking for an example of creating a https server in Deno. I have seen examples of Deno http server but not https.

I have tried searching in google but found no results

Answer 1

With Deno 1.9+ you could use the native server. It provides the ability to use HTTPS.

It is a good bit faster faster than older implementations of std/http. However, as of version 0.107.0 the native server is used for std/http as well.

Example:

const server = Deno.listenTls({
  port: 443,
  certFile: "./my-ca-certificate.pem",
  keyFile: "./my-key.pem"
});

for await (const conn of server) {
  handle(conn);
}

async function handle(conn: Deno.Conn) {
  const httpConn = Deno.serveHttp(conn);
  
  for await (const requestEvent of httpConn) {
    try {
      const response = new Response("Hello World!");
      await requestEvent.respondWith(response);
    } 
    catch (error) {
      console.error(error);
    }
  }
}

Answer 2

serveTLS has landed along with Deno 0.23.0:

Sample usage:

import { serveTLS } from "https://deno.land/std/http/server.ts";

const body = new TextEncoder().encode("Hello HTTPS");
const options = {
  hostname: "localhost",
  port: 443,
  certFile: "./path/to/localhost.crt",
  keyFile: "./path/to/localhost.key",
};
// Top-level await supported
for await (const req of serveTLS(options)) {
  req.respond({ body });
}
