How to create https server and support wss use koa2? I need it very much.

http + https =

const Koa = require('koa');
const app = new Koa();
http.createServer(app.callback()).listen(80);
const options = {
    key: fs.readFileSync('./ssl/private.pem', 'utf8'),
    cert: fs.readFileSync('./ssl/20180303.crt', 'utf8')
};
https.createServer(options, app.callback()).listen(443);

http + ws =

const Koa = require('koa');
const websockify = require('koa-websocket');
const app = websockify(new Koa());
app.listen(80);

https + wss = ?

[saurabh-codeword]

you can do it this way:

const server = new Koa();

// ... middlewares and routes

const options = {
   // Local certificates, if you don;t have them generate from mkcert or letsEncrypt
    key: fs.readFileSync("localhost-key.pem"),
    cert: fs.readFileSync("localhost.pem")
  };

  https.createServer(options, server.callback()).listen(port);

In anyway, you can perfectly stick with HTTP on the Koa side and use a reverse-proxy (nginx, httpd) to enable HTTPS — I think most people use Koa this way (at least I use Koa this way).
