Running wss in Nextjs

[hypo-thesis]

I was unable to find a work around to make my ws into wss on Nextjs. As on Express I can

const server = https.createServer({
  cert: fs.readFileSync('/www/wwwroot/domain/cert/cert.pem'),
  key: fs.readFileSync('/www/wwwroot/domain/cert/key.pem')
});
const wss = new Websocket.Server({ server })
server.listen(8082)

I do not know how to integrate the pem certificates in Nextjs.
ws works fine with nextjs but I am not sure how I can introduce the ssl to work with ws with nextjs.
Can you give me some direction to use wss intead of ws?

See https://nextjs.org/docs/advanced-features/custom-server. Replace const { createServer } = require('http') with const { createServer } = require('https') and use the options object as described here https://nodejs.org/api/https.html#https_https_createserver_options_requestlistener.
