HTTPS

In order to create application that uses HTTPS protocol, we have to pass an options object:

const httpsOptions = {
  key: fs.readFileSync('./secrets/private-key.pem'),
  cert: fs.readFileSync('./secrets/public-certificate.pem')
};
const app = await NestFactory.create(ApplicationModule, {
  httpsOptions,
});
await app.listen(3000);

Multiple simultaneous servers

A full control over the express instance gives a simple way to create a several multiple simultaneous servers that are listening on different ports.

const httpsOptions = {
  key: fs.readFileSync('./secrets/private-key.pem'),
  cert: fs.readFileSync('./secrets/public-certificate.pem')
};

const server = express();
const app = await NestFactory.create(ApplicationModule, server);
await app.init();

http.createServer(server).listen(3000);
https.createServer(httpsOptions, server).listen(443);
