Nest: How do you set up SSL?

[Kurdiez]

Is there a way to start the Nest application with SSL cert options so I can have a HTTPS server?

For now I manually call the init() function on the Nest app and start the HTTPS server with express app manually.

let options = {
    key: fs.readFileSync(Config.SSL_KEY_PATH),
    cert: fs.readFileSync(Config.SSL_CERT_PATH)
};

let httpsServer = https.createServer(options, expressApp);

const app = NestFactory.create(ApplicationModule, expressApp);
app.useGlobalPipes(new ValidatorPipe());
app.init();

httpsServer.listen(httpsPort);

I was just wondering if there is any standard way of doing SSL with Nest. Couldn't find it in the documentation.

Hey @jiminssy,
Yep, that's why the init() method exists. Your solution is the example how to use HTTPS, there's no other option right now.

For me was enough this code in the main.ts:

async function bootstrap() {
  const fs = require('fs');
  const keyFile  = fs.readFileSync(__dirname + '/../ssl/mydomain.com.key.pem');
  const certFile = fs.readFileSync(__dirname + '/../ssl/mydomain.com.crt.pem');

  const app = await NestFactory.create(AppModule, {
    httpsOptions: {
      key: keyFile,
      cert: certFile,
    }});

//...
}

Thanks @camposmiguel for the above answer. If I wish to run it locally on my machine over https, then how can i generate the key and crt certificates? I know this may sound trivial, but I am new to this party

It's possible to generate a Let' encrypt free certificate to use in localhost. Here you have the Let's Encrypt documentation: https://letsencrypt.org/docs/certificates-for-localhost/
