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);

If using Fastify create the app like this:

const app = await NestFactory.create<NestFastifyApplication>(
  ApplicationModule,
  new FastifyAdapter({ https: httpsOptions }),
);

Multiple simultaneous servers

A full control over the library 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,
  new ExpressAdapter(server),
);
await app.init();
http.createServer(server).listen(3000);
https.createServer(httpsOptions, server).listen(443);

info Hint The ExpressAdapter is imported from the @nestjs/platform-express package.
