HTTPS

To create an application that uses the HTTPS protocol, set the httpsOptions property in the options object passed to the create() method of the NestFactory class:

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

If you use the FastifyAdapter, create the application as follows:

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

Multiple simultaneous servers

The following recipe shows how to instantiate a Nest application that listens on multiple ports (for example, on a non-HTTPS port and an HTTPS port) simultaneously.

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

const server = express();
const app = await NestFactory.create(
  AppModule,
  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. The http and https packages are native Node.js packages.
