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(process.env.PORT ?? 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(); const httpServer = http.createServer(server).listen(3000); const httpsServer = https.createServer(httpsOptions, server).listen(443); Because we called http.createServer / https.createServer ourselves, NestJS doesn't close them when calling app.close / on termination signal. We need to do this ourselves:
@Injectable() export class ShutdownObserver implements OnApplicationShutdown { private httpServers: http.Server[] = []; public addHttpServer(server: http.Server): void { this.httpServers.push(server); } public async onApplicationShutdown(): Promise<void> { await Promise.all( this.httpServers.map( (server) => new Promise((resolve, reject) => { server.close((error) => { if (error) { reject(error); } else { resolve(null); } }); }), ), ); } } const shutdownObserver = app.get(ShutdownObserver); shutdownObserver.addHttpServer(httpServer); shutdownObserver.addHttpServer(httpsServer); Hint TheExpressAdapteris imported from the@nestjs/platform-expresspackage. Thehttpandhttpspackages are native Node.js packages.
Warning This recipe does not work with GraphQL Subscriptions.
