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.
