Nest: Support for multiple simultaneous servers (e.g. HTTP and HTTPS)

[Jephery]

The current implementation of NestApplication.listen() does not support easily adding multiple Server backends, since it directly calls .listen() on the Express Application (which only creates an HTTP server).

At the very least, it would be helpful to add a public method on NestApplication that calls the setup functions (setupMiddleswares, setupRoutes, etc.) without calling express.listen().

For anyone else having this issue, a workaround is below:

const expressInstance = express();

const app = NestFactory.create(ApplicationModule, expressInstance);

app.listen(80, () => {
    console.log("HTTP server listening on port 80");
});

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

const httpsServer = https.createServer(httpsOptions);
httpsServer.addListener("request", expressInstance);
httpsServer.listen(443, () => {
    console.log("HTTPS server listening on port 443");
});

Hi @Jephery,
Since version 2.1.0 it is possible to directly call init() method on NestApplication instance. However, listen() method is backwards compatible. Example:

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

const server = express();
const app = NestFactory.create(ApplicationModule, server);
app.init();

http.createServer(server).listen(3000);
https.createServer(httpsOptions, server).listen(443);
