Binding IP for a nest application is verbose

Hullo 👋

Currently if you want to bind your express instance to a specific IP you end up with something like this:

@Module({})
class ApplicationModule {}x

function createApp (
  server: express.Application,
  port: number,
  address: string
): Promise<INestApplication> {
  const app = NestFactory.create(ApplicationModule, server)
  app.init()

  return eventToPromise(server.listen(port, address), 'listening').then(
    () => app
  )
}

It would seem more ideal if NestApplication.listen() better reflected the options that ExpressAppliation.listen() takes? The above isn’t so ideal given that it doesn’t check if the nest application has already been initialised.

@TobyColeman environment variables?

Hi @TobyColeman, Since @nestjs/core 4.0.4 the listen() method accepts hostname as a second argument 🙂
