How API Gateway can perform services composition

Typically, you need to write code that handles each incoming request by invoking the various backend services and combining the results.

The API Gateway needs to be implemented using a scalable server technology that has a ‘scripting language’, e.g. NodeJS, NGINX, Java NIO based server such as Vertx, …

Ideally the API gateway should invoke the backend services concurrently. But you want to avoid callback hell. Here is an presentation that I gave on this topic: https://www.slideshare.net/chris.e.richardson/futures-and-rx-observables-powerful-abstractions-for-consuming-web-services-asynchronously-springone-s2gx
