RIG - Reactive Interaction Gateway

Makes frontend<->backend communication reactive and event-driven.

About

The Reactive Interaction Gateway (RIG) is the glue between your client (frontend) and your backend. It makes communication between them easier by (click the links to learn more)

• picking up backend events and forwarding them to clients based on subscriptions: this makes your frontend apps reactive and eliminates the need for polling. You can do this
  • asynchronously - using Kafka, Nats or Kinesis.
  • synchronously - if you don't want to manage a (potentially complex) message broker system like Kafka.
• forwarding client requests to backend services either synchronously, asynchronously or a mix of both:
  • synchronously - if requests are being sent synchronously, RIG acts as a reverse proxy: RIG forwards the request to an HTTP endpoint of a backend service, waits for the response and sends it to the client.
  • asynchronously - fire&forget - RIG transforms a HTTP request to a message for asynchronous processing and forwards it to the backend asynchronously using either Kafka, NATS or Amazon Kinesis.
  • synchronously with asynchronous response - a pseudo-synchronous request: RIG forwards the client request to the backend synchronously via HTTP and waits for the backend response by listening to Kafka/NATS and forwarding it to the still open HTTP connection to the frontend.
  • asynchronously with asynchronous response - a pseudo-synchronous request: RIG forwards the client request to the backend asynchronously via Kafka or NATS and waits for the backend response by listening to Kafka/NATS and forwarding it to the still open HTTP connection to the frontend.

Built on open standards, RIG is very easy to integrate – and easy to replace – which means low-cost, low-risk adoption. Unlike other solutions, RIG does not leak into your application – no libraries or SDKs required. Along with handling client requests and publishing events from backend to the frontend, RIG provides many out-of-the-box features.

This is just a basic summary of what RIG can do. There is a comprehensive documentation available on our website. If you have any unanswered question, check out the FAQ section to get them answered.
