Resgate - A Realtime API Gateway used with NATS to build REST, real time, and RPC APIs, where all your clients are synchronized seamlessly.

Resgate is a Go project implementing a realtime API gateway for the RES protocol with NATS server as messaging system. It is a simple server that lets you create REST, real time, and RPC APIs, where all your clients are synchronized seamlessly.

Resgate handles all API requests from your clients, instead of directly exposing your micro-services (represented by Node.js and Java below). Clients will connect to Resgate, using either HTTP or WebSocket, to make requests. These requests are sent to the micro-services over NATS server, and Resgate will keep track on which resource each client has requested. Whenever there is a change to the data, the responsible micro-service sends an event. Resgate will use this event to both update its own cache, and make sure each subscribing client is kept up-to-date.
