    I haven’t delved too deep but this seems like GraphQL in a way.

      It can aggregate like GraphQL, but other features (like circuit breakers, web sockets, load balancing etc) aren’t covered by GraphQL. This is more like Ocelot, but simpler: http://threemammals.com/ocelot

      But your comment is puttng some ideas in my head; maybe GraphQL support is a feature I could add?

        I’m a fan of it, so why not? (:

      Hi, I’ve been working on this for the past three months. I started this project because many clients I work with (as part of my consulting gigs) have switched to Micro Services and needed an API gateway in front of them (to do response aggregation, rate limiting etc). There are options out there like Kong, but some of them prefer a simpler (and free) tool extensible using JS. Hence Prism.

      Aside of regular API gateway features, some capabilities in Prism are unique. For instance, Prism can receive messages on Redis channels and forward them to specific WebSocket clients. This allows multiple services to asynchronously send messages to WebSocket clients.

      Prism is in Beta, but good enough to start trialing with. Over the next few weeks, I plan to add more tests and improve the documentation. In particular, the documentation around WebSockets needs more attention.

      Happy to handhold anyone who wants to try Retransmit. If you run into problems, please file an issue on github.
