Interconecting reSolve to another system

Question

I need to connect to an API of another system via a RESTful interface that will be providing events via a websocket connection.

I am using a javascript library to do all the heavy lifting with this other system. I am interested as to the best way to join that system and reSolve.

For example, the other system deals with real-world events and when one these events occurs I want it to feed into reSolve to alter the state.

These events are handled through standard .on handlers.

The inverse is also required, I need to be able to send commands to this other system from reSolve.

My initial thoughts would be in a saga, but I'm unsure if that is the preferred way of doing things.

Thank you for any support you are able to offer.

Answer 1

As I understand, you have some process that reacts on events in the external system. On these events you can just send a command to reSolve app (a trivial command RECORD_EXTERNAL_EVENT that just stores a payload). Then you can use all other reSolve parts to react on such event within reSolve.

In the inverse scenario - when you send events to an external system - you can create a saga with some kind of "send event" side effect, as Anton suggested.
