await! clj/s

(await! {:com.wsscode.async.processing/keys [request-id timeout
                                             request-response]
         :as msg})

Wait for some async response, this returns a channel that will receive the data once the other side responds to the ::request-id.

When message doesn't have a ::request-id this function is a noop, so its safe to call in the message return point of your code.

capture-response! clj/s

(capture-response! {:com.wsscode.async.processing/keys [response-id
                                                        request-response]})

Use this helper in the receiving side of events, right before sending to your original handler message. This will ensure that response messages are propagated back to the listener.

event-queue! clj/s

(event-queue! handler)

(event-queue! {:com.wsscode.async.processing/keys [channel]} handler)

Returns a callback handler that will respond to events in a serialized queue. When the user handler returns a channel, the next message will wait until the current one finished processing before moving on. Use this on callback handlers that need serialization to avoid concurrency issues.

random-request-id clj/s

(random-request-id)

Portable helper to generate random UUID.

reply-message clj/s

(reply-message {:com.wsscode.async.processing/keys [request-id]} value)

Helper to make a response map for a given message with a request-id.

Use this to generate response data from async events.
