Akka-HTTP-Akka-Streams-Akka-Actors-Integration is a Scala library typically used in Programming Style applications. Akka-HTTP-Akka-Streams-Akka-Actors-Integration has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

The JokeFetcher Akka Actor is used to continuously poll the ICNDB endpoint behind the scenes and publish each discrete JSON response onto the Event Stream as a JokeEvent. The JokePublisher Akka Actor is a point of integration between Akka Actors and Akka Streams. The JokePublisher is created whenever a request to the /streaming-jokes endpoint which in turn creates an Akka Stream to stream the response back to the requester. It lives for the duration of that Stream and gets terminated once the Stream completes (does not happen in this case because it is an infinite Stream) or when the Stream is cancelled (happens when the requester does not want anymore data). As you can see the JokePublisher is tied to the duration of each Stream. This means if 6 users come in and request data from /streaming-jokes then 6 actors of JokePublisher will be created, each of them will be responsible for publishing data into that specific user's streaming response. The JokePublisher on creation, will subscribe to the Akka EventStream and listen for JokeEvents and send them downstream to provide streaming responses. As you can see, publishing messages to the JokePublisher Actor will end up in the Akka Stream which is why this is a point of integration between Akka Actors and Akka Streams when it comes to publishing data into the Akka Stream. This actor respects backpressure. It will only send information as fast as the downstream consumer can consume. It will drop messages if they are coming in too quickly. Users can hit the /streaming-jokes route in order to get back an SSE streaming JSON response of Chuck Norris jokes in JSON format.
