How do you create and consume WebSocket APIs using Akka HTTP? Can you provide a high-level overview of a possible use case?
To create and consume WebSocket APIs using Akka HTTP, follow these steps :
1. Define routes : Create a route that handles WebSocket requests using the handleWebSocketMessages directive.
2. Implement message handling : Use actors or flows to process incoming messages and generate responses.
3. Establish connection : Clients connect to the WebSocket API by sending an HTTP request with an “Upgrade” header.
Example use case : A real-time chat application can utilize Akka HTTP WebSockets for efficient communication between clients and server. The server defines a route for WebSocket connections, processes incoming text messages from clients, broadcasts them to all connected users, and sends acknowledgements back to the sender.
