Handling WebSocket connections and disconnections
When a client establishes a WebSocket connection with a FastAPI server, it’s crucial to handle the lifecycle of these connections appropriately. This includes accepting incoming connections, maintaining active connections, and handling disconnections gracefully to ensure smooth communication between the client and server. In this recipe, we’ll explore how to effectively manage WebSocket connections and gracefully handle disconnections.
Getting ready
To follow the recipe, you will need to have Postman or any other tool to test WebSocket connections. Also, you need to already have a WebSocket endpoint implemented in your application. Check the previous two recipes if that is not the case.
How to do it…
We will see how to manage the following two situations:
- Client-side disconnection
- Server-side disconnection
Let’s have a look at each of these situations in detail.
