WebSockets for Real-Time Updates in Rust and React Admin | Glowing-Telegram Project - Episode 87
2In this video, I walk you through enhancing real-time capabilities in our Glowing-Telegram project by integrating WebSocket support. We focus on generating real-time task updates in a Rust backend and pushing those updates to a React Admin frontend without the need for continuous polling, ensuring a more responsive user experience. Let's dive into the key elements covered in this session and get our hands dirty with some code tweaks, debugging, and architectural decisions. Here's a detailed breakdown of what we accomplished today:
First, we start with a bit of housekeeping, updating some dependencies and making sure the environment is set up correctly. This included addressing some warnings and ensuring our Docker setup was functioning as expected.
Next, we review the changes made since our last stream and focus on Issue 33, which involves having task UI elements automatically check status updates using WebSockets. The goal is to avoid manual refreshes by implementing a server-client communication where the server pushes updates to the client.
We refactor our backend to handle WebSocket connections using the Tokio framework in Rust. This involved setting up a Redis Pub/Sub system where task updates are published through Redis and pushed to clients via WebSockets. We made several improvements to our task status update mechanism, including better error handling and result propagation.
In the frontend, using React and React Admin, we look at how we can leverage hooks and the context API to manage WebSocket connections. We discuss strategies for maintaining a single WebSocket connection to prevent redundant connections and ensure efficient state updates.
We implement a custom hook, 'useTaskStatusSubscription', which handles establishing a WebSocket connection, subscribing to task updates, and updating the React state accordingly. We explore using 'useReducer' for more complex state logic and discuss its benefits over 'useState'.
Throughout the video, we encounter various debugging scenarios, refactor code for clarity, and discuss design decisions, such as handling real-time updates and ensuring our code is maintainable and scalable.
