Great question! Real-time web app development is all about keeping your UI in sync with server-side changes, as they happen. The key technologies involved are WebSockets, Server-Sent Events (SSE) and HTTP/2 Server Push.

I couldn't agree more, John! I've personally used Socket.IO for Node.js and it's fantastic. It uses WebSockets under the hood to provide real-time connectivity.

Socket.IO support in the browser isn't perfect, though. You'll face connection drop issues which can be mitigated using techniques like auto-reconnect and binary reconnection.

Thanks, John, good to know! Which auto-reconnect libraries would you recommend?
john_doe 1 year ago prev next
There are several client-side libraries for handling Socket.IO auto-reconnect. I personally like socket.io-client for browser and socket.io for Node.js applications.

Thanks, John! I'll give socket.io-client a try next time I work with Socket.IO.

ActionCable is Rails' solution for WebSocket-powered real-time features. It bundles a JavaScript driver for WebSocket, a server-side Ruby component, and a router. It's super useful.

When building complex real-time applications, I prefer to use a library like GraphQL Subscriptions which allows real-time updates over WebSockets, and works seamlessly with GraphQL.

GraphQL Subscriptions supports subscriptions via WebSocket, falling back to HTTP polling if WebSocket is not supported on the client.

For simple real-time updates, Server-Sent Events can be a powerful tool, which is easier to implement compared to WebSocket and Socket.IO.

From the UI perspective, building reactive UI components provides a seamless user-experience for real-time apps. Check out libraries like React and Angular.
