Building realtime applications with Rails has become a no-brainer since Action Cable came around. With Hotwire, we don’t even need to leave the comfort zone of HTML and controllers to introduce live updates to a Rails app. Realtime-ification in every house!

Switching to real-time hides many pitfalls you’d better learn beforehand. How to broadcast personalized data? How not to miss updates during connection losses? Who’s online? Does it scale?

Let me dig into these problems and demonstrate how to resolve them for Action Cable and Hotwire.

Building realtime features at scale is easy with the dedicated realtime server, AnyCable. It runs next to your main app (or, in our cloud) and handles realtime load, while ensuring the deliverability of messages and reliability of connections. Use powerful high-level abstractions to build chats, collaboration, IoT data features, gen-AI streaming, etc.
