Low Latency LiveView

The article discusses the use of LiveView, a feature in Phoenix (a Rails-on-Elixir framework), to create real-time user experiences in web applications. It explains how HTML-over-websockets implementation works and highlights its benefits for server initiated changes. However, it also points out that latency can be an issue when users start interacting with the application. The article suggests three strategies to improve interaction response times: predicting new state client side, decreasing round trip time, and showing a loading indicator. It emphasizes the importance of moving app processes closer to users for faster responses and mentions how Fly.io can help deploy applications globally.
