As a reminder, LiveView is an in-development feature of the Phoenix web framework that helps you create rich, interactive experiences while writing very little (ostensibly, zero) JavaScript. In Chris’ words:

Phoenix LiveView is an exciting new library which enables rich, real-time user experiences with server-rendered HTML. LiveView powered applications are stateful on the server with bidrectional communication via WebSockets, offering a vastly simplified programming model compared to JavaScript alternatives.

In the linked post, Chris shows a lot of examples of LiveView in action, demonstrating what it’s capable of.

Here’s a feature-complete snake game, in 330 LOC, which requires zero user-land JavaScript.

Impressive!
