Phoenix LiveView (announcement) leverages the channels mechanism to provide real-time updates to server-rendered content in web applications. In my opinion, this is one of the best parts of Phoenix.

For those unfamiliar with LiveView, here's a quick synopsis from the README:

LiveView is server centric. You no longer have to worry about managing both client and server to keep things in sync. LiveView automatically updates the client as changes happen on the server.

LiveView is first rendered statically as part of regular HTTP requests, which provides quick times for "First Meaningful Paint", in addition to helping search and indexing engines.

Then LiveView uses a persistent connection between client and server. This allows LiveView applications to react faster to user events as there is less work to be done and less data to be sent compared to stateless requests that have to authenticate, decode, load, and encode data on every request.

LiveView reduces the overhead of JavaScript client-side frameworks and libraries, aside from a DOM diff/patch tool like morphdom.

With channels seemingly well underway, might it be time to add LiveView support either in the core as a library? I started this issue following this Twitter thread. I would be happy to work on this or help out in some way.
