lily
Lily is a web framework for live server updates and offline interactivity. This was made since I was running into issues within Phoenix LiveView when combining real-time updates with offline-interactivity where needed. Instead of a VDOM, Lily allows components to dictate how/when they should be rendered.
Lily is designed to be modular, with each part replaceable by your own implementation. The browser facing modules are designed to be JS-only, and any server-based modules will have both a JS and Erlang implementation. That said, I would recommend using the Erlang/BEAM compilation target on the backend to get the full benefits of the BEAM VM.
Note that Lily is still under development, with breaking changes expected quite regularly at this stage.
