Is there a document explaining what LiveView exactly do ? I mean which modifications are take into account and wich are not ?
I love to be able to change Alloy View in a second without re-deploying, but I am never sure of what I can modify and what I cant ?
So is there an official file list/type that works with LiveView ?
you can go through the repo:
and check yourself. There is a PR for a rewrite using Vite if I remember correctly. That should get some updates soon if everything goes well 
Basically it can send files that don’t need a recompile. Check liveview/fserver.js at master · tidev/liveview · GitHub for some of the watched folders. If it has the new files it will call a restart.
Still not get the reflex of looking on source code 
That does not matter it make forum content
