Read and watch tutorials: Thinking Elixir - a podcast that explores different aspects of the Elixir programming language: https://thinkingelixir.com/ Learn Elixir - a free interactive tutorial that teaches Elixir from scratch: https://www.learnelixir.tv/ Programming Phoenix LiveView - a book that teaches how to build web applications in Elixir using the Phoenix framework https://pragprog.com/titles/liveview/programming-phoenix-liveview/

A good project based book that goes pretty in depth is: https://pragprog.com/titles/liveview/programming-phoenix-liv...

LiveView is evolving into a great piece of tech, but as others have noted elsewhere in the comments one of the challenging parts with LiveView right now (and to an extent Phoenix) is the outdated books & tutorials.

Bruce Tate and Sophie DeBenedetto have been authoring the book “Programming Phoenix LiveView” (https://pragprog.com/titles/liveview/programming-phoenix-liv...) which has the potential to be a great source for people that want to really dive into LiveView. The challenge though is they have not updated it to support the changes introduced in 0.18.0 which makes it really hard to start using the book when a new Phoenix application “mix phx.new dev_app” looks different than what’s in their book and some of their code breaks with the default installed versions of included plugs.

While I wish the book would receive an update sooner that brings it back to a compatible state (meaning there are no issues following along with the book), the good news is they have committed to having the book be updated when LiveView hits 1.0.

I suggest cloning down an actual LiveView project (maybe this one?) and making changes to it. That will help you get a grip on things more easily than trying to build something from scratch right away.

All web frameworks fail with forms one way or the other :)

I think one point would be the docs, to outline the basic cases, best practices. Maybe something tying the form helpers and changeset.

I have a side project [0] with a form which have inputs dependant of others and a dynamic section (assoc).

I struggled a bit with the data, checking what I would get inside a changeset struct, until I "discovered" get_field and put_change.

For the assoc I was also a bit lost until I read an article using a delete virtual field. In the end I made it work but I still not sure I used all the right changeset functions.

To LiveView credits this app has been used all over the world and got very good feedback, nobody mentioned any lag issue etc (well, someone with a crappy connexion in Istanbul once got an incomplete uploaded file without getting an error).

Hello, this is a LiveView app (although most of the player code is in javascript).
