Hi, I’m George Arrowsmith - you may remember me from such educational Elixir content as Phoenix on Rails.

I’m really pleased to announce my new course. Learn Phoenix LiveView is the comprehensive tutorial that teaches you how to build a realistic, complex, fully-featured LiveView app from scratch.

Like Phoenix on Rails, it’s a written tutorial. Unlike Phoenix on Rails, it’s for everybody, not just Rails developers. It’s suitable for the total Phoenix beginner, so it covers the full stack including Ecto, not just LiveView UIs.

I designed this course to be realistic. There’s no “foo”, no “bar”, no “widgets” - you’ll build a realistic and fully-featured Slack clone. Along the way you’ll be introduced to every LiveView concept I could think of: if you can build this in LiveView, you can build anything.
