Phoenix: an Intro to Elixir's Web Framework
summary
Demonstrates building a small Phoenix app live: generating a project with mix, wiring Plug/Cowboy as the HTTP layer, using Ecto changesets for form validation and DB inserts, and rendering templates with embedded Elixir. Adds session-based login, a plug that assigns current_user, and a registration flow that actually persists and redirects. Implements realtime chat with Phoenix Channels & Presence, pushing message history on join and broadcasting new messages to all subscribers via PubSub with a phoenix.js client in the browser.
