Learn Elixir by Building a Real Time CLI Chat App (Part 3)
summary
Builds a fully distributed CLI chat app using core Elixir/OTP primitives and shows how it actually works: GenServer/Task/spawn-based processes, GenServer, message passing with timeouts, and supervision trees for fault recovery. Demonstrates runtime inspection with observer, spawns ~100000 processes on a laptop and claims hotspots up to ten million, shows restarting children and simple looping counters, and wires real networked CLI messaging so the app runs end to end.
