Intro
You already know the hardest part — BEAM and OTP. Elixir simply gives you more places to apply that knowledge. This book is a step-by-step migration guide for Erlang/OTP developers moving into the wider Elixir ecosystem: Web with Phoenix and LiveView, Data with Ecto and Broadway, Edge computing with Nerves and AtomVM, and AI with Nx, Axon, and Bumblebee.
The premise is simple: Erlang/OTP provides the foundation; Elixir builds on it. Both languages compile to the same BEAM bytecode and share the same OTP libraries — only the syntax and tooling differ. You don't replace Erlang; you extend its reach.
Through 29 chapters across six parts, you'll translate your skills into idiomatic Elixir, explore the ecosystem's flagship libraries, run AI models without Python, and finish with an 8-week migration roadmap plus deep dives into processes, GenServers, supervision, and pattern matching.
Every chapter pairs "From Erlang you know" boxes with hands-on Step-by-step blocks and checkpoints — because the fastest way to learn Elixir is by running it.
