✨This keynote talk was recorded at Code BEAM America 2024, a conference by Code Sync https://codebeamamerica.com ✨ Elixir embraces a fascinating mix of types, features, and libraries to build a surprising breadth of concurrent libraries and services with stunning reliability and concurrency. This talk allows a peek under the hood at how Nerves, LiveView, NX, LiveBook, and more push Elixir and yet provide a natural, coherent development experience. Behaviours in OTP establish contracts for inversion of control. Phoenix and LiveView take advantage of the same behaviours and also use macros to provide a uniform, concise usage model and adds macros to hide ceremony while surfacing beautiful user experience that remains correct under pressure, from templates to infrastructure Come find out how Elixir's most loved frameworks and tools got that way, and the Elixir tools that make those frameworks both beautiful and right.
