IEx, Elixir’s interactive shell, is a powerful tool hiding in plain sight. Even after years of daily use, I keep uncovering features that make development faster, debugging smoother, and exploration more fun.

In this talk, you’ll learn how to level up your IEx workflow—from improving multi-line history and input, to building your own helper functions, to recovering gracefully from half-baked commands, to making your .iex.exs available to remote shells. Even if you’ve been using IEx for a while, you’ll walk away with practical techniques and lesser-known features that can help you get even more out of your day-to-day Elixir development.
