Using the .iex.exs File for Simplified IEx Sessions

When developing an application in Elixir, IEx (the interactive shell) can be enhanced with the .iex.exs file, which is executed each time IEx is initiated. This file allows developers to set up aliases and imports automatically, saving time during development. For example, by including aliases for modules like Teacher.Repo and Teacher.Recordings in .iex.exs, you can simplify commands in your IEx sessions. This customization makes it easier to write and test queries, improving the workflow significantly. Furthermore, developers can add informative messages to display when starting a session, making the environment more user-friendly.
