In this post we go into the inner workings of how we can force our code to recompile when we have changes to external files or folders that the code is dependant on.

This past weekend, I added a feature to Flick (RankedVote.app) where we now present domain-specific DateTime values, like published_at and closed_at, on the live view page using the user’s time zone. I thought I’d capture some notes on how this was accomplished, some known limitations, ideas to solve those in your own work, and a set of resource links to learn more.

Discovery of using time zone in Ecto

Here’s a tutorial on how to translate Ecto changesets in Phoenix. It’s actually quite simple and you don’t even have to mix web and context concerns!

Let’s track and handle Tesla errors in your Elixir app using AppSignal: https://blog.appsignal.com/2025/01/21/tracking-errors-in-tesla-with-appsignal-for-elixir.html

Do you make similar changes to every project you begin in Elixir? So did I. That’s why I made a new Phoenix generator.

It defaults to UUIDs, sets all timestamps to utc_datetime_usec, and adds some common nice dependencies.

Sometimes, you’re running your application as a plain mix release, without anything complex like using Docker/ECS/Kubernetes/etc. To simplify the usage of FLAME with simple Mix releases, FlameEC2 brings the FLAME library to EC2 nodes, allowing you to bypass setting up any infrastructure outside of your normal release process.

The FLIP technique is a way of animating an element on a page so that it seamlessly transitions between different positions and sizes.

This library brings flip_wrap, a component for LiveView that allows wrapping any element in an automatic FLIP animation for you automatically.
