What does the :default option actually do when you set it on a field in the Ecto schema? This blog post makes a dive into this, to understand how this option works, and discuss when to use it.

Runtime Exceptions are the bane of my existence.

How do we maintain compiler benefits while using behaviors?

With a little bit of compile-time config, that’s how.

In this episode, we’ll build on what we did in part 1 and create a form that filters our albums using Flop.

A blog post with a brief introduction to daisyUI and its features, and how you can integrate it into your Phoenix project with just a few lines of code!

A blog post on using :noreply and GenServer.reply to allow a GenServer to continue working even while its callers wait for the result of long-running operations.

I love using LiveBook to prepare my blog posts! It’s great to have the code, prose, and visualizations all in one place. While working on this one, I used a simple filesystem cache to avoid unnecessary re-evaluation in cells that were expensive in terms of time and OpenAI credits… I’ll have to share that tip in a future post.

New video from Bruce Tate in the updated OTP course. Tasks are short-lived GenServers our code can spin up to handle intermediate jobs concurrently. These genservers don’t hold state indefinitely or process loops. Instead, they do a concurrent job and return a result. https://youtu.be/O0JxVTqVV9w

This is a fantastic article written by our Launch Scout team member and Principal Engineer, Andrew Ek about supporting and building the Elixir community. https://launchscout.com/blog/supporting-elixir-or-other-communities

In part one of this series, we introduced the core generated components when bootstrapping a new Phoenix project. We used a button and a modal from the core components to lay the groundwork for a “create modal”.

In this post, we will put a form onto the modal and create pets.

LiveView 0.19 added phx-viewport-top and phx-viewport-bottom to help with infinite scroll

Just tested it and was amazed that a one line change allowed me to remove my entire InfiniteScroll JS hook! 🤯

Episode 162 of Thinking Elixir. WebAssembly is an interesting technology that feels completely separate from Elixir. Patrick Smith created an Elixir project called Orb, an Elixir DSL for WebAssembly. He also shows how a WebAssembly component can play a meaningful role in a LiveView page! We talk more about what WebAssembly is, the promise for the technology, how it can improve UX, and where Patrick sees real practical applications for Elixir developers.

I’ve had a number of conversations with folks who want to help the Elixir community, but who don’t know where to start or feel intimidated by “just make an open source library”. This article provides several concrete things people might try, ranging in size/difficulty from “I can spend 10-15 minutes per week reading and sharing what I learn” to “I can hire Elixir developers!”

I imagine many think ExUnit just does some scripting to run tests.

But it’s actually a full Elixir app! I think that’s awesome 😎

A lot’s changed since Chris McCord’s fantastic LiveView twitter clone video!

I wanted to showcase what’s happened in LiveView since then, including:

• Live file upload
• Streams
• phx.gen.auth improvements
• LiveView Core Components
