I had a load of fun figuring out everything for making this video on @ElectricSQL. Syncing between SQLite and Postgres. Local first. Active-Active replication.

If you like SQLite AND/OR Postgres. This should be for you. https://www.youtube.com/watch?v=_U5Z8AQy0hc

Phoenix LiveView 0.18 added new features to manipulate focus and improve accessibility in your Phoenix LiveView apps. In this post, I show you all of these features, and provide real-life examples to demonstrate just how simple it is to use them and enhance your app’s accessibility. https://fly.io/phoenix-files/liveview-accessible-focus/

Did you miss the webinar on exploiting serialization in Elixir? Don’t worry, the recording is up on the Paraxial.io YouTube channel.

In this tutorial, we’re going to build a simple Phoenix application based upon NimblePublisher. I will then show you how you can integrate Haystack to add full-text search for your content.

Building a LiveView powered chat app is easier than ever when using Streams! Sophie DeBenedetto shows us how in this article. She createa a Slack-like chat client with infinite scroll back, editing message, deleting messages, and appending new message to the bottom. It’s slick and efficient, not storing any of that data in the LiveView.

While we wait for things to get sorted I’ve set up a new discord server for Elixir enthusiasts to gather. Join here! https://discord.gg/HH8Dqbs3

There are 2 ways to test Phoenix function components:

• render_component/3
• rendered_to_string/1 + ~H sigil

Use the second one every time!

So much nicer ergonomics ✨and allows us to test more complex components (e.g. with slots). 🎉

This blog post is an overview of how Haystack is built, the motivations for the project, and the design decisions I have made to allow Haystack to be as simple and extendable as possible.

In this episode, we’ll utilize dynamic function calls to build a web-based application that helps people learn Elixir.

Episode 143 of Thinking Elixir. New minor LiveView release, a new Nerves focused Elixir case study was published, a post about audio transcriptions using Bumblebee and another about using Tailscale to cluster Elixir apps across cloud providers. ElixirConf US was announced, nimble_options reaches 1.0 and more!

In part two of this three-part series on testing data with Elixir, we’ll look at using data generation functions: https://blog.appsignal.com/2023/03/21/generating-data-functions-in-your-elixir-app.html

A brief walk-through of functional arrays in Elixir and Erlang: https://readreplica.io/functional-arrays-in-elixir-erlang/

“Programming Machine Learning” guides you through the creation of an image recognition application from scratch with supervised learning, iteratively and step-by-step.

All the code examples provided with the book are in Python/numpy, but I wanted to give Elixir a spin using Livebook, Nx and Axon, therefore I started to rewrite all the Jupyter notebooks in Elixir.

All the livebooks can be found in this Github repository https://github.com/nickgnd/programming-machine-learning-livebooks

In Chris McCord‘s 2nd Phoenix Dev Blog post, he delves into diagnosing and fixing an 8-year old LiveView race condition when long-polling. Even if the bug didn’t affect you personally, his deep dive illuminates how things work as he walks us through the diagnosis and multiple levels of the problem and the final changes. A great guided-tour with insights shared along the way!

Have you ever found it difficult to work with maps that sometimes have string keys (if it’s controller params coming from outside) and sometimes atom keys (if it’s params defined inside of the code)?

If so, consider using our newly published map_with_indifferent_access library, which gives you functions such as MapWithIndifferentAccess.get/3, MapWithIndifferentAccess.put/3, that mimic the Map.* functions.

The advantage of using them is that you don’t have to worry if the map currently uses string or atom keys. You, as the caller, only use atom keys. The underlying code will automatically deduce if the map uses string or atom keys, and depending on it, convert the key to string or leave it as atom, before handing it further to the original Map.* function.

This will prevent you from reaching a Ecto.CastError saying it received a map with mixed key types.

(Inspired by Ruby on Rails’ HashWithIndifferentAccess.)

At Welcome to the Jungle, we have been using Elixir in production for five years now, and in this article we are going to share our feedback on how things have worked out. https://medium.com/wttj-tech/the-benefits-of-using-elixir-for-backend-development-our-perspective-9d421fde426a
