José Valim posted this message on Twitter. So here is my experience integrating phx_gen_auth with OAuth for a Phoenix LiveView app. Some Background I’m working on (yet another) personal project. It’s a multiplayer browser game written in elixir/phoenix/live_view/surface. If you did not try surface yet, please do. It’s awesome! But more…

Phoenix contexts are a great way to organize the code. They separate the business logic from the web related logic. They group together schemas and business logic. And provide clear ways of inter-contextual communication. If you are new to Phoenix, I recommend reading at least the official contexts docs before…

Updating the Phoenix LiveViews from outside the process — LiveView is the new cool thing in the Phoenix world. I will not try to say what it does and how it works. There are already many articles and tutorials doing it. I will skip also the installation part, which is covered by the docs. So let’s start directly with…

The challenges of building a small distributed Elixir Application — When building a small application is quite easy to overlook the (horizontal ) scalability related aspects. Especially in the early phases. You want it ready and deployed in production. You can build on top of it later on. And I don't say it’s a bad approach. But at least keeping…

A while ago I read this article about Sagas Pattern and its Elixir implementation: Sage. It immediately got my attention, as a nice way of error handling. I’ve explored error management (from a different perspective) in the Functor Flavoured Pipes in Elixir article. …

As you may guess, this article is not about rebuilding the Elixir GenServer. It’s already there and it works great. And that’s what interests me the most: why it works great? Also, we will not discuss what GenServer does and its generic concepts. If you are not familiar at all…

(Even More) Functional Elixir — 2 In the last article, we explored some functional concepts such as currying and composition. And how to apply them to Elixir. Reading through the same book, Professor Frisby’s Mostly Adequate Guide to Functional Programming, another concept draw my attention: functors. According to the same…

(Even More) Functional Elixir — 1 — If you (like me) got into Elixir from an object-oriented language, then concepts like currying, function composing and pointfree functions may not be very familiar. Some of them do not apply by default to Elixir. But they are part of the general functional programming (FP) concepts and worth exploring. I…

GenStage Under Umbrella — Part 4 — GenStage Under Umbrella? GenStage Under Umbrella — Part 1 Testing The GenStages Under Umbrella GenStage Under Umbrella — Part 2 Implementing GenStages Under Umbrella GenStage Under Umbrella — Part 3 This is the last article in the GenStage under Umbrella series, and the shortest. We made quite some progress. We have a working application and tests are passing. GenStages are sending and receiving the expected information across the Umbrella apps.
