Authex - a simple JWT alternative.

Many of our app API’s use the same process for JWT authentication and authorization. I finally had time to extract things into releasable libraries. A simple alternative to some of the other options available out there. Includes authentication, authorization, as well as blacklisting.

Hope someone can find it useful.

Grokking the Y Combinator with Elixir

Trying to understand the Y combinator has always left me with a throbbing headache and a craving for pretzels. But recently, while reading through The Little Schemer, I had a moment of clarity which left me with a much deeper understanding of how the whole thing works.

Check out Grokking the Y Combinator with Elixir for a step by step breakdown of what the Y combinator is, why it’s interesting, and how it can be derived through plain old Elixir code.

Announcing Bootleg: Simple deployment and server automation for Elixir.

Many in the community are already aware of Bootleg, but I just published a quick “official” announcement over on the Lab Zero blog with a very quick guide to getting started.

Drab 0.6.1 is out, with better living assigns and shared commanders

Drab is an extension to Phoenix, designed to remote (from the server side) control the user interface.

The library has completely redesigned custom EEx engine, so it is not putting its <span> in every corner of your template anymore.

Also, this version introduces shared commander, allowing you to create components of Drab’s template + commander.

Check out the demo page, install, test, develop and enjoy!

New book: Phoenix for Rails developers

You invested thousands of hours learning Rails and how to master its features to build web applications. This book will help you to learn Phoenix, using the knowledge you already have.

Elixir on Docker

Quickly get started developing clustered Elixir applications for cloud environments. - Looking for Elixir/Phoenix developers (open source)

The project

CaptainFact is a collaborative, real-time fact checking platform. Its goal is to help us improve the way we consume medias on the Internet by collectively sourcing and debating about the content we see.

Think Wikipedia (sourcing) + StackOverflow (reputation, achievements) applied to our day-to-day information.

The project currently offers two linked tools:

  1. A real-time debate platform that allows us to have rich and focused discussions on a video by working point by point, argument by argument - instead of taking the content as a whole like almost all today’s comment systems do:

  2. A browser extension that is bringing this information directly on the content you’re watching:

In the future we’d like to extends these functionalities to be able to work on news articles (text) as well. For more details about the reasons of the project, its philosophy and its goals, you can check this article.


Though frontend’s and extension’s code are already available on our Github, we’d like to have some volunteer Elixir / Phoenix developers checking the API code before we release it.

There will also be a lot of other stuff to work on in a near future, like:

  • Migrating some parts of our -or maybe the entire- API to GraphQL
  • Implementing a notification system
  • Password-less authentication

You can contact us on Facebook or by email ([email protected]) if you’re interested in participating!

What's wrong with a global User module?

We often see a User module in the root project directory. Here are some thoughts about its impact on the system architecture and some examples how to split it into cleaner and more isolated components.

Might be helpful to understand how to separate the code when using Phoenix Contexts.

Just in time for Spooktober: `Ghoul` 0.1.1: An undead cleanup crew for your processes

Ghoul.summon/2 raises one of the undead to stalk your process, waiting until just after death to consume the corpse… err… execute a custom callback.

Ghoul.reap_in/3 invites the carrion eaters to slay a misbehaving process after a timeout, unless reap_in is called again to set a new timeout, or cancel_reap or banish prevent the Ghoul from mincing up his tasty treat.

I’ve been using this in production for a few months, and it has elegantly solved some tricky issues; my current favorite is delaying a supervisor’s restart of a worker, but only when the worker exited while in a particular situation.
