Credo, a new static code analysis tool that acts as a code linter, but also focusses on teaching coding practices and code consistency.

Trans has been updated to 2.2.0

Trans, the small library for embedded translations in Elixir schemas has been updated to 2.2.0.

The main change in this new version is that Trans.Translator.translate/3 can now receive a string, allowing us to use the output of Gettext.get_locale/0. For example, we can now write:

Trans.Translator.translate(Article, :title, Gettext.get_locale())

This release also removes Faker as a dependency, updates ExDoc and removes support for Elixir versions older than 1.6 (which are not officially supported by the core team anymore).

You can see the release notes on GitHub or fetch the new version from

Expecting the Unexpected in Elixir

A recent project created for the Stockholm Elixir meetup group. I used Elixir and Scenic to create a fault-tolerant spaceship dashboard for Kerbal Space Program (with a brief NASA history lesson)

Simple Phoenix LiveView App: Planning DB Schemas

This is a continuation of the Simple Phoenix LiveView App series that started with basic setup and a minimal interactive app that captured keyboard events last time.

This time we’ll plan out schemas, look at the relatively complex associations used in a large content site like Alchemist Camp, as explained in the earlier series, and then decide on a good schema structure for this newer, simpler app.

A proposal for an Absinthe application structure

One of the great things about GraphQL is how broad the abstractions are. Everything is just an “object”, with “fields”! This makes things infinitely composable, and is where a good deal of the power in GraphQL comes from. But, like all things, there are downsides to this - first and foremost (in my opinion) is that it makes organizing a project difficult. Because you can do just about anything, you might end up doing that, and having a fairly difficult time of finding things and knowing where to put stuff. But, most importantly, this can make talking about GraphQL applications difficult since some of these terms are really murky.

Credo v1.2.0 released

I released v1.2.0 of Credo, the static code analysis tool emphasizing code consistency and teaching.

Lumen - Elixir in the Browser

My thoughts on Lumen and a guide to trying the current bleeding-edge development version yourself. Where you can write Erlang or Elixir to run in your browser. Thanks to the Lumen team for the help on all of this.

A layered object store design in Elixir (Part V) - The Web layer

This is the final layer for our object store responsible for exposing it over the web. It exposes endpoints: /upload for uploading a file and /file/:file_id for getting a file by ID.

We used simple and elegant plug abstraction for providing an HTTP interface with routing, avoiding use of any web frameworks: though Phoenix is quite modular, it may not be needed for thin Web layers (as they should be).

Cool Elixir libraries

All Ruby/Rails developers know that for features neither provides, there is probably a Ruby Gem contributed by someone in the community that solves that problem.

Elixir’s equivalent to Ruby Gems are Hex packages. Hex is a package manager that provides reusable libraries for both Elixir and the Erlang ecosystem…
