WombatOAM: Everything you need to know about your Elixir system.
The resource/3 and the closely related iterate/2 and unfold/2 functions in the Stream module were completely unknown to me and seemed worthy of some deeper study. After spending time researching and banging out a few examples, I realized that these functions are extremely useful and underrated tools for generating complex enumerable sequences in Elixir.
The Elixir language is dynamically typed with lots of helpful documentation. It builds on Erlang and the Erlang VM. You can be up and running almost immediately. If your app compiles, it's already deployable. The Phoenix framework for Elixir apps is genuinely exciting to use. Let's build an easy-to-use application that manages upcoming events, built with the Phoenix Framework and authenticated with Auth0.
In the previous articles, we have implemented the Toy Robot (you can find it here Part 1 and Part 2). This time we will improve the implementation and turn it into a console application. In that application, we will be able to run the simulator and give commands to the robot.
Elixir is a functional language… and Phoenix takes it seriously. The web seems to be a perfect fit for functional languages. You invoke a function passing some arguments and you expect a result, or speaking in web related terms, you make a request to an URL with some parameters and you expect a response.
During the last year I liked functional programming, the Elixir language, the community, parallel tests, the fast workflow, the dependency management and the powerful platform. I had troubles with Erlangs cryptic error messages, IDE support, code density and deployments. My excitement for Elixir is still as high!
