The Primitives of Elixir Concurrency: a Full Example

Previous articles about Concurrency in Elixir:\

Let’s put in practice what we’ve seen in the last few articles about concurrency. In this article we see how to fully make our initial cryptocurrency example, using just HTTPoison module and spawn, send and receive to handle concurrency. At the end we will refactor it using Task, which makes everything far easier!

Hey Process, there is a Message for you!

We already saw how to spawn new processes to run our code concurrently, doing multiple HTTP requests at the same time, getting cryptocurrency prices.

Without messages and coordination between processes, the only way to see the results was to let each process printing each price once finished.

Spawning processes in Elixir, a gentle introduction to concurrency

Along with pattern matching, one of the coolest things in Erlang and Elixir is their concurrency implementation based on Actor model. In this article I introduce concurrency and show how we can start making our code concurrent in Elixir, using processes.

Concurrency

We can think of concurrency as dealing with multiple things happening, and progressing, at the same time.

The Beauty of Pattern Matching in Elixir

Transcript

One of the reasons I fell in love with Elixir is pattern matching and how it can be extensively used all over the code.

Match Operator

Let’s start the interactive Elixir console, iex and let’s do what is seems to be a normal assignment

Running Elixir in Docker Containers

Wed, 12 Dec 2018 14:15:00 +0000

One of the wonderful things about Docker Containers is that you can easily freeze your environment and application in a Docker Image, and deploy it in production without worrying about installing dependencies on your servers. It just works. This is also great for debugging. If something doesn’t work in production, you can run exactly the same image locally in matter of seconds. The features and advantages of docker obviously don’t stop here. In this article we see how to use Docker to run our development Elixir environment and to run multiple Elixir Nodes over a Docker bridge network.
