In distributed systems there is usually a need for the asynchronous transmission of messages to one or more services or processes. If you have used Phoenix you might have discovered that it provides a flexible way of solving this problem through a built-in pubsub framework called Phoenix PubSub. Currently, it officially supports pubsub based on PG2 and Redis. It uses so called adapters to provide a pluggable interface for different pubsub implementations.
Phoenix LiveView has been a dream to work with so far. I really recommend looking at it for your next web application. Building Tailwind, Elixir, and Phoenix LiveView with some Vue sprinklings has been the most enjoyable tech stack I’ve used in a long while.
In today’s post, we’ll learn about Mnesia, see when you would use such a tool, and take a look at some of the pros and cons of using it. After covering the fundamentals of Mnesia, we’ll dive right into a sample application where we’ll build an Elixir application that uses Mnesia as its database. Let’s jump right in!
Configuration has long been a hot topic in the Elixir community, and luckily, in the recent months, there has been a great deal of thoughtful work put into making this problem an easier one to solve. Today, we’re going to show you how to migrate from an Elixir application that has been configured with the widely used config/*.exs files at compile-time, to an application that instead uses environment variables for configuration and is configured at runtime.
The article has two parts. In the first one, I list resources for completely new Elixir developers. Once you finish up with these, the second part is a collection of further suggestions to help you improve your skills.
