Although Elixir is a relatively new programming language, it is gaining popularity thanks to its concurrency, scalability and high fault tolerance.

Many market leaders recognized that potential and are choosing it for their new projects or replacing previous technologies with Elixir.

This video tutorial covers setting up Chrome Webdriver, configuring Wallaby to use it and it digs into some of Wallaby’s testing features:

• Scoping down find queries
• Walkthrough of Wallaby.Query source
• Building re-usable queries
• Putting a query into a module attribute

I started to work on this library about a year ago, it was put in production around December 2018. I figured it is time to publish it as a package.

Streams are neat when you are dealing with potentially infinite data sources. For instance, you query a database table and process returned rows as they arrive. Unfortunately, should a network hiccup happen, the entire stream would fail. Naively retrying the query could be expensive. RecoverableStream moves stream evaluation into a separate process, to isolate errors.

Wallaby is a library for running end-to-end integration tests in Elixir (probably Phoenix) apps. This screencast tutorial starts from a freshly installed Phoenix (v 1.4.9) app called “Wally”, installs the needed libraries, configures the app to use them and writes an integration test.

Take a deep-dive into Broadway as we build a simple data pipeline, and then improve its efficiency by using batchers.

Batching for Operations with Elixir and Broadway

In Elixir we deal with dependencies on a daily basis. For many developers, it’s not very clear what the difference is between the instructions we use for this task. Read Szymon’s article to learn more about this topic.

Submit your proposal and come enjoy a weekend with the BEAM community, the free software community and lots of good beers in Brussels!

I had reason to dive into dynamic repos for a project. Multi-tenancy was trickier than I thought it would be but is also very much doable with the APIs Ecto provides for it. This post covers the basics with more to come.
