Disco: simple, opinionated yet flexible library to build CQRS/ES driven systems.

Simple, opinionated yet flexible library to build CQRS/ES driven systems.

Disco has been extracted from work done to build apps following the CQRS/ES pattern. Several ideas come from other excellent examples such as commanded. However, the goal was to build something simpler and more flexible, because it’s not always possible to follow 100% CQRS/ES pattern neither anywhere in your apps. Disco tries to solve this gap.

Sigils To The Rescue

As I continue working on Exvalibur, the generator for blazingly fast validators of maps based on sets of predefined rules, I have implemented custom guards and pattern matching of values.

I just blogged about how I used custom sigils to allow quoted expressions in the rules.

Breaking the rules when writing unit tests

This is part 3 in a series on unit testing in Elixir. In this post, I show two of the places where I break some of the rules that I set out earlier when I’m writing unit tests: http://devonestes.herokuapp.com/unit-tests-in-elixir-part-3

nerves_neopixel is now Blinkchain!

If you want a fun project to hack on over the upcoming holiday, pick up some NeoPixel RGB(W) LEDs for your Raspberry Pi-based Elixir/Nerves device and check out the latest release of blinkchain (formerly known as nerves_neopixel). It now supports commands to draw on a mutable 2D virtual canvas (e.g. composed of a bunch of strands or one or more Pimoroni Unicorn hats) instead of having to calculate the updated values for all LEDs manually each “frame.”

Check out the example and let me know what you think!

Morphix 0.5.0 released, now with unordered equality!

We sometimes run into a problem where we want to compare two enumerables for content, irrespective of ordering. So we’ve added equalify and equaliform (recursive version) methods to morphix to handle that situation. https://hex.pm/packages/morphix

Map vs List Performance

An optimization I made to use a map instead of enumerating through lists to match elements of a big dataset took the operation time from 30+ minutes to less than a second.
