After reading this post by José Valim, introducing their new company Dashbit and the blog they built, I felt an urge to share the story of Real World Phoenix. So here it is…

Find out how to handle migrations that involve systems other than the database itself, while keeping the entire process idempotent and backward-compatible.

Elixir is a strong dynamic language in the Type System Quadrant. What does that mean? My blog post explains it!

In addition to OO vs FP, understanding where in the quadrant the language you are coming from is helpful as you learn Elixir.

Fairly large update to handle forms with hidden fields. This update treats forms as parsed trees, has more informative output, and is generally more flexible. This entire update is brought to you by the hard work of Brian Marick (@marick on GitHub). Thank you!

I stumbled upon the reimplementation of the very limited wc unix utility functionality in Haskell by Chris Penner, and have it redone in pure Elixir.

In this post I cover the whole “optimization” process, starting from naïve implementation and walking down the road with generated pattern-matching clauses and using Flow to make it concurrent with two lines of code.

Spoiler: I was able to beat C and be even with the aforementioned Haskell solution.

It’s really dumb and naive, not at all optimized but still >18x faster than the library I was using.

This version of Morphix (0.8.0) is compatible with Elixir 1.10. We had our own is_struct method implemented which will now be replaced with Kernel.is_struct. Morphix is a tiny library of helper methods for transforming and partitioning Enumerables.

In this episode of ElixirMix, we visit with Steven Nunez about how Flatiron School adopted Elixir and is using RabbitMQ. He shares how he decides to “rails new” or “mix phx.new” for a project. How adopting Elixir in a team goes better when the team “falls in love” with what it gives them. Steven shares how their RabbitMQ queues are setup, how the messages are designed, how to spread the patterns throughout the teams and projects, and much more!

Just released a Phoenix adapter for Inertiajs (The Modern Monolith):

https://github.com/devato/inertia_phoenix

Inertia.js lets you quickly build modern single-page React, Vue and Svelte apps using classic server-side routing and controllers.

inner_cotton is a set of static analysis of Elixir codes, and a set of mix tasks to help initializing and maintaining OSS/production codes.

https://hex.pm/packages/inner_cotton/0.6.0

Changes in v0.6.0 are :

• Support Elixir 1.10
• Drop Support Elixir 1.8 (It may work but not supported.)
• rrrene/inch_ex returns
• Moves Travis CI from mix cotton.init to mix cotton.init.travisci
• Supports GitHub Action in mix cotton.init.github
• Supports GitLab CI in mix cotton.init.gitlab
• Remove fast_yaml dependency
• Update deps

Article about pitfalls when handling partial unique indexes and upserts with Ecto. And dog politics.

https://medium.com/@woylie/adventures-in-ecto-and-postgresql-partial-unique-indexes-and-upserts-with-associations-ccf20114dfa1

http://johnwilger.com/2020/02/16/ecto-custom-unique-constraint-trigger.html

I recently needed to enforce a database constraint similar in spirit to a unique index, however the criteria for what should be considered “unique” was more complex than what a simple unique index in PostgreSQL would be able to deal with. Knowing that Ecto’s unique constraint validation works by intercepting an error raised by the database, I set out to see if I could implement the complex unique constraint logic in the database and still be able to use the Ecto.Changeset.unique_constraint/3 validation without needing to modify any Elixir code.

Part 4 of the Simple Phoenix LiveView App series. This episode covers three things:

• Pass connection info to our socket in endpoint.ex
• Set up CSRF tokens for use with LiveView via sockets
• Convert the embedded ~L template in our LiveView render function to a separate .leex file

Have just merged in a great PR by @marick into phoenix_integration, which much improves form testing. Am going to leave it in master for a week before pushing to hex, so let me/us know if there is any feedback. This bumps the version to 0.8.0

Once an Elixir project is large enough, maintaining config files and config variables becomes a nightmare.
