A new blog post by Daniel Caixinha about testing in Elixir. This is part 1. More to come soon! https://medium.com/onfido-tech/the-not-so-magic-tricks-of-testing-in-elixir-1-2-89bfcf252321

I found myself wanting documented state of my database within my Elixir/Phoenix app, similar to what schema.rb or schema.sql provides in a Rails app.

Announcing the initial release of PostgresDescribe. Does what you think it does - generates a set of files on disk that contain the output of the \d command in a PG shell.

Building the Alchemist.Camp website, Part 5.

Today, we added ability to dynamically render and serve up EEx template files, without requiring a restart of the web server. In the process of building this, it was convenient to flesh out our minimal clone of Plug.Conn a little bit.

Building the Alchemist.Camp website, Part 4.

In order to properly set response headers, we begin writing a minimal clone of Plug.Conn. Soon it will be possible to write templates, views and controllers for our site

Performance improvements

• More WHITE_SPACE/less EOLs, so less reparsing when adding/removing spaces or line
• Credo annotator can be configured to trade-off less details for less CPU usage

In this introduction to pattern matching we walk through a few examples of how it’s used in Elixir.

Sage is an dependency-free implementation of Sagas pattern in pure Elixir. It is go to way when you dealing with distributed transactions, especially with an error recovery/cleanup. Sage guarantees that either all the transactions in a saga are successfully completed or compensating transactions are run to amend a partial execution.

It’s like Ecto.Multi but across business logic and third-party APIs.

Step one of crawling a web page is getting a fully fleshed out URL pointing to that page. The problem is that people usually think of URLs in fuzzy, incomplete terms. Thankfully, fleshing out the missing details is simple with Elixir.

I used to think that because length/1 was slow in guard clauses and could easily be replaced by pattern matching, that all guard clauses should be replaced by pattern matching. Turns out, some of those guard clauses are really quite quick!

Posted a new proposal to the mailing list, please take the time to read over it and let me know your thoughts! As new features can only be added if they’re supported on the mailing list, it’s vital that thoughts make it there :)

For those interested in deploying an Elixir/Phoenix app to Google Cloud, I’ve posted three getting-started tutorials on Google’s community site:

• Deploying to App Engine for spinning up an app with a minimum of work
• Deploying to Kubernetes Engine to get on board with containers
• Deploying to Compute Engine if you want complete control over your cloud resources

I love that mix hex.docs open ecto opens Ecto’s docs in my Browser. I’d love to have something like mix hex.readme open plug to open README.md files just as easy.

Given the current rage in team registrations (we have 28 already 😱), we decided to extend the registration deadline for @spawnfest one more day! #erlang, #elixir, #lfe devs… you have until tomorrow to register your team at https://spawnfest.github.io/registration and win some awesome prizes!
