While refactoring a phoenix application, lazy me figured typing the full path to a test was terribly annoying. So here’s mix_phxtest, a helper package to allow running specific tests with shorter commands.

We’ve recently gone through a round of pen testing and had to deal with feedback on our use of WebSockets. Here is what we’ve done to get the WebSocket code to pass those pen tests

I have been asked multiple times recently questions about Elixir and if it’s a good fit for different projects. Let’s try clearing a few things out

In episode #46 we’ll look at how we can use virtual attributes in Ecto to create fields in a schema that we don’t want persisted to the database.

Just published Odometex v0.1.0, simple distance comparisons for Elixir! 🌍🚶‍♂️🏃‍♀️

iex> Odometex.compare(7000)
# => [
  %Odometex.Result{label: "Central Park, New York", meters: 4000, times: 1.75},
  %Odometex.Result{
    label: "Champs-Élysées, Paris",
    meters: 1910,
    times: 3.664921
  },

Juice can collect and reject string or atom keys from an Elixir Map or List.

Given the map

iex> fruit_basket = %{
    apples: {
        granny_smith: 10,
        golden_delicious: 3
    },
    "oranges" => 5,
    plums: 6,
    "mangos" => 2,
    recipients: [:steph, "michael", :lebron, "charles"]
}

Return everything with a wildcard *

iex> Juice.squeeze(fruit_basket, "*") == %{
    apples: {
        granny_smith: 10,
        golden_delicious: 3
    },
    "oranges" => 5,
    plums: 6,
    "mangos" => 2,
    recipients: [:steph, "michael", :lebron, "charles"]
}

Remove plums and mangos

iex> Juice.squeeze(fruit_basket, "* -plums -mangos") == %{
    apples: {
        granny_smith: 10,
        golden_delicious: 3
    },
    "oranges" => 5,
    recipients: [:steph, "michael", :lebron, "charles"]
}

Only collect granny_smith apples and oranges with nested . notation

iex> Juice.squeeze(fruit_basket, "apples.granny_smith oranges") == %{
    apples: {
        granny_smith: 10,
    },
    "oranges" => 5
}

Collect plums and mangos for charles

iex> Juice.squeeze(fruit_basket, "plums mangos recipients.charles") == %{
    plums: 6,
    "mangos" => 2,
    recipients: ["charles"]
}

Brotli is a relatively new compression format that has two big advantages over gzip. It’s faster at compressing things and it compresses them down to nearly ~25% smaller files!

Let’s set up our Nginx server to serve brotli compressed HTML, CSS, JS and JSON assets! If you’re running Phoenix, Rails, Django, Node or anything else behind an Nginx proxy, this setup should work for you.

A basic strategy is also covered for serving brotli compressed assets from a Phoenix server running directly on the server without anything proxying in front of it.

Protocols are one of the more important but less publicized features of Elixir.

That’s why this lesson focuses on them directly rather than being part of a larger project. It explores defprotocol, fallback_to_any, defdelegate and working with structs.

While building and testing a decoder to go along with the Bitcoin BIP-39 encoder we wrote a few weeks back, a simple property test uncovered a bug in our original implementation that I never would have caught through manual testing.

I’m blown away.

Check out the full article for a rundown on my property testing experience, and the full implementation of the decoder: Reversing BIP-39 and the Power of Property Testing.
