Elixir 1.12 introduced two very useful macros. They can be life savings helpers in your codebase. Instead of write extra functions, you can have nice logging and executing actions based on given data.

Since Phoenix LiveView 0.16 has brought new HEEx templates (and LEEx are going to be deprecated), you may come across issues during migration.

In episode 86 of Thinking Elixir, we talk with Derrick Reimer about his product SavvyCal. He used Elixir as a solo dev to create a service that can take on an 800lb gorilla like Calendly. He shares what competitive advantages he feels he has both from Elixir but also in being more nimble. We also talk about creating a company as an independent, solo developer and how that can work. Derrick shares some tips and resources that were helpful for him on his journey. We feel the PETAL stack positions Elixir developers well for optionally taking that Indie path if desired. Check it out! Lots of nuggets here!

I love LiveView. Navigating between views is so fast! This quick tip makes navigating feel instantaneous by adding a split-second delay before showing the progress bar. Such simple change makes a big difference!

In this video I try to explain some of the fundamentals of moving from other programming languages and into Elixir. Going functional was a bit challenging for me and I hope this helps some of y’all.

Happy coding!

The handle_params/3 callback is helpful for using the state in the URL to drive the presentation of your LiveView. his is nice because you can share the URL with anyone and see the same LiveView state. https://til.simplebet.io/posts/jhhvhiyczv-when-to-use-the-handleparams-callback

Defines module attribute getter automatically.

AttrReader

In Elixir, Module variable is often used as a constant. But I didn’t want to bother to define a getter when I wanted to refer to it with Test code etc. If you use AttrReader, you can use it without having to define the getter of the module attribute.

Links

• github: https://github.com/tashirosota/attr_reader
• hexdoc: https://hexdocs.pm/attr_reader/readme.html

Usage

Defines by use

iex> defmodule UseAttrReader do
...>   @foo "foo"
...>   use AttrReader
...>   @bar :bar
...> end

iex> UseAttrReader.foo()
"foo"

iex> UseAttrReader.bar()
:bar

Defines by macro

iex> defmodule UseAttrReaderMacro do
...>   require AttrReader
...>   AttrReader.define @foo
...>   AttrReader.define @bar, "bar"
...>   AttrReader.define @baz, :baz
...> end

iex> UseAttrReader.foo()
nil

iex> UseAttrReader.bar()
"bar"

iex> UseAttrReader.baz()
:baz

In episode 85 of Thinking Elixir, we talk with Cocoa Xu about his PhD robotics project and his related Evision project that creates Elixir bindings to the OpenCV library. The project enables computer vision in Elixir much easier by building on existing projects. We learn about the kinds of features this enables and how it can target embedded devices as well. His goal of a clustered, collaborative, hoard of Elixir robots is terrifyingly fascinating! 😄
