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.

👋🏼 Here’s part eight of the Building a simple Calendly clone with Phoenix LiveView series, in which we’ll finish managing event types adding the corresponding logic for cloning and deleting event types.

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.

• 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! 😄

Learn how to deploy your Elixir Phoenix app to Fly with a single command then set up Continuous Deployment using GitHub Actions. This post has been updated using Chapter 1 and 2 of the Phoenix Deployment Handbook.

https://romankotov.com/articles/elixir-module-registry-via-protocols.html This post describes how to use introspection feature of protocols to create a compile-time module registry.

This approach helps me to tag modules and gather some useful information about them. Using it in my Elixir Smart Home project

It also covers another ways to create a module registry, and some pitfalls that I have faced to make it work.
