Instachat

The Phoenix Framework was built with realtime communication as a first class priority. Using its built in socket handling and channels we can implement a basic, realtime chat application with little effort.

For this video we’re going to assume that you already have Elixir and Phoenix Setup. You will not need a database as the messages will not be persisted. This tutorial is taken pretty much directly from the Phoenix Documentation.

Setting up the app

To start let’s generate a standard phoenix application:

$> mix phoenix.new instachat

Prototypal Inheritance

Goals

By the end of this lesson students should be able to:

Demonstrate a use case that explains prototypal inheritance
Demonstrate what kind of flexibility prototypal inheritance gives programmers

Summary

In this lesson we are going to learn about a type of inheritance called Prototypal Inheritance. We are going to see how with prototypes we can share functionality between related objects. We are going to see how with Object.create we can easily set up prototypes and how we can extend prototypes to easily add functionality.

Elixir Debugging Techniques

IO

Old standby for a quick look into your code

IO.puts

Works with anything that implements the String.Chars protocol, AKA the to_string method. Elixir ships with: https://github.com/elixir-lang/elixir/blob/e769afbed96b6b9eee6a4f4ac4a6ea00bc0630f7/lib/elixir/lib/string/chars.ex

IO.inspect

Returns the term handed to it untouched so you can plop it straight in your code
