Ember Best Practices

Some thoughts and ideas on best practices building Ember apps after 2 years building and maintaining 6+ apps. This is less about the obvious best practices, like use ember-cli, and more along the lines of when to use what technique. As with every best practice there are exceptions to every rule.

Routing

alanpeabody

# Reload/recompile code before each request in development only using Plug & Mix.
# Assumes MyApp.Router is a plug that handles actual routing.
def MyApp.Main do
  use Plug.Builder
  
  plug :reload
  plug :dispatch
  
  def reload(conn, _opts) do
    if Mix.env == :dev, do: Mix.Tasks.Compile.Elixir.run(["--ignore-module-conflict"])

Goal

To pull in dependencies and have them run their migrations in the parent apps' repo.

Setup

MyChild - A mix application with ecto migrations, schemas, etc. MyParent - A phoenix application that wants to leverage the child application.

In this case MyParent has added MyChild as a mix dependency via github, eg:

  # API

  def start_link do
    GenServer.start_link(__MODULE__, %{}, name: __MODULE__)
  end

  def set_item(key, val) do
