This series will take us through building and structuring an application with an Ember front-end built with ember-cli and a Ruby on Rails backend. We’ll discuss project structure, testing, and deployment to Heroku.
During the course of this series I am going to re-build the Boston Ember website. (if it looks terrible that means I’m not done yet)
Getting setup with our tools
Let’s start by making sure all relevant dev tools are installed on our machine. I am using the following:
- Ruby 2.1.1
- Rails 4.2.0
- Node 0.12.0
- npm 2.7.0
- Postgres (only necessary because we are deploying to Heroku)
Versions at or above these versions should be OK for following along. Please refer elsewhere on how to install these tools on your development machine.
Next I will install ember-cli
npm install -g ember-cli
Confirm that you have
You should see:
Or a greater version.
Setting up our project
For this project we will keep our Rails and our Ember apps in separate directories with a top-level directory containing the two. We’ll have to do some project generating and renaming.
I first create a new top-level directory:
Now we’re going to generate our Rails project:
rails new bostonember -B -S -d postgresql
mv bostonember rails
Note how we renamed the directory the Rails project is in to
does not affect anything in that directory. If you do not have Postgres
on your machine omit
Now the ember project:
ember new bostonember --skip-git
mv bostonember ember
Now it should be obvious why we moved the Rails project. We should now have a structure like:
Let’s confirm that our ember app runs:
In your browser visit
http://localhost:4200 and you should see “Welcome to Ember.js”
At this point you can put everything in your top level directory under version control:
git add .
gc -m "Initial commit"
Let’s make some modifications to our Rails app.
rm -rf rails/app/assets
rails/Gemfile remove the following:
Now everything related to the Asset Pipeline is completely removed.
Add the following to the
gem 'active_model_serializers', '0.9.3'
If you don’t have Postgres on your machine you can set this for Production only:
group :development, :test do
group :production do
bundle install in your
rails directory. Let’s commit our
git add -A
gc -m "Removed asset pipeline and added active_model_serializers in Rails"
That wraps up Part 1. In Part 2 will focus on Ember and creating some functionality in our app.
