AngularJS and Ruby on Rails work together

Finding the best integration of AngularJS and Ruby on Rails

Recently I got really excited with AngularJS so to make it work perfectly with Ruby on Rails there are some configurations needed. There are available blog posts on how to integrate it perfectly but somehow I wasn’t happy with the available preferences. Some offered to add the javascript files manually to the project and to manual project organization, others offered some kind of gem packager or even automated as a rails app template.

My goal is to describe how to start new rails app project from the scratch but the instructions should be succinct enough to be able to reuse them for the existing project (Actually I did extract it from the existing application I am working on). For the front end development I recently discovered great gem that really can make it more closer to pure full stack javascript development.
Bower is a great javascript package manager by the people who are working on Twitter Boostrap. It is like Bundler but made for javascript instead of ruby language. When I found out that there is a ruby gem that is integrated with rake tasks so I can easily update all javascript libraries without needing adding gem library for each one. The gem is called bower-rails.

My initial plan is to evolve this post into a series of blog posts on how to develop a fully functional demo application so I’ve included some steps that are might not needed but are good to have. Don’t worry I will provide explanation why I am using each of them.
Here is my plan what I will try to achieve with this series of posts:

  • creating a new¬†demo project with angularJS from scratch, showing all my changes along the way, and trying to explain every step. this will include creating basic rails 4 app
  • adding basic gems
  • setup front end development with Bower
  • adding angularJS
  • implementing basic Rails and AngularJS controllers
