Online Rails Development with Heroku

Posted by Timothy Fisher Mon, 17 Mar 2008 01:11:00 GMT

Heroku is a web application that provides a complete environment for writing Ruby on Rails powered web applications. With Heroku you get both a development environment and a hosting platform. Each application that you create with Heroku is also assigned a unique URL that you can use to access it.

Heroku has plenty of gems and Rails plugins pre-installed and available to any Rails application. However, if you want to use a gem or plugin that is not already installed, you can do that also. It is simple to install any gem or plugin into your Heroku Rails application. You can also upload a complete Rails application that you developed locally, into the Heroku environment. The opposite is also possible. You can export an application that you developed inside of Heroku and download its source to your local computer. As you write migrations, they are automatically detected and run without any manual intervention. You also get a built-in console for running any rake tasks that your application has. A built-in Rails console is also provided in a browser window.

Heroku also recently added an API that allows you to develop your Rails application locally on your computer and deploy to Heroku remotely through the Heroku API. The source code version control system that Heroku uses to store your source code is also exposed. The version control system used is GIT. If you have GIT installed locally you can directly access your application’s source code and make commits against it. When you want to deploy back to the Heroku servers, you do that through the Heroku API.

Heroku is probably not the host you’d select for deploying a production Rails application, but it can be a satisfactory development environment, and an excellent platform for learning. In a training environment, students would be able to develop a complete Rails application using only the Heroku web application without having to install any software on their computers. It is also easy to collaborate on an application using Heroku. Once you create an application, it is easy to add other users as collaboratorsruby who also have access to the application’s source code. Overall, I think this is a great tool that can help more people get exposure to the Rails platform.
