Our Rails Upgrade Process: How to bundle update rails

We know that there are many challenges involved in a Rails upgrade project. Depending on how big your application is, how old your Rails version is and how well structured your code is, it can be difficult to perform that job and keep your sanity. If you don't find a reliable and trustable process to guide you from version X to version Y, you can end-up in a nightmare.

The good news is that here at Ombu Labs, we have been upgrading Rails applications for over 10 years now and this gave us a know-how to define a process that has proven to be very effective. And today I want to share Our Rails Upgrade Process with you.

Gemifying your style guide to DRY your CSS

At Ombu Labs we like to follow a style guide to drive our own products. A style guide is a document that provides guidelines for the way your brand should be presented from both a graphic and language perspective. You can see Fast Ruby's style guide at this link.

Since we have a few applications in place and it's important to make sure that they all use the same style, we need to ensure that they will all inherit the same CSS files. One way to do this is to copy the above style guide and paste it inside all of our apps, but this would end up causing a lot of duplicated code. If we decided to change the font-style, for example, we would need to change it in all apps individually.

Something else we are super fans of at Ombu Labs is to follow good code and development practices. One of our favorites is the DRY (Don’t Repeat Yourself) principle, which states that duplication in logic should be eliminated via abstraction. So to avoid the duplicated code here, we decided to create a gem to encapsulate our style guide and to be bundled in all of our products.

In this article, I'll show you how we did it!
