Once the bundler is installed, we’re almost ready to start the gem making process. Rails is the project where Bundler’s most well-known usage occurs, but we can also use Bundler –not only for gem dependency management– but also for writing our own gems.
Our first step is to get bundler installed.

If we want to use that code elsewhere or want to share it, that’s when it’s time to make a gem.Ī gem is easy to build and more than likely, the tools needed to create them have already been installed in your environment. So why create a gem? Gems are a helpful byproduct created when you either have a piece of code that gets broken out to stand alone or else when a developer realizes this bit of code might actually be helpful to others. The code required for a gem will still be a part of our project’s ecosystem, but we will ultimately remove some overhead –and avoid unnecessary duplication– by using a gem instead of coding it all up on our own. Like the plugins that came before them, gems are mini-pieces of code used to perform specific duties without interfering with or becoming a direct part of our code. As the name implies, the Ruby programming language thrives thanks to the presence of gems.
