Why Bundler?

Fri Sep 10 03:22:37 -0700 2010

I have moved all of my Rails applications, and every client application I am consulting for over to Bundler and using Gemfiles, and you should too.

All of my Rails 3 AND Rails 2.x applications are now running on Bundler. Even a Rails 2.1 app that we are in the process of upgrading is running on Bundler, or at least using bundler for dependency management and configuration.

Bundler is NOT some “Rails 3 thing” and if you have this misconception, it is time you wrapped that up into a small scruntchy ball and tossed it into the circular file.

But some people try to install Bundler and report back to me “It’s too hard” or “It doesn’t work” and “It broke my app”. Of course, in many cases, you have to configure your code correctly, but the GemBundler site is full of information to do that.

But once your application or ruby code is configured to use Bundler, the crazy thing is that about 9 times out of 10, any further problems is because Bundler has found a problem with your gem dependencies that you didn’t even know you had.

I have had many many people talk to me about Bundler, in good and bad ways, and usually, any negative comments come from a lack of understanding on why bundler, and why it is needed.

Luckily, Yehuda was recently at EuRuKo in Karkow, and did this talk on Why Bundler? If you haven’t watched it yet, it is very well worth your time to sit through. Many things will become clear.

Oh, and a parting tip, if you are trying to get Rails 2.1 running with bundler, just configure bundler as if it was not a Rails Framework app. Treat it like the Sinatra app examples on the Gembundler website.

    Bundler? I do not like it. I do not know how you can use it.
