Learn the refactorings, patterns, and best practices that will let you ship quickly even as your Rails app matures.
If you’ve worked on a Rails app for a while, chances are you’ve seen your development speed slow down.
Some of this is inevitable-as the number of features goes up, adding more tends to get harder. However, smart programming decisions can delay this slowdown, and that’s what this course is all about.
I’ve been writing and maintaining Rails apps for 8 years (including 6 at thoughtbot). This course contains the hard-won wisdom I wish I’d had when I got started.
Refactoring Rails contains three types of lessons:
Refactoring techniques you can apply today to help with the specific pains you’re facing.
