Engine-ering Rails apps

Rails applications tend to grow and turn into massive monoliths—that’s a natural evolution of a Rails app, isn’t it? What happens next is you start looking for an architectural solution to keep the codebase maintainable. Microservices? If you’re brave enough… Rails ecosystem already has the right tool for the job: engines. With the help of engines, you can split your application into independent parts combined under the same root application—the same way rails gem combines all its sub-frameworks, which are engines too, by the way.
