Writing Loosely Coupled Code in Ruby on Rails
Best Practices and Techniques
Ruby on Rails is a model-view-controller (MVC) framework, providing default structures for a database, a web service, and web pages. One of the critical aspects of building maintainable and scalable applications in Rails — or any framework, for that matter — is writing loosely coupled code. Loosely coupled code refers to components or classes that are independent of each other, making the system more flexible, scalable, and easier to manage. This article explores best practices and techniques for writing loosely coupled code in Rails, ensuring your application remains robust and adaptable.
Understanding Coupling in Rails Applications
Coupling measures how closely connected two routines or modules are; the less they know about each other, the more loosely coupled they are. High coupling can lead to a fragile codebase that’s hard to test, maintain, and extend. Conversely, low coupling enhances modularity, making your codebase more resilient to changes and easier to understand.
