Creating Reusable code in Rails: Plugins, Metaprogramming, and Best Practices

Rails developers can improve code quality through plugins, metaprogramming, and DRY principles. Plugins allow extraction of reusable functionality, while metaprogramming helps generate dynamic methods to reduce repetition. These techniques enhance maintainability, readability, and reusability of code. By centralizing common patterns and abstracting them away, developers can create more efficient and scalable Rails applications. These practices are particularly useful for internal tools and open-source libraries.
