What is a recommended practice for module organization in Sitecore solutions with SXA?

In Sitecore solutions utilizing SXA (Sitecore Experience Accelerator), separating features into modules based on functionality is considered a best practice because it promotes organization and maintainability of the codebase. By structuring your modules around specific features, developers can more easily isolate, develop, and troubleshoot individual components. This modular approach enhances reusability and makes it more straightforward to manage dependencies and updates since each feature can evolve independently without affecting others.

Furthermore, this practice aligns with modern development principles such as Agile and DevOps, where quick iteration and deployment of specific functionalities are crucial. It encourages a clear separation of concerns, allowing development teams to work simultaneously on different features without stepping on each other's toes.

In contrast, organizing by type or grouping by layers tends to create a more monolithic structure, which can lead to complications during development and maintenance. Using modularity as the primary organizing principle is a broader concept; it does not specifically address framework best practices like the focused functionality approach does. Therefore, the choice of separating features into modules based on functionality supports a clean, efficient, and scalable development environment in Sitecore solutions.
