Where inside your solution architecture should the JSS code be housed when working with a team of JSS developers?

In a solution architecture where multiple developers are working on a JavaScript Services (JSS) project, housing the JSS code in the project layer is a strategic choice. The project layer serves as the area where all project-specific components and configurations reside, making it the most logical location for the JSS code.

The project layer typically contains elements that are unique to the specific application or project, such as custom components, configurations, and business logic that directly pertain to that project. Since JSS is intended to facilitate front-end development with Sitecore by allowing developers to build applications using modern JavaScript frameworks, housing it in the project layer ensures that all JSS components are closely aligned with the project’s objectives and features.

The feature layer is generally used for reusable functionality across multiple projects, while the foundation layer accommodates shared codebase utilities and services. The environment layer is concerned with infrastructure-specific setups and configurations. Keeping JSS code at the project level allows a team of developers to work collaboratively while maintaining clarity about which components and functionalities belong to the specific project at hand. This organization enhances the maintainability and scalability of the application's architecture.
