ADR-11 Use-Directory-Structure

Context

A defined directory structure is required so that all developers know where to look for certain files in the frontend and backend.

Decision

The structure in the backend and EAI is feature-oriented, except for common packages (e.g. common, security, util, etc.). This means that all files related to a specific feature (e.g. budget, user, etc.) are in the same parent directory.

In the frontend, the structure is layer-oriented, meaning that all files of the same type (e.g. components, services, etc.) are in the same parent directory. In these directories, files can be further organized by feature.

Consequences

• In a feature-oriented structure, comparing entities or controllers can be harder since they are in separate directories.
• There is no central overview of all classes of the same type in the backend, as they are distributed across feature folders.
• However, it is helpful when working on a specific feature, as all necessary classes are in the same directory.
