repository-structure

Repository structure organizes code into clear layers—UI, service, and data—with defined directory roles, naming conventions, and dependency rules. A well-designed structure from the start reduces refactoring friction as your project grows and helps teams maintain consistency across modules.

Test placement follows layer boundaries: unit tests colocate with source modules, integration tests sit in a dedicated layer, and end-to-end tests live at the top. This layout mirrors your architecture and makes test selection and maintenance predictable as projects scale.

Yes. Repository structure updates work on both new and existing projects. Document your current layout, align it with layer-based guidelines, and refactor incrementally without disrupting active development, using the structure document as a governance reference.

Naming conventions standardize how you name directories, files, and modules within each layer to enforce clarity and reduce cognitive load. The structure document specifies conventions per layer—service names, utility prefixes, test suffixes—ensuring consistent discovery and navigation.

Module boundaries separate concerns by layer and responsibility; dependency rules prevent circular imports and enforce one-way flows. Document which layers can depend on which others, specify what each module exports, and use the repository structure document to enforce these rules during code review.

The output is a docs/repository-structure.md file that standardizes project organization, specifies directory roles, naming patterns, test layouts, and dependency governance. Teams reference this document for onboarding, architecture decisions, and scaling decisions.
