project-structure

To organize code by feature, you group related components and APIs under dedicated feature folders within your src directory. This feature-based structure improves maintainability by establishing clear module boundaries and keeping domain-specific logic grouped together.

The best way to structure a scalable Next.js application is using a standard src layout divided into app, features, and shared utilities. This enforces unidirectional code flow to reduce cross-feature coupling as your project grows.

Feature-based architecture prevents cross-feature imports by defining strict module boundaries and enforcing unidirectional code flow. It complements ESLint rules to restrict dependencies, stopping one feature from directly importing another feature's internal code.

Yes, you can apply this feature-based structure to existing React project restructurings. It guides both top-level and feature-level folder layouts, helping you reorganize an existing codebase to improve maintainability during ongoing refactors.

You need to restructure your codebase into feature folders when maintainability drops due to cross-feature coupling. This approach organizes code by domain, making it easier to locate related components and plan where to place new code.

A limitation of a feature-based folder structure in TypeScript apps is the strict dependency management required. You must continuously enforce unidirectional code flow and ESLint rules to prevent cross-feature imports, which can introduce initial setup overhead.
