project-structure

Structure a React and Next.js project by creating top-level directories like src/app, src/features, and src/components. This feature-based architecture organizes code by domain modules rather than file type, keeping your codebase scalable and maintainable as it grows.

Feature-based architecture in TypeScript applications is a code organization pattern that groups files by domain modules. It defines self-contained feature folders with clear boundaries, preventing cross-feature coupling and ensuring modules remain isolated and maintainable.

Prevent circular dependencies in a Next.js codebase by enforcing unidirectional import directions. This pattern restricts feature modules from importing each other directly, guiding shared code into designated folders like src/lib and src/utils to improve overall composability.

Yes, the feature-based architecture pattern works for existing codebases. You can reorganize your current project by migrating code into top-level structures like src/features and src/components, establishing clear boundaries to reduce coupling during the transition.

The best way to organize shared vs feature code in React is to place reusable UI elements in src/components and domain-specific logic in src/features. This separation enforces unidirectional imports and prevents feature modules from directly depending on one another.

Avoid barrel files in a TypeScript project structure because they often introduce circular dependencies and unnecessary coupling. Enforcing unidirectional imports and specifying concrete placement rules for shared code helps maintain strict feature module isolation.
