To enforce feature-based architecture in a Next.js project, apply colocation of related code into feature folders and separate layers across app, features, shared, and config directories. This structure reduces coupling and improves modularity.

Preventing cross-feature dependencies in TypeScript requires using index.ts barrels as public API contracts. This exposes stable module surfaces and restricts direct access to internal feature files, maintaining clear boundaries.

Structure a multi-feature Next.js repository for scalable collaboration by dividing code into app, features, shared, and config layers. This layer separation enforces clear boundaries and predictable code organization across teams.

This architecture governance approach does not require specific Next.js configurations. It applies structural constraints directly to your repository by organizing colocated files and defining public API barrels within your feature folders.

Use public API barrels in a feature-based folder structure when you need to expose stable module surfaces. Index.ts barrels prevent cross-feature dependencies and enforce clear architectural boundaries across your codebase.

Layer separation matters for multi-feature TypeScript repositories because it reduces coupling between app, features, shared, and config layers. Enforcing these clear boundaries enables predictable collaboration and easier long-term maintenance.
