Feature-based code organization groups files by domain or feature rather than file type. This approach isolates features, minimizes cross-feature dependencies, and supports unidirectional data flow to keep medium-to-large React codebases maintainable.

Structure scalable React and Next.js codebases using a top-level src layout with app, features, and shared directories. Place API, UI, and utility code in dedicated folders to enforce clear feature boundaries and maintain cohesive code.

Use a feature-based project structure for medium-to-large codebases requiring feature isolation, unidirectional data flow, and maintainable team collaboration. Grouping by file type works for smaller apps but creates cross-feature dependencies at scale.

The best way to organize TypeScript frontend architecture for team collaboration is adopting a feature-based top-level structure. Clear feature boundaries and consistent organization patterns improve onboarding and minimize cross-feature dependencies.

In a feature-based React architecture, API calls and utilities belong in shared top-level directories like lib, hooks, and utils, while feature-specific API and UI code stays within isolated folders under the features directory.

A feature-based folder structure is designed for medium-to-large codebases that require feature isolation and unidirectional data flow. Small frontend applications may find this level of organization unnecessarily complex.
