Feature-Based Folder Structures
Learn how feature-first folder structures help React applications grow predictably by grouping UI, logic, and state by domain rather than file type.
As React applications scale, codebases organized by file type rather than by feature become harder to maintain. A type-based structure spreads related logic across multiple folders, which complicates refactoring and introduces hidden dependencies that only surface at scale. Many React projects start with a structure that groups files by type. For example, a common structure looks like this:
