Are you familiar with Feature-Sliced Design (FSD)?

Feature-Sliced Design (FSD) is an architectural approach to organizing frontend code, focused on dividing the application into functional slices (features). Unlike traditional approaches, where code is divided by type (components, services, utilities), FSD structures the project around business functions.

Main ideas of FSD:

• Features as the basis of the structure: each feature contains everything necessary for its operation — components, logic, styles.
• Clear boundaries: minimizing connections between features, which facilitates maintenance and scaling.
• Levels of nesting: features can contain sub-features, helping organize complex modules.

Example structure:

src/
  entities/    # business entities
  features/    # functional capabilities
  shared/      # common components and utilities
  widgets/     # composite UI blocks

FSD helps create scalable and maintainable applications, especially in large teams.
