Be carefull not mixing these design principles

Atomic Design breaks the UI into small reusable pieces and builds

Atoms → buttons, inputs, icons, text

Molecules → small combinations (label + input, search bar)

Organisms → complex UI blocks (forms, headers, cards)

Templates → layout without real data

Pages / Screens → real data, API calls, navigation

Feature-Based Design: Business-Oriented Structure

Feature-Based architecture organizes code around business features instead of UI types.

Layer-Based Design: Simple but Limited

Layer-Based architecture groups code by technical layers: components hooks services utils
