Recommended src Structure

Growing the Project

src/
├── components/   reusable UI (Button, Modal, Navbar)
├── pages/        one component per route (Home, Login, Dashboard)
├── hooks/        custom hooks (useFetch, useDebounce)
├── context/      React context providers (AuthContext)
├── services/     API calls (api.js)
├── store/        Redux / state management
├── utils/        helper functions
├── App.jsx
└── main.jsx

Tip: Keep a component, its CSS and its test together in one folder when the project gets big.
