🔷 React.js Project Folder Structure Explained (Vite + JSX Setup) 🔷
Welcome to this beginner-friendly guide where I walk you through the folder structure of a modern React.js project built using Vite!
In this video, we’ll explore the contents of the project directory named FIRSTAPP, and understand the purpose of each file and folder. Whether you're just getting started with React or want to follow best practices in naming and organizing your project, this video is for you!
🚀 Project Folder Overview:
FIRSTAPP/
├── node_modules/ # Auto-generated dependencies folder
├── public/ # Static assets like images, favicon
├── src/ # Source code lives here
│ ├── assets/ # (Optional) Folder for images, fonts, icons etc.
│ ├── App.css # Styling for App component
│ ├── App.jsx # Main App component
│ ├── index.css # Global CSS
│ └── main.jsx # App entry point (renders App component)
├── .eslintrc.cjs # ESLint config file for code linting
├── .gitignore # Git ignore rules
├── index.html # HTML template injected by Vite
├── package.json # Project metadata + scripts + dependencies
├── package-lock.json # Exact version tree for dependencies
├── README.md # Project documentation
└── vite.config.js # Vite build and dev server configuration
📌 Naming Convention Rules (Best Practices):
✅ Folders:
Lowercase with hyphens or camelCase (e.g., src, assets)
Group related files (e.g., components, pages, utils)
✅ Files:
Components: PascalCase (e.g., App.jsx, MainLayout.jsx)
Stylesheets: Match component name (e.g., App.css)
Utility/helper files: camelCase (e.g., fetchData.js)
✅ JSX Files:
Use .jsx for files that return JSX
Entry files like main.jsx and App.jsx should be clearly named
✅ CSS Files:
Keep global styles in index.css
Component-specific styles can be kept alongside the component
✅ Configuration Files:
Start with dot (.) like .eslintrc.cjs, .gitignore
Keep at root for visibility
💡 Whether you're building a personal project or preparing for interviews, having a clean and consistent folder structure is crucial for scaling and collaboration.
