1. Use PascalCase for Component Names
- Component names should start with a capital letter and use PascalCase. This helps differentiate components from standard HTML elements.
- Example:
js function UserProfile() { return <div>Profile</div>; }
2. Descriptive and Meaningful Names
- The name should reflect the purpose of the component. It should give a clear indication of what the component does or represents.
- Example:
js function LoginForm() { return <form>Login</form>; }
3. Use Prefixes for Reusable Components
- When creating reusable components, use a prefix like
ButtonPrimary
orInputText
to indicate its role and context. - Example:
js function ButtonPrimary() { return <button>Primary Button</button>; }
4. Avoid Abbreviations
- Avoid using abbreviations that might not be clear to everyone. Full words improve readability.
- Example:
js function NotificationCard() { return <div>Notification</div>; }
5. Keep Component Names Singular
- Name components in the singular form unless the component logically represents a collection.
- Example:
js function ProductList() { return <ul>{/* List of products */}</ul>; }
6. Use Compound Words for Specialized Components
- For components with specialized functionality, combine words to reflect their purpose.
- Example:
js function UserProfilePicture() { return <img src="profile.jpg" alt="Profile" />; }
7. Avoid Including “Component” in the Name
- It’s generally unnecessary to append “Component” to your component names, as it adds redundancy.
- Example:
js function Header() { return <header>Header Section</header>; }
8. Higher-Order Components (HOCs)
- When creating higher-order components, prefix the name with
with
or a similar word to show it enhances another component. - Example:
js function withAuth(WrappedComponent) { return function EnhancedComponent(props) { return <WrappedComponent {...props} />; }; }
9. Functional or Class Component Names
- Use a consistent naming convention based on the type of component (class or function). Even though functional components are more common, the naming should be clear.
- Example:
js function Navbar() { return <nav>Navbar</nav>; }
Following these best practices helps maintain clarity, consistency, and readability in your React projects.
