When creating a React application, naming your components is an essential aspect of the development process. Proper component naming can make your code more organized, readable, and maintainable. In this post, we will explore the best practices for naming React components in 2023.
Start with a Capital Letter
// Correct function MyComponent() { return <div>Hello World</div>; } // Incorrect function myComponent() { return <div>Hello World</div>; }
Use Descriptive and Meaningful Names
// Good function SubmitButton() { return <button type="submit">Submit</button>; } // Bad function Btn() { return <button type="submit">Submit</button>; }
Use CamelCase
// Good function TodoList() { return ( <ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> </ul> ); } // Bad function todolist() { return ( <ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> </ul> ); }
Avoid Using DOM Component Names
// Good function Card() { return <div>This is a card</div>; } // Bad function div() { return <div>This is a card</div>; }
Be Consistent
// Good function Modal() { return <div>Modal content</div>; } function ModalHeader() { return <div>Modal header</div>; } // Bad function Modal() { return <div>Modal content</div>; } function HeaderModal() { return <div>Modal header</div>; }
Use Prefixes for Common Components
// Good function TableHeader() { return ( <thead> <tr> <th>Column 1</th> <th>Column 2</th> <th>Column 3</th> </tr> </thead> ); } // Bad function Header() { return ( <thead> <tr> <th>Column 1</th> <th>Column 2</th> <th>Column 3</th> </tr> </thead> ); }
Use Suffixes for Variations of the Same Component
// Good function ButtonPrimary() { return <button className="primary">Primary</button>; } function ButtonSecondary() { return <button className="secondary">Secondary</button>; } // Bad function PrimaryButton() { return <button className="primary">Primary</button>; } function SecondaryButton() { return <button className="secondary">Secondary</button>; }
Keep it Simple
// Good function Header() { return <h1>Welcome to my app</h1>; } // Bad function MySuperCoolAndAmazingHeader() { return <h1>Welcome to my app</h1>; }
