Best Practices
Type Safety
TypeScript enhances React development by providing type safety and better developer experience.
Component Props
Always define interfaces
for your component props:
typescript
3interface ButtonProps {
4 children: React.ReactNode;
5 onClick: () => void;
6 variant?: 'primary' | 'secondary';
7}
8
9const Button: React.FC<ButtonProps> = ({ children, onClick, variant = 'primary' }) => {
10 return (
11 <button onClick={onClick} className={variant}>
12 {children}
13 </button>
14 );
15};
State Management
Use proper typing for useState
:
typescript
3const [user, setUser] = useState<User | null>(null);
These practices help catch errors early and improve code maintainability.
