# TypeScript Best Practices for React Developers TypeScript brings type safety to JavaScript, making your React applications more robust and maintainable. Here are the best practices every React developer should know. ## Setting Up TypeScript with React Start with a TypeScript React project: ```bash npx create-react-app my-app --template typescript ``` ## Component Props Typing Always define interfaces for your component props: ```typescript interface ButtonProps { variant: 'primary' | 'secondary'; onClick: () => void; children: React.ReactNode; disabled?: boolean; } const Button: React.FC<ButtonProps> = ({ variant, onClick, children, disabled = false }) => { return ( <button className={`btn btn-${variant}`} onClick={onClick} disabled={disabled} > {children} </button> ); }; ``` ## State Typing with useState Be explicit about state types: ```typescript const [user, setUser] = useState<User | null>(null); const [loading, setLoading] = useState<boolean>(false); ```
