TypeScript Best Practices for React

TypeScript brings type safety to JavaScript, making it easier to build and maintain large-scale React applications.

Why TypeScript?

TypeScript provides:

• Type Safety: Catch errors at compile time
• Better IDE Support: Autocomplete and refactoring tools
• Self-Documenting Code: Types serve as documentation
• Improved Developer Experience: Better tooling and debugging

Essential Patterns

Component Props

Always define proper types for your component props:

interface ButtonProps {
  label: string;
  onClick: () => void;
  disabled?: boolean;
}

Hooks

Type your hooks properly:

const [count, setCount] = useState<number>(0);

Common Pitfalls

• Avoid using any type
• Use proper type inference where possible
• Leverage TypeScript's utility types

Conclusion

Following TypeScript best practices will help you build more maintainable and robust React applications.
