Introduction

React and TypeScript have become the go-to combination for building modern web applications. In this comprehensive guide, we'll explore how to set up a new project and implement best practices for scalable development.

Setting Up Your Development Environment

First, let's create a new React project with TypeScript using Vite:

npm create vite@latest my-app -- --template react-ts
cd my-app
npm install

Key Benefits of TypeScript in React

  1. Type Safety: Catch errors during development
  2. Better IDE Support: Enhanced autocomplete and refactoring
  3. Improved Maintainability: Self-documenting code
  4. Enhanced Component Props: Clear interface definitions

Example Component

Here's a simple example of a typed React component:

interface UserProfileProps {
  name: string;
  age: number;
  email: string;
  isAdmin?: boolean;
}

const UserProfile: React.FC<UserProfileProps> = ({ 
  name, 
  age, 
  email, 
  isAdmin = false 
}) => {
  return (
    <div className="user-profile">
      <h2>{name}</h2>
      <p>Age: {age}</p>
      <p>Email: {email}</p>
      {isAdmin && <span className="admin-badge">Admin User</span>}
    </div>
  );
};
