Modern Web Development with React and TypeScript

Learn how to build robust web applications using React and TypeScript, with best practices and modern tooling.
Modern web development has evolved significantly over the past decade.
React has emerged as one of the most popular libraries for building user interfaces, and TypeScript has become the language of choice for many developers.
When used together, they provide a powerful combination for building robust and maintainable web applications.
React is a JavaScript library for building user interfaces.
It was created by Facebook and is now maintained by Facebook and a community of individual developers and companies.
React allows developers to create reusable UI components and manage the state of those components efficiently. .
// A simple React functional component with TypeScript
interface ButtonProps {
text: string;
onClick: () => void;
variant?: 'primary' | 'secondary';
}
const Button: React.FC<ButtonProps> = ({ text, onClick, variant = 'primary' }) => {
return (
<button
className={`btn btn-${variant}`}
onClick={onClick}
>
{text}
</button>
);
};
TypeScript is a statically typed superset of JavaScript that adds optional types to the language.
It was developed by Microsoft and is designed to make JavaScript more scalable and maintainable.
TypeScript helps catch errors earlier in the development process and provides better tooling and IDE support. .
// TypeScript interface example
interface User {
id: number;
name: string;
email: string;
role: 'admin' | 'user' | 'guest';
metadata?: {
lastLogin: Date;
preferences: Record<string, unknown>;
};
}
// Using the interface
function getUserDisplayName(user: User): string {
return user.role === 'admin' ? `${user.name} (Admin)` : user.name;
}
When using React with TypeScript, you get the best of both worlds: the component-based architecture of React and the type safety of TypeScript.
This combination can help you write more robust code and catch errors before they make it to production. .
// Setting up a React project with TypeScript using Vite
// First, run this command in your terminal:
// npm create vite@latest my-app --template react-ts
// Then navigate to your project and install dependencies:
// cd my-app
// npm install
In this article, we'll explore best practices for using React with TypeScript and how to set up a modern development environment with tools like Vite, ESLint, and Prettier.
We'll also look at how to structure your project for maintainability and scalability.
By the end of this article, you should have a good understanding of how to build modern web applications using React and TypeScript, and be ready to apply these techniques to your own projects..
