Advanced tools
Package description
The @types/react package contains TypeScript type definitions for React (a JavaScript library for building user interfaces). It enables TypeScript developers to use React with type checking, which enhances development by catching errors early and providing autocompletion in code editors. This package is essential for developers working with React in TypeScript projects, as it defines the types for React APIs, components, hooks, and other utilities.
Component Type Definitions
Defines TypeScript types for React functional components, allowing for type checking of props.
import React from 'react';
interface Props {
greeting: string;
}
const Greeting: React.FC<Props> = ({ greeting }) => <div>{greeting}</div>;
Hook Type Definitions
Provides type definitions for React hooks like useState, enabling type checking and autocompletion for hook-related code.
import React, { useState } from 'react';
const Counter: React.FC = () => {
const [count, setCount] = useState<number>(0);
return (
<div>
<p>{count}</p>
<button onClick={() => setCount(count + 1)}>Increment</button>
</div>
);
};
Event Type Definitions
Includes type definitions for handling events in React, such as mouse and keyboard events, with appropriate type checking.
import React from 'react';
const Clicker: React.FC = () => {
const handleClick = (event: React.MouseEvent<HTMLButtonElement>) => {
console.log('Button clicked');
};
return <button onClick={handleClick}>Click Me</button>;
};
Provides TypeScript definitions for React DOM, similar to @types/react but specifically for DOM-related types. It's used alongside @types/react for web development.
Offers TypeScript definitions for React Router DOM, a library for routing in React applications. It complements @types/react by adding types for routing components and hooks.
Contains TypeScript definitions for Redux, a state management library often used with React. It provides types for Redux's store, actions, and reducers, enabling type-safe state management in React apps.
