@types/react-dom
@types/react-domis a TypeScript definition package from the DefinitelyTyped project that provides type information for the react-dom library, essential for building React apps with TypeScript to get autocompletion and type safety for DOM-specific React functions like ReactDOM.render() and server-side rendering methods, installed via npm or yarn alongside react and @types/react.
Purpose & Use
- Type Definitions: Adds static types for
react-dom, allowing TypeScript to understand functions, properties, and return types for DOM manipulation within React. - TypeScript Integration: Crucial for TypeScript projects using React, providing IntelliSense and error checking for
react-domAPIs. - Server-Side Rendering (SSR): Includes types for
ReactDOMServerfor SSR scenarios.
Installation
bash
npm install --save-dev @types/react @types/react-dom
# or
yarn add -D @types/react @types/react-dom
Note: You'll typically install
@types/react and @types/react-dom together for a full setup. Key Exports
ReactDOM: For client-side rendering (e.g.,ReactDOM.createRoot()).ReactDOMServer: For server-side rendering (e.g.,ReactDOMServer.renderToString()).
How it Works
When you use React with TypeScript,
@types/react-dom (and @types/react) provides the "contracts" for how these libraries work, ensuring you're using them correctly and catching potential bugs before runtime
