# @types/react-dom
`@types/react-dom`
is a TypeScript definition package from the DefinitelyTyped project that provides type information for the [react-dom](https://www.google.com/search?client=ubuntu-sn&channel=fs&q=react-dom&mstk=AUtExfD0el60w1UFWrdjeaK66vjv8Sx85mg1MsIt7NfrYdqoGPsoINnouUlHZXMXzYJQEYwcs4ZHYmlczfkbRKxI1XWIZgAYzCpG8HQR-8uHsIHiOxQSbnUf6iITch5hQoIELCJlu0xFkG1XQJ2diJ_bUazfnDYrxiZP_Ji8VR--TAzslrvM-A7501A9j-6CtrNQpv8EsN68T8XVWgwlHOVP6O0NFbNaODrv2nwKY6IwBMjfZ1V4Hdz5AxkN5d4_e0TFbLVW1EbcEnjMa1PKlnUXQMB0&csui=3&ved=2ahUKEwiYsdP-n7CRAxX5S2wGHawMMCQQgK4QegQIARAC) 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-dom` APIs.
- **Server-Side Rendering (SSR)**: Includes types for `ReactDOMServer` for SSR scenarios.
**Installation**
```
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
