The UMD builds of React and ReactDOM are available over a CDN.
<script crossorigin src="https://unpkg.com/react@16/umd/react.development.js"></script> <script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script>
The versions above are only meant for development, and are not suitable for production. Minified and optimized production versions of React are available at:
<script crossorigin src="https://unpkg.com/react@16/umd/react.production.min.js"></script> <script crossorigin src="https://unpkg.com/react-dom@16/umd/react-dom.production.min.js"></script>
To load a specific version of
16 with the version number.
If you serve React from a CDN, we recommend to keep the
crossorigin attribute set:
<script crossorigin src="..."></script>
We also recommend to verify that the CDN you are using sets the
Access-Control-Allow-Origin: * HTTP header:
This enables a better error handling experience in React 16 and later.
