React image and video upload

When using the React SDK, you can use one of the following methods to upload files directly to Cloudinary without the need for server-side operations or authentication signatures:

• Upload widget: A ready-made, responsive user interface that enables your users to upload files from a variety of sources directly to Cloudinary. This UI can be easily customized and embedded within your web application with just a few lines of code.

  
  

• Upload endpoint: https://api.cloudinary.com/v1_1/${cloudName}/upload. To use the endpoint in your application, write a function that calls the Cloudinary upload endpoint and pass:

  • an unsigned upload preset with the upload method options you want to apply for all files
  • the file(s) to upload
  • other unsigned upload parameters to apply to the selected files (e.g. tags, if needed)

• jQuery SDK with Blueimp File Upload adapter: If you are using jQuery in your app, you can take advantage of the built-in upload functionality in Cloudinary's jQuery SDK. This solution uses modern HTML5 cross-origin resource sharing (CORS) and gracefully degrades to a seamless iframe based solution for older browsers.
