AuthenticatedFormDataUploader class

This is a custom data provider that uses a pre-shared token to sign a short lived jwt token and send it as a bearer token to the endpoint. On the server side you can then verify the token using this kind of code:

Signature:

declare class AuthenticatedFormDataUploader extends BaseFormDataUploader 

Extends: BaseFormDataUploader

Example

try {
  // Otherwise let's validate the token.
  const { exp } = verify(token, env.JWT_SECRET);
  // Tokens cannot be expired or have a duration that's more than
  // 600 seconds into the future.
  if (exp < Date.now() / 1000 || exp - Date.now() / 1000 > 600) {
    // If the token is expired then it's no good
    return new Response("Unauthorized", { status: 401, headers: cors });
  }
} catch (error) {
  console.error(error);
  return new Response("Unauthorized", { status: 401, headers: cors });
}

and then forward the request to a pinata or other endpoint for the final upload.
