This code demonstrates two ways of performing a signed upload to Cloudinary from the browser, using a server to create the signature. One uses Cloudinary's upload widget, the other uses a standard HTML form.

• Files specific to signed upload using Cloudinary's upload widget:
  • modules/signuploadwidget.js
  • public/uploadwidget.html
  • public/js/uploadclientwidget.js
  • routes/signuploadwidget.js
• Files specific to signed upload using a standard HTML form:
  • modules/signuploadform.js
  • public/uploadform.html
  • public/js/uploadclientform.js
  • routes/signuploadform.js

1. Install all dependencies from the top level:

   npm install

2. Open signed-uploads/public/js/config.js

3. Set cloud_name, api_key and api_secret with the corresponding account details from the API Keys page of the Console Settings.

4. Run the app to start the server:

   node signed-uploads/app.js

   The response should be:

   Server is up on http://localhost:3000

5. Open http://localhost:3000 in a browser.
