No ‘Access-Control-Allow-Origin’ header is present on the requested resource error

by

If you use Google Chrome browser you can hack with an extension.

You can find a Chrome extension that will modify CORS headers on the fly in your application. Obviously, this is Chrome only, but I like that it works with zero changes anywhere at all.

You can use it for debugging your app on a local machine (if everything works in production).

Notice:
If URL becomes broken the extension name is Access-Control-Allow-Origin: *. I recommend you to disable this extension when you not working on your stuff, because, for example, youtube does not work with this extension.
