Failed to load the resource: Error has something to do with Access Control Allow Origin

[davidfufu]

I'm using react and I have the example code in my return function.

		console.log(FBPostData);
		var stream = new Stream({
		    consumer_key: 'RHs4GdqsGH7QvTioGk3G3Tsf4',
		    consumer_secret: 'zPoZrZD9YqCH51FF0R5oQU8EJOX0IMz1JbwxY64Z44dT2u4pqE',
		    access_token_key: '	140915034-ckBaxPhhILbVyIeiYvMpyuPF9dx3ZbqxL5nrPBNE',
		    access_token_secret: 'fbAAa6LxYLjCN4MCeOj5uEpQVvqeKXbrk36o3bq1IkEza'
		});

		//create stream
		stream.stream();

		//listen stream data
		stream.on('data', function(json) {
		  console.log(json);
		});
		stream.on('error', function(err) {
		  console.log(err);
		});

The error that it returns is:

Twitter:1 Failed to load https://userstream.twitter.com/1.1/user.json: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access. The response had HTTP status code 400. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
