Chrome 56 .. whats new?

With Chrome 56, web apps can now communicate with nearby Bluetooth Low Energy devices using the Web Bluetooth API, position sticky is back – making it easy to create elements that scroll normally until sticking to the top of the viewport. And HTML5 by Default is enabled for all users.

Chrome 56 on iOS also adds the ability to scan QR codes directly within Chrome. So many thought QR-Codes were dead, well not so much !

Paw – essential HTTP client to test your APIs

Paw is a full-featured HTTP client that lets you test the APIs you build or consume. It has a beautiful native OS X interface to compose requests, inspect server responses and generate client code out-of-the-box.

This is one of my go-to tools, when test-driving my API endpoints.

	}
});

// Stream big file in worker thread
Papa.parse(bigFile, {
