2-way data binding in native web components

I read on web components and am quite intrigued by the nascent specification. Does anyone know if there is support for two-way data binding in the DOM without using Polymer? An example will be appreciated.

No, data binding is not part of the web component specification.

You can, of course, implement data binding using your own JavaScript event listeners and possibly Proxy , but it's probably best not to reinvent the wheel: if you want to bind data, choose one of the many JavaScript frameworks that supports this. Polymer, React, Angular, and Vue are some recent examples of such libraries.

Object.observe is a potential new way to create data bindings in javascript. This feature is planned for Ecmascript 7 (javascript), but some browsers currently support it, check here . Also check this html5rocks article on object.observe
