From 0.37.0 onwards there is a new feature in RN that might help you. There is a new prop in the WebView: onMessage and also a new method, postMessage that enable two-way communication. From the WebView, you have to call window.postMessage, and it will invoke the function that you define as callback for onMessage. You can see a full example in the documentation.
