Using with Redux

If you're using redux, it is very easy to hook this component up to store state in the redux state tree. The simplest way is to take all properties passed to the onChangeViewport function property and add them directly into the store. This state can then be passed back to react-map-gl without any transformation.

You can use the package redux-map-gl to save writing this code yourself.
