ip-address-tracker using react.js

For me the tricky bits were -

Including a div with a fixed class name ('leaflet-container') while using CSS modules which normally decorates the class names.

Figuring out how to cause the map to update to a new location.

Styling the background images was a little tricky, I didn't realise I had to style the img element inside the picture element.

Getting the input element to resize properly from inside a flex-box.

Getting the vertical separator bars between the list of geo-location data.
