Swipe and sync between two maps

Map movements are synced with mapbox-gl-sync-move.

var before = new mapboxgl.Map({
  container: 'before', // Container ID
  style: 'mapbox://styles/mapbox/light-v9'
});

var after = new mapboxgl.Map({
  container: 'after', // Container ID
  style: 'mapbox://styles/mapbox/dark-v9'
});

new mapboxgl.Compare(before, after, {
  mousemove: true // Optional. Set to true to enable swiping during cursor movement.
});

You'll need a Mapbox access token stored in localstorage. Set it via

localStorage.setItem('MapboxAccessToken', '<TOKEN HERE>');

Tests require an MapboxAccessToken env variable to be set.

export MapboxAccessToken="YOUR ACCESS TOKEN"

Lastly, run the test command from the console:

npm test
