@mapbox/mapbox-gl-sync-move 

Sync movement between two or more Mapbox GL JS maps.

Install

``
npm install @mapbox/mapbox-gl-sync-move
`

Usage

This module exports a function that receives as arguments two or more Mapbox GL JS maps whose movements you'd like to sync.

`js
var mapboxgl = require('mapbox-gl');
var syncMaps = require('mapbox-gl-sync-move');

var mapA = new mapboxgl.Map(..);
var mapB = new mapboxgl.Map(..);

syncMaps(mapA, mapB);
`

Developing

There are unit tests with mocked maps, and there's a page for manual testing.

Run the unit tests with npm test.

To manually test, ensure you have a MapboxAccessToken environment variable set. Then start the server with npm run start`.
