Testing

In a new development app I've added the following snippet to app/packs/decidim/decidim_application.js:

class SwisstopoMapController {
  start() {
    console.log('SwisstopoMapController start');
  }

  load() {
    console.log('SwisstopoMapController load');
  }

  setCoordinateReferenceSystem() {
    console.log('SwisstopoMapController setCoordinateReferenceSystem');
  }

  addTileLayers() {
    console.log('SwisstopoMapController addTileLayers');
  }

  setViewport() {
    console.log('SwisstopoMapController setViewport');
  }
}

$(() => {
  window.Decidim.createMapController = (mapId, config) => {
    return new SwisstopoMapController(mapId, config);
  }
})
