Fit to a Bounding Box

Pass bounds and fitBoundsOptions to the map constructor to open already framed to a [[west, south], [east, north]] extent - here Switzerland - with no animation.

import { MaptoolkitLogoControl } from 'https://cdn.jsdelivr.net/npm/@maptoolkit/maplibre-gl-logo/+esm';
const map = new maplibregl.Map({
  container: 'map', attributionControl: { customAttribution: '' },
  style: 'https://styles.maptoolkit.org/summer.json',
  bounds: [[5.96, 45.82], [10.49, 47.81]], // Switzerland
  fitBoundsOptions: { padding: 20 }
});
map.addControl(new MaptoolkitLogoControl());
