Example of a Stamen tile source.

Two layers are composed: the watercolor base layer with the terrain labels.

main.js

import 'ol/ol.css';
import Map from 'ol/Map';
import Stamen from 'ol/source/Stamen';
import TileLayer from 'ol/layer/Tile';
import View from 'ol/View';
import {fromLonLat} from 'ol/proj';

const map = new Map({
  layers: [
    new TileLayer({
      source: new Stamen({
        layer: 'watercolor',
      }),
    }),
    new TileLayer({
      source: new Stamen({
        layer: 'terrain-labels',
      }),
    }),
  ],
  target: 'map',
  view: new View({
    center: fromLonLat([-122.416667, 37.783333]),
    zoom: 12,
  }),
});
