Example on how to use turf.js with OpenLayers.

Example showing the integration of turf.js with OpenLayers. The turf.js function `along` is used to display a marker every 200 meters along a street.

##### main.js

    import {along} from '@turf/along';
    import {length} from '@turf/length';
    import Map from 'ol/Map.js';
    import View from 'ol/View.js';
    import GeoJSON from 'ol/format/GeoJSON.js';
    import TileLayer from 'ol/layer/Tile.js';
    import VectorLayer from 'ol/layer/Vector.js';
    import {fromLonLat} from 'ol/proj.js';
    import OSM from 'ol/source/OSM.js';
    import VectorSource from 'ol/source/Vector.js';

    const source = new VectorSource();
    fetch('data/geojson/roads-seoul.geojson')
      .then(function (response) {
        return response.json();
      })
      .then(function (json) {
        const format = new GeoJSON();
        const features = format.readFeatures(json);
        const street = features[0];

        // convert to a turf.js feature
        const turfLine = format.writeFeatureObject(street);

        // show a marker every 200 meters
        const distance = 0.2;

        // get the line length in kilometers
        const lineLength = length(turfLine, {units: 'kilometers'});
        for (let i = 1; i <= lineLength / distance; i++) {
          const turfPoint = along(turfLine, i * distance, {units: 'kilometers'});

          // convert the generated point to a OpenLayers feature
          const marker = format.readFeature(turfPoint);
          marker.getGeometry().transform('EPSG:4326', 'EPSG:3857');
          source.addFeature(marker);
        }

        street.getGeometry().transform('EPSG:4326', 'EPSG:3857');
        source.addFeature(street);
      });
    const vectorLayer = new VectorLayer({
      source: source,
    });

    const rasterLayer = new TileLayer({
      source: new OSM(),
    });

    const map = new Map({
      layers: [rasterLayer, vectorLayer],
      target: document.getElementById('map'),
      view: new View({
        center: fromLonLat([126.980366, 37.52654]),
        zoom: 15,
      }),
    });
