Example of a translate features interaction.

This example demonstrates how the translate and select interactions can be used together. Zoom in to an area of interest and click to select a feature. Then drag the feature around to move it elsewhere on the map.

import 'ol/ol.css';
import GeoJSON from 'ol/format/GeoJSON';
import Map from 'ol/Map';
import OSM from 'ol/source/OSM';
import VectorSource from 'ol/source/Vector';
import View from 'ol/View';
import {
  Select,
  Translate,
  defaults as defaultInteractions,
} from 'ol/interaction';
import {Tile as TileLayer, Vector as VectorLayer} from 'ol/layer';

var raster = new TileLayer({
  source: new OSM(),
});

var vector = new VectorLayer({
  source: new VectorSource({
    url: 'data/geojson/countries.geojson',
    format: new GeoJSON(),
  }),
});

var select = new Select();

var translate = new Translate({
  features: select.getFeatures(),
});

var map = new Map({
  interactions: defaultInteractions().extend([select, translate]),
  layers: [raster, vector],
  target: 'map',
  view: new View({
    center: [0, 0],
    zoom: 2,
  }),
});
