OpenLayers is a high-performance, feature-packed library for creating interactive maps on the web. It can display map tiles, vector data and markers loaded from any source on any web page. OpenLayers has been developed to further the use of geographic information of all kinds. It is completely free, Open Source JavaScript, released under the 2-clause BSD License (also known as the FreeBSD).
Install the ol package:
npm install ol
Import just what you need for your application:
import Map from 'ol/Map';
import View from 'ol/View';
import TileLayer from 'ol/layer/Tile';
import XYZ from 'ol/source/XYZ';
new Map({
target: 'map',
layers: [
new TileLayer({
source: new XYZ({
url: 'https://{a-c}.tile.openstreetmap.org/{z}/{x}/{y}.png'
})
})
],
view: new View({
center: [0, 0],
zoom: 2
})
});See the following examples for more detail on bundling OpenLayers with your application:
- Using Rollup
- Using Webpack
- Using Parcel
- Using Browserify
OpenLayers runs on all modern browsers that support HTML5 and ECMAScript 5. This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, polyfills for requestAnimationFrame and Element.prototype.classList are required, and using the KML format requires a polyfill for URL.
