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 BSD 2-Clause License.

Getting Started

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}{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:


OpenLayers appreciates contributions of all kinds. We especially want to thank our fiscal sponsors who contribute to ongoing project maintenance.

IntelliSense support and type checking for VS Code

The ol package contains a src/ folder with JSDoc annotated sources. TypeScript can get type definitions from these sources with a jsconfig.json config file in the project root:

  "compilerOptions": {
    "checkJs": true,
    "baseUrl": "./",
    "paths": {
      "ol": ["node_modules/ol/src"],
      "ol/*": ["node_modules/ol/src/*"]
  "include": [

Project template with this configuration:

Note that the above only works when authoring in plain JavaScript. For similar configurations with a tsconfig.json in TypeScript projects, your mileage may vary. You may want to use a third-party types package in this case.

Supported Browsers

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.
