Getting Started

MapQuest.js is a JavaScript library for interactive maps, geocoding, directions, and traffic. MapQuest.js is powered by the MapQuest APIs and integrates with Leaflet.js.

To get started, first include MapQuest.js and MapQuest.css in your HTML header.

<script src=""></script>
<link type="text/css" rel="stylesheet" href=""/>

Then initialize your MapQuest key and define a MapQuest map object with a center, layer, and zoom.

L.mapquest.key = 'KEY';

// 'map' refers to a <div> element with the ID map'map', {
  center: [37.7749, -122.4194],
  layers: L.mapquest.tileLayer('map'),
  zoom: 12

MapQuest.js Maps

If you only want to display maps, and reduce the size of the bundle, use the maps only version of the MapQuest.js library.

<script src=""></script>
<link type="text/css" rel="stylesheet" href=""/>

MapQuest.js Core

By default, MapQuest.js includes a bundled version of Leaflet v1.3.1 that is fully supported. If you only want to use a different version of Leaflet, use the core version of the MapQuest.js library.

<script src="your version of Leaflet.js"></script>
<link type="text/css" rel="stylesheet" href="your version of Leaflet.css"/>
<script src=""></script>
<link type="text/css" rel="stylesheet" href=""/>
