<div class="announcement">Jun 27, 2017 — <a href="/2017/08/08/leaflet-1.2.0.html">Leaflet 1.2.0</a> has been released.</div>
|
|
|
|
<p>Leaflet is the leading open-source JavaScript library for mobile-friendly interactive maps.
|
|
Weighing just about <abbr title="38 KB gzipped — that's 133 KB minified and 378 KB in the source form, with 10 KB of CSS (2 KB gzipped) and 11 KB of images.">38 KB of JS</abbr>,
|
|
it has all the mapping <a href="#features">features</a> most developers ever need.</p>
|
|
|
|
<p>Leaflet is designed with <em>simplicity</em>, <em>performance</em> and <em>usability</em> in mind.
|
|
It works efficiently across all major desktop and mobile platforms,
|
|
can be extended with lots of <a href="plugins.html">plugins</a>,
|
|
has a beautiful, easy to use and <a title="Leaflet API reference" href="reference.html">well-documented API</a>
|
|
and a simple, readable <a title="Leaflet source code repository on GitHub" href="https://github.com/Leaflet/Leaflet">source code</a> that is a joy to

<div id="map" class="map map-home" style="height: 300px; margin-top: 50px"></div>
|
|
|
|
<p>Here we create a map in the <code>'map'</code> div, add <abbr title="Here we use OpenStreetMap tiles, but Leaflet doesn't force you to — use whatever works for you, it's open source!">tiles of our choice</abbr>, and then add a marker with some text in a popup:</p>
|
|
|
|
<pre class="basic-code javascript"><code>var map = L.map('map').setView([51.505, -0.09], 13);
|
|
