<leaflet-map> 1.0.0 was released on 2015-05-28. Please check out the <a href="https:/leaflet-extras/leaflet-map/releases/tag/v1.0.0">change notes</a> for breaking changes.
</div>
<div id="content">
<p>Most of the options documented in the <a href="http://leafletjs.com/reference.html">Leaflet reference</a> are exported as html attributes. All events are mapped into html events of the same name.</p>
<h2 id="simple">Simple</h2>
<p>Creating a leaflet based map is as simple as adding a <leaflet-map> tag after two lines of boilerplate code to load the web component platform and import the leaflet-map component.</p>
<leaflet-map> </leaflet-map>
<pre class="html"><code>
<<span class="i">script</span> <span class="a">src</span>="<span class="v">../webcomponentsjs/webcomponents-lite.min.js</span>"></<span class="i">script</span>>
<<span class="i">link</span> <span class="a">rel</span>="<span class="v">import</span>" <span class="a">href</span>="<span class="v">leaflet-map.html</span>">
<<span class="i">leaflet-map</span>> </<span class="i">leaflet-map</span>>
</code></pre>
<h2 id="view">Initial View</h2>
<p>Like normal html elements, the map is configurable with attributes. Those attributes correspond to the option parameter of L.map as defined in the <a href="http://leafletjs.com/reference.html">leaflet documentation</a>. For example the initial view is defined as follows:</p>
<leaflet-map latitude="51.505" longitude="-0.09" zoom="13"> </leaflet-map>
<pre class="html"><code>
<<span class="i">leaflet-map</span> <span class="a">latitude</span>="<span class="v">51.505</span>" <span class="a">longitude</span>="<span class="v">-0.09</span>" <span class="a">zoom</span>="<span class="v">13</span>">
</<span class="i">leaflet-map</span>>
</code></pre>
<h2 id="marker">Marker</h2>
<p>Markers can be defined using html tags as well. The following examples creates a semi transparent marker on the left hand side. And a second marker with a popup on click.</p>
<leaflet-map fit-to-markers>
<leaflet-marker latitude="51.5" longitude="-0.10" title="Transparent" opacity="0.6">
</leaflet-marker>
<leaflet-marker latitude="51.5" longitude="-0.09" title="Popup Demo">
<b>Bold</b>
<p>Text</p>
</leaflet-marker>
</leaflet-map>
<pre class="html"><code>
<<span class="i">leaflet-map</span> <span class="a">fit-to-markers</span>>
<<span class="i">leaflet-marker</span> <span class="a">latitude</span>="<span class="v">51.5</span>" <span class="a">longitude</span>="<span class="v">-0.10</span>" <span class="a">title</span>="<span class="v">Transparent</span>"

</<span class="i">leaflet-marker</span>>
</<span class="i">leaflet-map</span>>
</code></pre>
<h2 id="icon">Marker with custom icons</h2>
<p>Markers are based on formating templates called "icons". There are three ways to reference such an icon definition:</p>
<leaflet-map latitude="51.505" longitude="-0.09" zoom="13">
<leaflet-icon id="myicon" icon-url="https://stendhalgame.org/images/mapmarker/me.png"></leaflet-icon>
<leaflet-marker latitude="51.5" longitude="-0.10" title="Icon element reference" icon="myicon">
</leaflet-marker>
<leaflet-marker latitude="51.5" longitude="-0.09" title="Icon json" icon='{"iconUrl": "https://stendhalgame.org/images/mapmarker/dungeon.png"}'>
</leaflet-marker>
<leaflet-marker id="icon-reference" latitude="51.5" longitude="-0.08" title="Icon L.icon()">
</leaflet-marker>
</leaflet-map>
<script>
document.addEventListener("load", function() {
var marker = document.getElementById("icon-reference");
marker.icon = L.icon({
"iconUrl": "https://stendhalgame.org/images/mapmarker/npc.png",
"iconSize": L.point(26, 25),
"iconAnchor": L.point(0, 0)
});
});
</script>
<p>The template icon may be defined using <leaflet-icon> elements. This is the prefered way. Please note that iconSize is mapped to the attributes iconWidth and iconHeight. iconAnchor is mapped to iconAnchorX and iconAnchorY and so on:</p>
<pre class="html"><code>
<<span class="i">leaflet-icon</span> <span class="a">id</span>="<span class="v">myicon</span>"
<span class="a">icon-url</span>="<span class="v">https://stendhalgame.org/images/mapmarker/me.png</span>"> <<span class="i">/leaflet-icon</span>>
<<span class="i">leaflet-marker</span> <span class="a">latitude</span>="<span class="v">51.5</span>" <span class="a">longitude</span>="<span class="v">-0.10</span>" <span class="a">title</span>="<span class="v">Element</span>" <span class="a">icon</span>="<span class="v">myicon</span>">
</<span class="i">leaflet-marker</span>>
</code></pre>
<p>Alternatively plain json is understood, too:</p>
<pre class="html"><code>
<<span class="i">leaflet-marker</span> <span class="a">latitude</span>="<span class="v">51.5</span>" <span class="a">longitude</span>="<span class="v">-0.09</span>" <span class="a">title</span>="<span class="v">Icon json</span>"
<span class="a">icon</span>='<span class="v">{"iconUrl": "https://stendhalgame.org/images/mapmarker/dungeon.png"}</span>'>
</<span class="i">leaflet-marker</span>>
</code></pre>
<p>Last but not least, an instance of L.icon may be assigned:</p>
<pre class="html"><code>
<<span class="i">leaflet-marker</span> <span class="a">id</span>="<span class="v">icon-ref</span>" <span class="a">latitude</span>="<span class="v">51.5</span>" <span class="a">longitude</span>="<span class="v">-0.8</span>" <span class="a">title</span>="<span class="v">L.icon()</span>">
</<span class="i">leaflet-marker</span>>
<<span class="i">script</span>>
document.addEventListener("load", function() {
var marker = document.getElementById("icon-ref");
marker.icon = L.icon({
"iconUrl": "https://stendhalgame.org/images/mapmarker/npc.png",
"iconSize": L.point(26, 25),
"iconAnchor": L.point(0, 0)
});
});
</<span class="i">script</span>>
</code></pre>
<h2 id="vector">Circles, polyline and polygons</h2>
<p>Circles, polylines and polygons can be drawn on the map.</p>

<h2 id="databinding">Data binding and custom components</h2>
<p>Data binding can be used to create markers based on dynamic information, e. g. from the rows of a spreadsheet.
In this example a new component is created which listens for location tracking information and sets a marker accordingly.
A circle is used to indicate the range of uncertainty.</p>
