gn-map element

The gn-map element provides a wrapper for different map types. If the map-type attribute changes, this change will apply to all child elements. At this time gn-map supports google-map and osm-map, and all children like polygons, points and markers.

Dependencies

Element dependencies are managed via Bower. You can install that via:

npm install -g bower

Then, go ahead and download the element's dependencies:

bower install

Playing With Your Element

If you wish to work on your element in isolation, we recommend that you use Polyserve to keep your element's bower dependencies in line. You can install it via:

npm install -g polyserve

And you can run it via:

polyserve

Once running, you can preview your element at http://localhost:8080/components/seed-element/, where seed-element is the name of the directory containing it.

Properties

• latitude : latitude to center the map on
• longitude : longitude to center the map on
• zoom : The zoom level to be applied to the map
• mapType : The dom-if template decides which type of map is to be included - eg "GoogleMap" or "OpenStreetMap"
• map : Holds the map object and allows to modify values during runtime
• polygons : Array of Polygon objects
• markers : Array of Marker objects
• _userPolygons : Array of user created Polygons
• _userMarkers : Array of user created Markers

Usage Example

<gn-map id="map" class="content fit" 
        latitude="53.694089" 
        longitude="10.608718" 
        zoom="17" 
        map-type="GoogleMap">
  <gn-poly fill-color="red" stroke-color="red" closed>
    <gn-point latitude="53.699089" longitude="10.603718"></gn-point>
    <gn-point latitude="53.694089" longitude="10.608718"></gn-point>
  </gn-poly>
  <gn-marker></gn-marker>
</gn-map>

Testing Your Element

Simply navigate to the /test directory of your element to run its tests. If you are using Polyserve: http://localhost:8080/components/seed-element/test/

web-component-tester

The tests are compatible with web-component-tester. Install it via:

npm install -g web-component-tester

Then, you can run your tests on all of your local browsers via:

wct

WCT Tips

wct -l chrome will only run tests in chrome.

wct -p will keep the browsers alive after test runs (refresh to re-run).

wct test/some-file.html will test only the files you specify.
