Download release

Available on npm

npm install

npm install @flowingcode/google-map

Then import the components you need like:

import '@flowingcode/google-map/google-map.js';
import '@flowingcode/google-map/google-map-marker.js';
import '@flowingcode/google-map/google-map-advanced-marker.js';

Usage

<google-map api-key="YOUR_API_KEY" fit-to-markers>
  <google-map-marker latitude="37.78" longitude="-122.4" draggable="true"></google-map-marker>
</google-map>

Building and running demo

• git clone repository
• npm install
• npm start

The demo will open automatically at http://localhost:8000/demo/. A valid Google Maps API key is required — pass it as a query parameter:

http://localhost:8000/demo/?api-key=YOUR_API_KEY

For polys:

http://localhost:8000/demo/polys.html?api-key=YOUR_API_KEY

For advanced markers:

http://localhost:8000/demo/advanced-markers.html?api-key=YOUR_API_KEY
http://localhost:8000/demo/advanced-markers-clustering.html?api-key=YOUR_API_KEY

Developer Guide

Getting started

<google-map api-key="YOUR_API_KEY" latitude="37.78" longitude="-122.4" zoom="12">
  <google-map-marker latitude="37.78" longitude="-122.4" title="My location"></google-map-marker>
</google-map>

You need a valid Google Maps API key to use these components.

Advanced markers

google.maps.Marker, used by google-map-marker, is deprecated in favor of AdvancedMarkerElement. Use google-map-advanced-marker to use Advanced Markers instead. Both elements can be used on the same map.

Advanced Markers require a Map ID (DEMO_MAP_ID can be used for testing). Note that when a Map ID is set, the styles property of google-map is not applied: the map is styled from the Google Cloud console instead.

<google-map api-key="YOUR_API_KEY" map-id="YOUR_MAP_ID" fit-to-markers>
  <google-map-advanced-marker slot="markers" latitude="37.78" longitude="-122.4" title="My location"
      pin-background="#FBBC04" draggable="true"></google-map-advanced-marker>
</google-map>
