gmaps.core

gmaps.js core that contains the base for create simple maps using Google Maps API

gmaps.core

Contains the base for create simple maps using Google Maps API. It serves as base for other gmaps.js modules.

Install

For using with bundlers (as Browserify or Webpack):

npm install gmaps.core --save

For using directly in the browser, download the gmaps.core.js (or gmaps.core.min.js) in dist.

Usage

You need to register a <script> tag with the Google Maps JavaScript API, then import gmaps.core.

Every Google Maps map needs a container (<div id="map"></div> in this demo), which needs to have width and height, and be visible (without display: none, for example):

<!DOCTYPE html>
<html>
<head>
  <title>Test</title>
  <script src="http://maps.google.com/maps/api/js?sensor=true"></script> 
  <script src="gmaps.core.js"></script> 
  <style type="text/css">
    #map {
      width: 400px;
      height: 400px;
    }
  </style> 
</head>
<body>
  <div id="map"></div>
  <script>
    var map = new GMaps({
      el : '#map',
      lat: -12.0433,
      lng: -77.0283,
      zoom: 12
    });
  </script> 
</body>
</html>

For more examples you can check the tests in this repo.

Documentation

Constructor / initialize: new GMaps(options)

Create a new instance of GMaps, a wrapper for simpler use of the Google Maps JavaScript API. The new instance has the same methods of google.maps.Map.

GMaps accepts all the MapOptions and events listed in the Google Maps API.

fitZoom()

Adjust the map zoom to include all the markers added in the map.

fitLatLngBounds(latLngs)

Adjust the map zoom to include all the coordinates in the latLngs array. latLngs must be an array of google.maps.LatLng objects.

setCenter(lat, lng, callback)

Center the map using the lat and lng coordinates. If a callback if passed, it triggers after the center.

getElement()

Return the HTML element container of the map.

zoomIn()

Increase the map's zoom in 1 point.

zoomOut()

Decrease the map's zoom in 1 point.

refresh()

Trigger a resize event, useful if you need to repaint the current map (for changes in the viewport or display / hide actions).

GMaps.arrayToLatLng(coords, useGeoJSON)

Return an array of google.maps.LatLng objects. If useGeoJSON is true, inverts the order of coords before convert it, since GeoJSON format has the order longitude, latitude instead Google Maps' latitude, longitude. Supports simple or multi-dimensional arrays.

GMaps.coordsToLatLngs(coords, useGeoJSON)

Return a google.maps.LatLng object from a two-elements array. If useGeoJSON is true, inverts the order of coords before convert it, since GeoJSON format has the order longitude, latitude instead Google Maps' latitude, longitude.
