For my project i need google maps api.
I just can serve the api via script tag, so i tried something like that.

my html:

  <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false">    </script>

  {{> hello}}

<template name="hello">
  <div id="map-canvas"/>

my js:

if (Meteor.isClient) {

  var mapOptions = {
      center: new google.maps.LatLng(-34.397, 150.644),
      zoom: 8,
      mapTypeId: google.maps.MapTypeId.ROADMAP

  var map = new google.maps.Map(document.getElementById("map-canvas"),

if (Meteor.isServer) {
  Meteor.startup(function () {
    // code to run on server at startup

On execution the error is:
Uncaught ReferenceError: google is not defined

How can i get this working?
