MetroJS API is a tool for integrating interactive Yandex.Metro schemes into a website. Using this API, you can manage schemes and their contents, as well as create various applications. MetroJS is built with Yandex.Maps JavaScript API.
# Clone this repo (or your fork).
git clone https://github.com/metrofun/metro-jsapi.git
# Install all dependencies
npm install
# If you wanna run tests, install also dev dependencies and PhantomJS
npm install --dev
npm install -g phantomjs###Step 1. Enable the API Before using the API features, you must make sure your browser loads all required modules from Yandex.Maps API. Note, metro-jsapi requires Yandex.Maps version 2.1 or higher.

<script src="http://api-maps.yandex.ru/2.1.5/?load=util.extend,util.augment,vow,event.Manager,Map,rojection.Cartesian,collection.Item,Collection,Rectangle,geocode&lang=en-US" type="text/javascript"></script>
<script src="/metro.js" type="text/javascript"></script>

</head>###Step 2. Install "metro-data" All SVG schemes are stored in the dependency package – metro-data. By default images are loaded from "/node_modules/metro-data" path
npm install git://github.com/ymaps/metro-data.git###Step 3. Create a map container Create a nonzero-size visible container where the map will be placed. Any block type of HTML element can be used as the container (for example, the div element with a set height and width). The map will completely fill this element.
<body>
<!-- The container's unique ID (id) will be used in the next step -->
<div id="containter-id" style="width: 500px; height: 400px"></div>
</body>###Step 4. Create a map The map should be created after the web page has completely loaded. This will ensure that the map container has been created and can be accessed by its id. To initialize the map after loading the page, you can use the ready() function.
<script type="text/javascript">
ymaps.ready(function () {
ymaps.createTransportMap('moscow', 'containter-id').then(function (transportMap) {
console.log('map created');
}).done();
);
</script>###ymaps.createTransportMap Static factory method.
Creates a TransportMap instance and returns a Vow promise with it.
