miniHERE is a smaller version of jHERE: it is a jQuery plugin that wraps the HERE maps API and makes it easy to add maps to websites and programmatically change the zoom level of the map. It has a zoom bar and supports drag and mouse wheel for pan and zoom.
The source code is available on the jhere-resources repository. In there you'll find step by step guidance to building miniHERE with TDD, loading 3rd party dependencies via
$.Deferred and creating a mini-website by taking advantage of the fantastic Docco.
You will need Node.js and npm to install everything that is needed to follow the tutorial. Phantom.JS is optional but nice to have.
