    isomerjs

    isomerjs

    Simple isometric graphics library for HTML5 canvas

    Isomer is a lightweight JavaScript library for drawing isometric scenes on an HTML5 canvas. It provides abstractions for points, vectors, paths, shapes, colors, and the complete rendering surface. Built-in shape helpers create prisms, pyramids, and cylinders, while extrusion turns two-dimensional paths into three-dimensional objects. Shapes can be translated, scaled, or rotated around the X, Y, and Z axes. The renderer orders surfaces by depth to reduce visual overlap problems when drawing complex scenes. Developers can combine custom paths and colors to construct buildings, diagrams, game graphics, and procedural illustrations. The library can be added directly through a script file and requires no dedicated 3D rendering engine.

    isomorphic-fetch

    isomorphic-fetch

    Isomorphic WHATWG Fetch API, for Node and Browserify

    Fetch for node and Browserify. Built on top of GitHub's WHATWG Fetch polyfill. For ease-of-maintenance and backward-compatibility reasons, this library will always be a polyfill. As a "safe" alternative, which does not modify the global, consider fetch-ponyfill. The Fetch API is currently not implemented consistently across browsers. This module will enable you to use fetch in your Node code in a cross-browser compliant fashion. The Fetch API is part of the Web platform API defined by the standards bodies WHATWG and W3C. All open source code released by FT Labs is licenced under the MIT licence. Based on the fine work by jxck.

    jQuery Google Maps Store Locator Plugin

    jQuery Google Maps Store Locator Plugin

    A store locator plugin using Google Maps API version 3

    This jQuery plugin takes advantage of Google Maps API version 3 to create an easy to implement store locator. No back-end programming is required, you just need to feed it KML, XML, or JSON data with all the location information. How you create the data file is up to you. I originally created this for a company that didn’t have many locations, so I just used a static XML file. You will need to geocode your locations beforehand or use a geocoding API service if you want to try to do it on the fly. The reason for this is that all free geocoding APIs have strict limits that would easily be exceeded. In the end, you're much better off storing the coordinates versus having to look them up for each location on each request.

    jQuery navobile

    jQuery navobile

    A jQuery plugin that makes mobile navigation easy

    A jQuery plugin that makes mobile navigation easy. Navobile uses CSS to apply CSS3 translations, Mobile device detection, and fix the position of the nav. In the CSS file we used for this demo and the one that is included in the src folder the mobile breakpoint is at 765px using a media query, you can, of course, change this to suit your needs. Changing the timing function used by the transform alters Navobile's css. The available timing functions available are listed on MDN although we don't recommend any of the step timing functions. If you want something really bespoke you could use Lea Vearou's Cubic bezier tool.
