Open Source Resources for Web Application Developers

With more and more users browsing the web with a mobile device, it’s time to begin with mobile web development. In this tutorial we are going to develop a simple Mobile Image Gallery using the amazing jQTouch jQuery plugin for mobile web development. jQTouch is a jQuery plugin with native animations, automatic navigation, and themes for mobile WebKit browsers like iPhone, iPod Touch, G1, and Pre.

Mobile Image Gallery is going to show some albums in a list view which will reveal a wall of thumbnails once it’s clicked. When a thumbnail is clicked, we get to the full image view where we can navigate through all the photos by either clicking on the navigation buttons or swiping over the image.

SpryMap is a super lightweight (2.8 KB), dependency free Javascript widget that turns any HTML element into a Google Maps-like click and drag window. SpryMap is released under the creative commons license, essentially you’re free to use it and adapt it for any personal or commercial purposes.

When using this script, you are given full control over how you want the map to act. What coordinates do you want it to start at? Do you want it to animate to a stop, or stop immediately when the user releases the mouse? Do you want the dragging to stop when an edge is hit? Would you like soup or salad with that? SpryMap aims to give you full control over how it acts.

Requirements: Javascript Enabled

The Lumebox is an Open-Source Lightbox clone written as a JavaScript jQuery plugin with a few added features. One of the main features is that it can parse RSS feeds just as easily as displaying images.

The Lumebox also searches the post or page for links leading to images (and RSS-feeds) and opens them in a popup instead of following them. The Lumebox was written using jQuery 1.4.3. The Lumebox plugin is released under the GNU GPL.

Patrick Wied has shown us how to generates a real-time heatmap with javascript and the HTMLCanvas element depending on the user’s mouse movement.

It is also possible to save the image data of the heatmap. You just have to use the getData function, which returns a (long) data-URL of your heatmap image, to get it. This is especially useful for subsequent serverside processing or saving the image on the client.
