Open Source Resources for Web Application Developers

JS Bin is a webapp specifically designed to help JavaScript and CSS folk test snippets of code, within some context, and debug the code collaboratively.

JS Bin allows you to edit and test JavaScript and HTML. Once you’re happy you can save, and send the URL to a peer for review or help. They can then make further changes saving anew if required.

The original idea spawned from helping developers debugging an Ajax issue. The original aim was to build it using Google’s app engine, but in the end, it was John Resig’s Learning app that inspired Remy Sharp to build the whole solution in JavaScript with liberal dashes of jQuery and a tiny bit of LAMP for the saving process.

punypng is a free tool that dramatically reduces page load times by reducing the file size of an image without any loss of quality. punypng uses several web optimization techniques to reduce the file sizes of your images. It first analyzes the content of your image and figures out the best image format to use.

Depending on the file, punypng will automatically convert your GIF into a PNG format and then further compress that. For JPEGs, sometimes it’s better to make it a PNG, and other times it’s better to keep it as JPEG and use jpeg-tran to optimize it. punypng makes all those decisions for you and ensures the best possible results.

Yesterday, we mentioned How to Delay Images Loading. Today, we have QueryLoader which preloads images or even a whole web page with Loading bar and custom animations.

There is always a minor problem when it comes to preloading image on a website. Nobody really has a full solution for it. There are a lot of preloaders available, but most of the time they only display the words: “Loading page” or have an animated image that spins.

Why can’t there be a nice loading bar of some kind? QueryLoader has it all. Loading bar, custom animations and getting all images included in the web page.

Requirements: jQuery Framework
