5kb minified + gzipped

bLazy is a lightweight script for lazy loading and multi-serving images, iframes, videos and more (less than 1.4KB minified and gzipped). It’s written in pure JavaScript why it doesn’t depend on 3rd-party libraries such as jQuery. It lets you lazy load and multi-serve your images so you can save bandwidth and server requests. The user will have faster load times and save data usage if he/she doesn't browse the whole page.

It's working in all modern browsers including IE7+.

            super("callback"); // name of the query parameter to use
        }
    }

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public MyAPIResult getStuff(...) {
        ...
    }
}

A year ago, I built a small JS lib using D3.js to visualize JSON-defined genealogy trees.

At the beginning of the year, I added a new feature using flex-calendar and moment-ferie-fr : a birthday calendar using the same JSON genealogy definition and miniature images.

I added this calendar to the …

But on the project I'm working on, we made the choice to use it early on, and we're sticking with it for now. And this …
