Dov B. Katz explained to us:
It provides a methodology for organizing JS libraries, and programmatically loading them by simply “asking” for them. Example code: JSLoader.load(“ria”,”ext”,”2.0-beta1”);
I developed it as a mechanism to provide hosted Ajax libraries within a large enterprise (zero install, we maintain the latest releases) and it has been very successful. Furthermore, because no install is needed, I have leveraged TWiki to create a rapid prototyping environment, which has led to widespread adoption in the enterprise.
Ultimately, it’s just dynamically writing
linktags onto the page… Not rocket science, but it works well, and it’s proven its value in an enterprise environment.
- First of all, it’s a zero-install solution. The goal is to eventually deploy this style of loading and file organization on a “hosted toolkit” system and allow websites to leverage the distribution of new toolkits without having to figure out how to install them.
- Second, because multiple sites will share this code the browser and proxy caches will help make things more efficent
- Finally, the maintainability of toolkits is minimized as content needs to be distributed only once, instead of having each user download a private copy
How do I get started?
// First Load the Script <script src="http://vps.jsloader.com/assets/jsloader.js"> // In one script block JSLoader.load("ria","prototype","1.5.1"); JSLoader.load("ria","prettify","1.0"); // In another script block: Event.observe(window,"load",prettyPrint); // JSLoader takes care of the rest! // Prettify will take any <pre class="'prettyprint'"> // and color-code them.
