require-lazy

A RequireJS plugin for lazy loading AMD modules packaged with r.js, automatically splitting packaged code in bundles, cache-breaking the bundles only when the code changes, and defining module metadata and module discovery in Javascript applications.

Quick Example

Main module (main.js):

define(["lazy!modules/m1", "lazy!modules/m2", "lazy!text!templates/faq.html"],
function(m1, m2, faq) {
	...
});

In the simplest case where the modules main, m1, m2 have no common dependencies, Require-Lazy build scripts will create 4 separate bundles. One will contain main.js and lazy.js, one m1.js and all its dependencies, one m2.js and all its dependencies and one text.js and faq.html.

The URL for each module will look like:

/scripts/app/m1-built.js?v=684beaf379a164c2d4044a74f22ffc6d

The v request parameter is a hash of the contents of the built file, used as cache-breaker.

The lazy plugin will replace each lazy module with a lazy stub. The stub has (for the time) one method, get() that returns a promise for the real module:

m1.get().done(function(m) {
	// here m is the real module
});

A more detailed discussion and an example project setup can be found in the examples/simple directory.

Development Status

This project is an idea under development. While many things work, it is expected that many more will not. Even worse, some things may not work as expected. Moreover the code is not thoroughly tested yet.

However, I am quite satisfied with how things work at the moment; I do not expect any radical API/usage changes. This means that this project can be considered fairly stable API/usage-wise.

Ideas, critisism, comments, code contributions are all welcome!
