Q-REQUIRE
Asynchronous CommonJS require module loader for Node and browsers.
The browser implementation is good for development where the
JavaScript is hosted on the same domain of origin as the page, for
live debugging. For production, it is generally preferable to build
a module transport bundle and to put it on a CDN.
Implements:
* http://wiki.commonjs.org/wiki/Modules/1.1.1
* http://wiki.commonjs.org/wiki/Modules/Async/A
Node:
$ npm install q-require
var REQUIRE = require("q-require/require");
var LOADER = require("q-require/loader");
// construct a require()
var loader = LOADER.Loader({"paths": [__dirname + "/examples/package/"]});
var require2 = REQUIRE.Require({"loader": loader});
// load the main module, asynchronously
var promise = require2.exec("main");
var Q = require("q");
var SYS = require("sys");
Q.when(promise, function (main) {
// ok
SYS.puts(main);
}, function (reason) {
// error
SYS.puts(SYS.inspect(reason));
});
Browser:
<script src="require.min.js"></script>
<script>
require = Require("path/to/js");
// async require a main module
require.exec("main");
// or
require.ensure(["foo", "bar", "baz"], function (require) {
var FOO = require("foo");
var BAR = require("bar");
var BAZ = require("baz");
});
</script>
This asynchronous loader uses a simple heuristic for analyzing
dependencies; it reads all require calls with string literals.
You'll need to trick the regular expression if you have require
calls that do not imply static dependency, like require((id)).
If you have a dynamic dependency, use require.ensure or
require.exec to asynchronously advance require to include
additional modules and their transitive dependencies.
require.min.js includes ECMAScript 5 shims, so more Object, Array,
String, and Date functions are guaranteed to work. It also
bootstraps require with the following modules:
* q
* require/http
* require/q-http
* require/module
* require/loader
* require/require
