<p>Node has simple module loading. Here is an example of loading a module:
<pre>
include("mjsunit");
function onLoad () {
assertEquals(1, 2);
}
</pre>
<p>Here the module <code>mjsunit</code> has provided the function
<code>assertEquals()</code>.
<p> The file <code>mjsunit.js</code> must be in the same directory for this
to work. The <code>include()</code> function will take all the exported
objects from the file and put them into the global namespace. Because file
loading does not happen instantaniously, and because Node has a policy of
never blocking, the callback <code>onLoad()</code> is provided to notify the
user when all the exported functions are completely loaded.
<p> To export an object, add to the special object <code>exports</code>.
Let's look at how <code>mjsunit.js</code> does this
<pre>
function fail (expected, found, name_opt) {
// ...
}
function deepEquals (a, b) {
// ...
}
exports.assertEquals = function (expected, found, name_opt) {
if (!deepEquals(found, expected)) {
fail(expected, found, name_opt);
}
};
</pre>
<p> The functions <code>fail</code> and <code>deepEquals</code> are not
exported and remain private to the module.
<p> In addition to <code>include()</code> a module can use
<code>require()</code>. Instead of loading the exported objects into the
global namespace, it will return a namespace object. Again, the members of
the namespace object can only be guarenteed to exist after the
<code>onLoad()</code> callback is made. For example:
<pre>
var mjsunit = require("mjsunit");
function onLoad () {
mjsunit.assertEquals(1, 2);
}
</pre>
</body> </body>
