Before and after package load callbacks about ender HOT 3 CLOSED

huh? You lost me -- could you provide a small code sample of what you're talking about?

from ender.

If I wanted to build a package that keeps track of all of the modules loaded:

(function () {
    var modules = [],
        $ = require('ender');

    // called just before the module is loaded
    $.provide.before = function (moduleName) {
        modules.push(moduleName);
    };

    // callback would have the value of the module's module.exports
    $.provide.after = function (module) {
        // or do something smarter, like getting data from modules
        if (init in module) {
            module.init();
        }
    };

    module.exports = modules;
}());

This is just a simple example. If events were used, this would be even better, since multiple packages could use the events:

(function () {
    var modules = [],
        $ = require('ender');

    $.on('provide', function (moduleName, module) {
        // some distinguishing feature
        if (init in module) {
            modules.push(moduleName);
            module.init(moduleName);
        }
    });

    module.exports = modules;
}());

I can see this being useful for people (like myself) that want to put all of their code in ender, but their code is modular, so they can't depend on all modules being there. Instead of a messy try-catch, they can just use a module db to keep track of modules they're interested in.

This same idea can be used in development to create a test-suite that performs unit tests on modules in a browser environment. This could help automate testing between browsers.

What do you think about it?

Alright -- sorry for taking so long to get back to you!

That makes sense now -- thanks for clearing it up.

I think i would prefer this to live outside the ender-js library. In fact -- i feel like this would be a perfect "plugin" for ender (as a separate package).

Just wrap the original provide and require methods, and make sure you build the plugin into your ender lib first :)

Doing that will give you lots more room to add a proper event system and all that hottness -- stuff we couldn't really get away with adding here. Sound good?

I'm going to close this -- but feel free to reopen if you would like to continue to make it's case to be added to the core of the lib.
