using.js

Simple JavaScript module loader.

Usage

Add your modules to using's paths:

using.modules.dep1 = "dep1.js";
using.modules.dep2 = "dep2.js";
using.modules.dep3 = "dep3.js";

Defining a module with two dependencies:

using("dep1", "dep2").define("dep3", function (dep1, dep2) {
    
    function dep3 () {
        dep1();
        dep2();
    }
    
    return dep3;
    
});

Running some code after loading its dependencies:

using("dep3").run(function (dep3) {
    console.log(dep3());
});

If a module returns an object, its properties can be referenced as dependencies, too:

using().define("data", function () {
    return {
        userName: "user001",
        profile: {
            firstName: "John",
            lastName: "Doe"
        }
    };
});

using("data::userName", "data::profile::lastName").run(function (userName, lastName) {
    console.log(userName, lastName);
});

Loading a file via AJAX as a dependency:

using("ajax:myFile.json").run(function (myFileRequest) {
    console.log(JSON.parse(myFileRequest.responseText));
});
