Push a module to a stack before RequireJS is loaded, then when RequireJS get loaded the modules will be invoked.

index.html

<script>
           ministack.push(function ()
           {
              require(['anyMOD'], function(anyMOD){
              
              });

           });
</script>

ministack.js

(function () {
    if (typeof window.ministack !== 'undefined') {
        return window.ministack;
    }

    window.ministack = {
        stack: []
        , push: function (callback) {
            this.stack.push(callback);
        }
        , pop: function () {
            return this.stack.pop();
        }
        , amd: function () {
            if (typeof define !== 'undefined') {
                for (var i in this.stack) {
                    this.stack[i]();
                }
            }
        }
    };
}());

requirejsconfig.js

if (typeof ministack !== 'undefined')
{
    ministack.amd();
