extjs Ext.app.Application for custom package

I am trying to create a package, but it has a bunch of required files and global stores that need to be fetched when the application start. My package used to be part of a larger application, so I had these added to requires: [] and stores: [].

How do we achieve this now that I have a separate package? (Where I no longer have an Application.js file)

Update

I have added a Require.js file that contains all the requires for my package. Now I am left with emulating Application.stores for creating global stores.

Just add dependencies straight to the classes on which they depend (with help requires). In case this store will have to be initialized manually

Answer on update:

Try override constructor of Require class

Ext.define('Require', {
    stores:[],
    constructor: function (config) {
        this.callParent(arguments);
        Ext.Array.each(this.stores, function (storeName) {
            Ext.require(storeName, function () {
                Ext.create('storeName', {});
            })
        })
    }
})
