This is all seems overly complicated.

There's no need to add anything to map, since app, which should be containing everything is already in there. We can just create an array with the subpackages. In my case that was:

var subPackageNames = [
        '+heroes',
        '+heroes/shared',
        '+heroes/hero-list',
        '+heroes/hero-detail',
        '+heroes/hero-dashboard'
    ];

and then modify the provided packIndex function to take a second argument

function packIndex(pkgName, baseName) {
    packages[baseName+pkgName] = { main: 'index.js', defaultExtension: 'js' };
}

now we can add our sub packages to the packages object just like angular does.

ngPackageNames.forEach(name => setPackageConfig(name, '@angular/'));
subPackageNames.forEach(name => packIndex(name, 'app/'));
