The best way to do this now is using a module loader like browserify, webpack, or typescript. There are plenty of others as well. Since requires can be made from the relative location of the file, and the added bonus of being able to import templates via transforms or loaders like partialify, you don't even have to use template urls anymore. Just simply inline the Template via a require.

I wrote a post on exactly this subject and spoke on it at our local Angular Meetup. Most of us are now using it in production.
It is quite simple as long as your file structure is represented effectively in your modules. Here is a quick preview of the solution. Full article link follows.
var module = angular.module('myApp.things', []);
var all = angular.module('myApp.things.all', [
'myApp.things',
'things.someThing',
'things.someOtherThing',
'things.someOtherOtherThing',
]);
module.paths = {
root: '/path/to/this/thing/',
partials: '/path/to/this/thing/partials/',
sub: '/path/to/this/thing/sub/',
};
module.constant('THINGS_ROOT', module.paths.root);
module.constant('THINGS_PARTIALS', module.paths.partials);
module.constant('THINGS_SUB', module.paths.sub);
module.config(function(stateHelperProvider, THINGS_PARTIALS) {
stateHelperProvider.setNestedState({
name: 'things',
url: '/things',
templateUrl: THINGS_PARTIALS + 'things.html',
});
});
And then any sub modules or "relative" modules look like this:
var module = angular.module('things.someThing', ['myApp.things']);
var parent = angular.module('myApp.things');
module.paths = {
root: parent.paths.sub + '/someThing/',
sub: parent.paths.sub + '/someThing/sub/',
partials: parent.paths.sub + '/someThing/module/partials/',
};
module.constant('SOMETHING_ROOT', module.paths.root);
module.constant('SOMETHING_PARTIALS', module.paths.partials);
module.constant('SOMETHING_SUB', module.paths.sub);
module.config(function(stateHelperProvider, SOMETHING_PARTIALS) {
stateHelperProvider.setNestedState({
name: 'things.someThing',
url: "/someThing",
templateUrl: SOMETHING_PARTIALS + 'someThing.html',
});
});
Hope this helps!
