Allows importing a module multiple times without re-registering global services.
Quick Answer
ModuleWithProviders pattern lets a module export providers that are only configured when imported with forRoot(). RouterModule.forRoot(routes) registers the router globally with routes. RouterModule.forChild(routes) doesn't re-provide the router service. Use this pattern for library modules that need to be configured once at root level but imported in multiple feature modules.
