How to handle reducers having child reducers

[simvisfear]

I have been working on chunking, for a big application and have come across a situation where parts of my store have children. (Example shown below)

Store: { holidays: { booking: {}, payment: {}, reprice: {} }, hotels: {}, flights: {}, }

In the above store part, the holidays itself has a combinereducer() that combines child reducers (booking, payment and reprice).

Can you help me on how to do this with chunking explained here? (how to pass them to components when I call asyncRoute() and how to register them).

Thanks in advance
