Knockout JS – Separate Model from View Model

Knockout JS follows a MVVM approach. In the simple examples the ViewModel seems to hold two kinds of things:

  1. attributes of the Model object
  2. functions operating on the Model – typically via GUI interaction

While this is fine for smaller apps, as apps get bigger there is a growing need to define the Model clearly and separately. After tinkering a bit and some help from Stackoverflow I settled on this scheme. It has worked well for our app.

Define the model separately

AddressModel

Define the ViewModel

AddressViewModel

Define the View
