Must do prop transformation, it needs to add a specific onChange handler to each control.

I dislike this immensly but it'll work with our existing components and is ugly enough to encourage us to move to something like Redux.

// import get from 'lodash/object/get'

const handleControlChange = (onChange, statePath) => (value) =>
  onChange(statePath, value)

Sharing behaviour between React components

React 0.13 introduced using plain Javascript classes to create components, 0.14 introduced "stateless functional components" as another method of defining them. Neither of these have an in-built method for behaviour sharing such as we had with the mixins option passed to createClass. So now we get to review mixins as a pattern for behaviour sharing and, if necessary, come up with something better. If they're not all bad, we'll need to figure out how to, or even if we can, add them to the two new component definition options.

The problem

Dan Abromov's medium article from Mar 2015 makes the case for avoiding mixins.

For me (paraphrasing in the extreme), the key problems exposed are:

mixins can unintentionally hide / distribute the source of behaviour

Rough outline of the steps in an isolated design job

Define project objectives
Review identity standards
Develop concepts and prototypes (The Design process)
Present solution
Evaluate solution (Maybe loops back to Develop)
Prepare for production
Evaluate finished piece(s) (Maybe loops back to Develop)
Deliver finished files for production / distribution
