Short description of what this PR does:

• This PR introduces noRef helpers to workaround react-redux invariant bug: Invariant Violation: You must pass a component to the function returned by connect. Instead received {} due to React.forwardRef

Code Sample

import { withContext } from 'react-context-consumer-hoc'
export default connect()(
	withContext.noRef([ContextA], context => context)(MyComponent)
)

import { withContextAsProps } from 'react-context-consumer-hoc'
export default connect()(
	withContextAsProps.noRef(ContextA)(MyComponent)
)

import { UNSAFE_withContext } from 'react-context-consumer-hoc'
export default connect()(
	UNSAFE_withContext.noRef(ContextA)(MyComponent)
)

How does it work?

It is just a wrapper around the top-most consumer, like this:

withContext.noRef = (ContextAPIs, mapContextToProps) => {
  return ComposedComponent => {
    const Component = withContext(ContextAPIs, mapContextToProps)(ComposedComponent)
    return props => (<Component {...props} />)
  }
}

This fix is temporary and should be removed in v3.

I'm only missing adding the documentation. I want to also add an index to the documentation so that it is easier to follow, it has grown so much in a single day.
