Deprecation warnings & discontinued addon support for React 16

[Donaldini]

With the release of React 15.5 as a preparation for React 16 a bunch of deprecation warnings and changes were released.

Some of these are related to Storybook:

Deprecations

• Warning: Accessing PropTypes via the main React package is deprecated. Use the prop-types package from npm instead.

• Warning: A Component: React.createClass is deprecated and will be removed in version 16. Use plain JavaScript classes instead. If you're not yet ready to migrate, create-react-class is available on npm as a drop-in replacement.

Discontinuing support for React Addons

• react-addons-create-fragment

React Test Utils

• react-addons-test-utils

I think this has been dealt with: https://github.com/storybooks/mono/issues/35

The problem is that some of those warnings come from dependencies. One of them, for example, is https://github.com/xyc/react-inspector, which have no activity since the beginning of this year. Maybe some alternative should be considered instead.

Another example is from this organisation: https://github.com/storybooks/react-split-pane/issues/6

React-split-pane has been dealt with, by switching away from the fork to the original.

React-inspector I'll have to look into, do you have an idea what it does and what replacement would be best?

It's used in ActionLogger for displaying actions data in devtools-like way: https://github.com/xyc/react-inspector#objectinspector-

You may consider using redux LogMonitor instead

react-inspector is now forked, updated, published and used in #1008
