Migration to React v16

[marians]

The latest react and react-dom module version is 16.2.0.

Upgrading would require some changes:

Replace React.PropType use

See https://reactjs.org/blog/2017/04/07/react-v15.5.0.html#migrating-from-reactproptypes

Replace react-addons-css-transition-group by react-transition-group

Globally replace like this:

-import ReactCSSTransitionGroup from 'react-addons-css-transition-group';
+import ReactCSSTransitionGroup from 'react-transition-group/CSSTransitionGroup';

Replace react-addons-update by immutability-helper

Global replacement:

-import update from 'react-addons-update';
+import update from 'immutability-helper';

react-addons-test-utils gets removed

Now part of react-dom. See https://reactjs.org/docs/test-utils.html

Not sure about the impact or any further changes required.

react-router upgrade

Latest is 4.2.0. It no longer supports scrolling. See below.

react-router-scroll not working

Latest version does not yet work with react-router 4.x.x. See taion/react-router-scroll#52 and https://reacttraining.com/react-router/web/guides/scroll-restoration

We maybe can just delete the applyRouterMiddleware(useScroll()) part from the router in app.js. What are we going to lose?

react-redux upgrade

Maybe the new version 5.0.6 will work...?

react-datepicker upgrade

Maybe 1.0.4 will work?

react-tag-input upgrade

Seems like the latest version 4.7.2 is not compatible with react v16.

I can't find a use for the module anyway.

enzyme upgrade

Maybe 3.3.0 works?

Additional fixes

There might be fixes required in code for other modules.
