React 16.3.0 made changes with component lifecycles


#1

React decided to change the component lifecycles moving forward. Although the legacy lifecycles will work until React 17, be informed of the changes: deprecating 3 lifecycles and adding 2 new ones


#2

<React.StrictMode> looks useful for preventing problems.

It looks like react-apollo needs to be updated to use static getDerivedStateFromProps() instead of componentWillReceiveProps().
