Inspired by StackOverflow questions on React's new lifecycle methods, I created a light-weight package that visualizes which lifecycle methods are called and in what order. It can be installed with `npm -i react-lifecycle-visualizer`, but was mainly designed to run on StackBlitz:

Version 2.0 has a more consistent interface, includes TypeScript typings, and looks a little prettier. Comments and suggestions are welcome!
