React Hooks component under Babel Standalone and pure JavaScript

This is a sandbox for trying out a minimal setup for the following:

• Build a UI library that use React Hooks
  • React Hooks requires a singleton of React in memory
• Consume the library in a few ways:
  • Full Babel: Consume UI library as NPM package
  • Babel Standalone: Consume UI library as CDN bundle, with JSX
  • Pure JavaScript: Consume UI library as CDN bundle, without JSX
• Developers can load a version of React/ReactDOM they want to use to window.React and window.ReactDOM, the UI library must obey
  • UI library include a version of React, which it will fallback to

We are not testing Full Babel in this repository because it is relatively easy to done.

We are testing the following matrix:

• Initialize UI by JSX via Babel Standalone
  • With React loaded
  • Without loading React
• Initialize UI by pure JavaScript, no JSX
  • With React loaded
  • Without loading React
