ReactComponent.propTypes is undefined when dynamically inject the react build js

Fix this by adding null check.

Thanks! Just to make sure I am understanding what is happening and how to test it ... you are dynamically addicting React after this library is installed?

Looks like I am encountering this as well.
Uncaught TypeError: right-hand side of 'in' should be an object, got undefined
I tried this same approach in #6 but then realized there's some other disconnect here. This solution just masks another problem. I get the same error when I pass in an instance of React.Component or React.FC, with or without props defined. And if I add this undefined check it gets past that and loads the component, but it's not getting props at all.

Oh I see, this package is perhaps assuming we are using propTypes, now https://www.npmjs.com/package/prop-types.
But I am using TypeScript so I have no need for propTypes.

Re-opened #6

Ah, so ReactComponent doesn't always have propTypes. Thanks!

I think I had a similar issue and solved it like this:

window.addEventListener('DOMContentLoaded', (event) => {
  var root = document.getElementById("id")
  var mywc = document.createElement('mywc')
  mywc.settings = "settings"
  root.appendChild(mywc)
}

We adjusted the logic in #50 to allow an alternate prop definition besides propTypes. We cannot current get around the need for a minimal props definition at runtime, however.
