Description

Support react and react-dom 16.11.

References

#96

Testing

I tested by changing these lines
https://github.com/auth0/auth0-react/blob/master/package.json#L75-L76
to

    "react": "~16.11.0",
    "react-dom": "~16.11.0",

and running npm test (these all pass)

I reverted this because I figured it's better to test with 16.13 normally. Is there a different approach you'd like to take?

I tried setting up the integration tests but I ran into these kinds of errors:

Module not found: Can't resolve '@auth0/auth0-react' in ' ...

@adamjmcgrath how long does ci/circleci build take?

@tiagob I imagine forked PRs are not set up to run on the CI. cc @adamjmcgrath

@adamjmcgrath I'm using this in a full stack developer tool I made. It generates the boilerplate for a full-stack. It includes Auth0 with RN/Expo and React web. I'd love to hear any advice or feedback you could provide
