Workaround Auth0 limitations for Netlify deploy previews

[jamesvclements]

Netlify deploys previews of our PRs, at URLs like:

https://deploy-preview-182--bartop-ui.netlify.com/landing

This is sweet. However, Auth0 needs to know about that URL to add it as an Allowed Web Origin.

From their docs:

Please note that the URLs specified for Allowed Web Origins cannot contain wildcards or relative paths after the domain.

So, the auth flow on any deploy previews won't work. I asked in their Gitter:

Hey, the docs state "Please note that the URLs specified for Allowed Web Origins cannot contain wildcards or relative paths after the domain." Is there a workaround for this? We're using Netlify for continous deployment, and they create deploy previews for PRs in the form https://deploy-preview--183-my-app.netlify.com - where the # changes w/ each PR. This means we can't go through the auth flow on any of the deploy previews unless we manually add each deploy preview URL before testing. Thoughts?

We'll see 🤷‍♀️

Hmm, this would be nice to have for sure. If not though, one of the points of dev and staging is to see stuff before it's in production. I feel like this is just like another in between that's nice but not necessary
