• Where are good examples of actual code?
  • https://github.com/zeit/now-examples
• How do you get the deployed URL within the code itself? For examle, if you are going to need to generate an OAuth callback.
  • According to this GH issue, the best way is to grab an incoming request header, either x-now-deployment-url to get the unique deployment URL, or the regular host header to get the domain accessed by the client, which might or might not be a custom domain rather than the deployment domain.
