I've moved my site to Netlify
So I’ve been trying to set access to my CMS for a long time now. The problem was that in order to have CMS accessible through my domain, it requires an OAuth server. I’ve figured out that creating a custom serverless function which will handle the authentication with GitHub would be sufficient. So I’ve took some inspiration from the 2 repositories linked in Netlify CMS documentation: The reason because I link both of these was that I’ve used the almighty AWS Amplify CLI to create an API for me, which has bootstrapped an express application for me. This turned out to be way easier then to make 4 independent functions as Amplify is not providing a different way of creating simple shared repository of multiple functions like serverless-framework does.
