Goal: Reduce dev - feedback cycle by using App Engine dev server. For my use this must be available as a public HTTPS address. App Engine dev server only supports HTTP.
In case you've got only one module you need to reach out via SSL, you can simply use this one https://github.com/cameronhunter/local-ssl-proxy. Installation and usage are super easy. Just change the target port to your module port and then browse it via https to the source port. If you need to reach to multiple modules, you need to run it multiple times with different params (ports).
