adding docker-compose for running web-server with postgres & postgres admin console
✳️ Tested both with docker & locally on windows 10

Since the code wouldn't run in my computer (windows 10) I created a docker-compose so I could use this repo.
Eventually I decided to fix all the dependencies so I could run it locally, so I fixed and tested it all the way.

It wasn't an easy one. I encountered some difficult breaking changes and some very unclear indivisible exceptions but in the end I succeeded :)

I learnt a lot by reading your code style, and as many people mentioned it gave me some great notions about how backend development should look like.

I hope this pull request will assist you to fix some major issues that prevent people from using this wonderful repository and I'm here to reply on any questions you have 😃

cool! I ran it locally and finally, it worked. Those outdated dependencies didn't allow me to start this boilerplate locally. But with your pr it worked.
Thanks!

though I had to do a slight change in order to make yarn setup run smoothly.
in
./commands/seed.ts
on line 2

import commander from 'commander'; // < --- NEW works
import * as commander from 'commander'; // < --- OLD fails with errors in console, that .version() is not defined
