expressJwt needs specified algorithm

[aslak01]

Hey,

I had to modify auth.service.js to get this to run, adding algorithms: ['RS256'] to the expressJwt configuration.

There are also quite verbose warnings popping up at npm run dev complaining about mongodb settings (but that is probably because I updated it before running since npm informed me that the original mongo version included had severe security problems.

The useMongoClient option is no longer necessary in mongoose 5.x, please remove it.

I think this project seems quite helpful to someone learning about node backend stuff (like me) so I figured I'd comment about it.

Hi @aslak01 I am very happy to know that the project has been useful to you. What do you think if you send a PR with the changes you made and so we help more people who start with nodejs?
