What is are some of Node.js web applications on GitHub that represent PRODUCTION quality Complete applications (not partial demo code) with Authentication, Authorization (Social Logins) and following best practices?

I am in the process of developing a web site with NODE.JS. Instead of re-inventing the wheels , I am planning to take some of the great work done by open source projects and did some investigation . Here are some of good PRODUCTION quality NODE.JS web sites I found . Please give your opinion what would you choose as TEMPLATE as STARTING CODE base so that you can LEVERAGE lots of PLUMBING code .

I may NOT use the functionality of these web site CODECOMAT or NODEBB , but planning to use Lots of common PLUMBING for any project such as Authentication , Authorization , code templates for Application Middleware , ROUTES etc

I am finding CODECOMBAT github code repo is more Well designed and Architected ( other than COffee script makes it look good to eye) than NODEBB . I am not expert at these , I truly VALUE opinion of this hashcode Community experts

If you find any other GITHUB Repos that show ,please let us know your opinion .
