Where can I find MERN stack boilerplates?

I’m quite comfortable with react now and I want to start making full stack web apps, but I’m not sure how to get started. I finished the course “Node with React” by stephen grider and we made a project that uses mern stack with google auth. Are there any boilerplates that use that? The most complicated part of the course was setting up user auth with google plus and somehow getting it to work with react.
