this https://github.com/cleverbeagle/pup is the best example of a boilerplate meteor app that i know of at the moment, it seems to meet your requirements and is being actively developed so i’d expect it to maintain a close relationship with the latest meteor and react versions.
Hi, checkout a package I’ve recently published meteoreact:useraccounts (the repo has some examples).
It proides a set of customizable authentication/accounts components which you can just drop into your app (it’s a react alternative to the original useraccounts package).
Also, this post might be helpful if you are planning to use React.
