Whilst this comment might sound facetious, it isn't intended to be.
The JavaScript ecosystem moves quickly and starter kits are outdated almost immediately as the JS world develops better ways to do things.
At any given month there tends to be a community accepted (to a greater or lesser extent) set of technologies that are the "current best". It would be great to be able to go there and pick up a "January 2016" ReactJS starter kit built around the "current best".
Another related idea is a website listing JavaScript technologies and every month a new poll shows how many people favor one technology over another.
Or a list that allows people to use checkboxes to select the JS technologies, with a grid showing which starter kits use that tech.
