If we move away from only spa appications vue has other use cases. For a Rails / PHP site that only needs small amount of javascript vue feels like a natural choice to replace some of the existing jquery

Isn't the same true of React however?

[Can_Not]

It's not the same. VueJS's documentation to add to an existing non-es6 jQuery based project is ahead of react's, and vuejs is a lot smaller.

[jaequery]

no, React will replace your Rails routers.

[jimsmart]

That's not strictly true: vanilla React doesn't even use a router until you wire one up. It's perfectly cromulent to use just few bits of React on an existing web app/site.
