I&#x27;ve used react-rails as a way to use React components with low friction in rails views. However, its been a few years now since a significant percentage of rails developers have come to look at Rails as an API layer and use SPAs as the UI, regardless of what client-side framework you use.<p>Marketwise, Rails is on a long, slow decline. You should definitely broaden your horizons, even if Rails is going to be around for several years yet. You&#x27;re probably going to see fewer &quot;interesting&quot; Rails projects come up, and a lot more legacy and &quot;mature&quot; applications.  Elixir and Phoenix is where I&#x27;m putting my attention these days, but there&#x27;s a lot of interesting work going on server-side these days as well.
