You successfully caught a wave. This is to be expected in any area of programming. RoR was propelled forward by businesses trying "new" technologies in the hopes that it would pay off in faster / cheaper software development. While RoR is not getting any less useful, the 5 year hype cycle of web dev has made SPAs and Node.js the new technology stack to experiment with. My suggestion is to either secure traditional employment in the RoR stack, or move to the JS and Node.js stack. The former will give you a few extra years, while the latter will allow you to continue with the remote work you have grown accustom too.
