Not here in the UK. Agreed, most Rails jobs are in London but outside the capital PHP:Node is about 7:1 on Indeed.co.uk by job title and that's excluding WordPress, Drupal, Magento and Joomla.
Yeah, PHP, .NET, and Java are always going to be king outside of the tech hubs. I'm saying that the niche that used to be occupied by Rails jobs is being/has been replaced by the niche now occupied by Node.js jobs.
Rails does not have the widespread appeal it used to -- it's not the hip new kid on the block like it was in 2005. At my employer, the people who handle Rails act like it's radioactive and are itching to replace it with more "modern" things.
Node:Rails is about 1.5 in London and 2.2 in the rest of the UK so, yes, Node seems to be more popular than Rails outside the capital. The complicating factor, however, may be the hiring culture in the Rails community. Because Ruby and Rails are so strong on community it may be that a lot more Rails vacancies are advertised informally. That's certainly been my experience.
