I wish you could also see raw values of those posts, some things I could not draw a conclusion from it.

Example: Rails took a huge percentage hit (-12%), still node.js only got up (+3%), so is web jobs disappearing? or new jobs being created and the market expanding (Machine learning & AI)? Node is going up, React is going up, but Javascript in going down... what gives?

Author here, the Rails drop was a strange one, since it just had a strong June, from 85 postings in June to 59 in July with similar total posting counts in both months. From what I've seen over the years, month to month changes can be hard to explain, so will see if it becomes a trend.

The raw data used for the chart is available in the GitHub repo or in the JS file.

Javascript going down could just be a case that the job posters are assuming for all the JS libraries (node.js/React) that you know JS and not posting it in their Ad.

I don't think that the rails hit, is the result of fewer web jobs. I think it's more a case of the web is transitioning into more JS led architecture.

APIs are even more important for SPAs. It's not like more rich JS front ends obviate the backend.

using node.js, your backend can be JS

I noticed the same trend on StackOverflow careers, it's down about the same percentage comparing to a year ago. Rails is not as exciting anymore. Ruby meetups in my city(Montreal) have less attendants than the new Elixir meetup.
