Ruby Survey 2015

Rarebit (creators of Sass and Haml) recently published the 2015 results of their annual Ruby survey, now in its seventh year.

This year saw a significant shift to Ruby 2.2 (40%) following the shift to 2.1 last year (50%). Only about 15% of rubyists remain with Ruby 2.0 or below. JRuby adoption remains below 5%.

Rails remains the dominant web framework (85%) over Sinatra (10%). RSpec still retains 70% preference while many Test::Unit users have switched to Minitest (15%). 60% of rubyists still prefer JQuery, though there has been a 10% shift to other frameworks in the past year. Interestingly the utilization of Javascript remains around the same: 25% use it heavily, 25% rarely and the rest somewhere in-between. Amongst respondents to this survey Node.js utilization has remained around 20% the last couple of years. On the front end CoffeeScript is used more often than not (55%), Haml remains preferred by 45% and Sass by 80%.

For production the preferred web server remains Unicorn (40%) over Passenger (30%) though Puma adoption has reached 15% in its first year now that Rails 4 has better concurrency support.
