Preact, a lightweight alternative to React, also has seen growth and could become a force in the future.
On the down side, Backbone, which accounted for almost 0.1 percent of all downloads in 2013, now comprises only about 0.005 percent of downloads (about 750,000 per month). Backbone has declined steeply but is kept afloat by the long shelf life of projects using it, NPM reasoned.
Another framework, Vue, is growing much faster than both Angular and the Ember framework, although it has thus far ascended to just about 0.01 percent of downloads.
NPM ranked frameworks based on their rate of growth in 2016 and 2017, rather than total download numbers:
Express still rules at the back end

Despite commanding the back end, Express accounted for 1.5 percent of total downloads in 2013 but just about 0.1 percent now.
