Top 20 JavaScript Technologies: May 2017

May 2017 · 2 minute read

JS Logo In this month’s rankings, React and Vue.js gain, while jQuery and Node.js slip a bit. Note that the increase in AngularJS and the decrease in the AngularJS 2 scores are not indicative of their month to month popularity, but rather, a refinement in the RSIJT scoring algorithm.

Following are the top 10 JS technologies in May 2017, using the RSIJT formula:

RankTechnologyRSIJTUp/Down
1.AngularJS93.7+14.4
2.jQuery61.7-0.6
3.Node.js53.5-3.1
4.React43.3+0.8
5.Bootstrap15.2+0.2
6.TypeScript9.9+0.6
7.AngularJS 27.5-14.5
8.React Native5.8-0.2
9.Backbone.js5.7-0.6
10.Express4.2-0.5

As a bonus, here are the next 10 technologies with their RSIJT score.

RSIJT Methodology

The title of this post is a bit misleading, as this analysis includes CSS libraries, such as bootstrap, LESS, and SASS. I was going to call it “Top 20 Full Stack Technologies” but full stack generally includes technologies such as PHP and .Net. This list only includes HTML/JS/CSS, but it includes those technologies on both the client and server side. To that end, the rating system is called Relative Strength Index of JavaScript Technologies (RSIJT).

To form a list of technologies to look at, I searched GitHub for those libraries with the highest number of stars. I added any libraries that I am aware of that were not included, that might nonetheless be compelling in one way or another. “Technologies” include frameworks, libraries, languages (like ES6 and TypeScript), task runners, testing libs, UI libs, and anything else in our JS world.

The RSIJT formula factors in discussions on Stack Overflow, and job postings on Dice. It weighs two types of job postings – those which contain the technology in its title are given more weight, and those which contain the technology in its description are given a lesser weight.

To make the list relevant, the ratings are computed based on the last month’s worth of data.

The technologies included in this analysis include:

AMD, angular2, angularJS, babel, backbone, bootstrap, bower, chart.js, coffeescript, common.js, d3, ember.js, es6, express.js, flux, foundation, grunt, gulp, handlebars, impress.js, jasmine, jquery, karma, leaflet, less, lodash, meteor, mocha, modernizr, moment.js, mustache, node, polymer, react-native, React.js, redux, require.js, reveal.js, sails, sass, semanticUI, socket.io, three.js, typescript, underscore, vue.js, web components

Over time I will be revising the list and formula. If you have any suggestions on how to make this more accurate or useful, or if you know of other JS tech that should be included in the analysis, please drop me a line!
