The Node.js Community continues to grow rapidly. The most common use case for Node.js is certainly back-end development, but there are many examples of cross-platform and desktop apps, even IoT and security apps.
According to Mark Hinkle’s Node.js State of the Union 2017 post (Oct 2017), “Every day there are more than 8.8 million Node instances online, that number has grown by 800,000 in the last nine months alone. Every week there are more than 3 billion downloads of npm packages. The number of Node.js contributors has grown from 1,100 contributors last year to more than 1,500 contributors today. To date there have been a total of 444 releases, and we have 39,672 stars on Github.”
