During 2017 we saw Node.js 6 “Boron” LTS reach maturity. Downloads of the Node.js 4 “Argon” LTS release line (which will remain in maintenance mode through April 2018) trended slightly downward as users upgraded production applications Boron. While the launch of the Node.js 8 “Carbon” LTS release line in October was met with great excitement thanks to much-wanted additions, including things like Async Hooks, an upgrade to V8, and a suite of new features and tools in core.

We’ve analyzed key project metrics for 2017, and discovered that a few of the trends we first saw in 2016 around growth of the core project have been amplified in 2017.
