As I’ve previously discussed I want to get node.js running on Android, iOS and WinRT. But to make that happen we need to understand the node.js ecosystem and that includes native add-ons and node-gyp. So I created a node package, node-gyp-counter, to heuristically determine how frequent node-gyp usage is in the node.js world. If my numbers are right then less than 3% of downloads of packages in 12/2014 involved node-gyp in any way. Of that 3%, just 27 packages account for 80% of node-gyp root package downloads. Only 19 of those 27 packages seem relevant to smart phones.
