Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including node-gyp-counter with all npm packages installed. Try it out:

var nodeGypCounter = require("node-gyp-counter")

node-gyp-counter v0.0.3

Collects statistics on node-gyp usage from NPM


An unscientific exploration of how node-gyp is being used in the node.js ecosystem.

How to install

NPM is your friend:

$ npm install node-gyp-counter

Although generally one suspects package.json is preferable.

How to use

Take a look at tests/tests.js for an example. There are really just two key functions and they are in index.js.

var nodeGypCounter = require("node-gyp-counter");
var npmUtilities = require("node-gyp-counter/lib/npmUtilities");

nodeGypCounter.downloadAndDisplayData("localNpmDBName", "npmStatCache", npmUtilities.skimDbUrl);

This will output to the console a few statistics about node-gyp usage in NPM. You can also call downloadGenerateIndexAndAnalyze with the same arguments and get back a JSON object with the raw data.


The code doesn't seem very friendly, it eats up the main thread!

This code was really written as a canned query not as anything that would be run on an actual production server. I just load it up on my local node.js instance and run. So I have spent no time worrying about making it friendly to any code it shares the node.js server with.

How correct is the code?

You may have noticed that there is literally no testing, at all, anywhere. Who knows what horrific programming errors I have committed?

But wait, it gets worse! You see I didn't have a fully reliable way to figure out which packages use node-gyp. So I built a heuristic instead. The reason is that to be really sure which packages use node-gyp I would have to download and install, well, all packages. That turns out to involve terabytes of downloads and um... no. So instead I look for things like install scripts or gyp flags. Again, not terribly scientific.

How correct is the analysis?

Oy... where to begin? I decided for no good reason to only look at the latest versions of projects. So if a project did use node-gyp and doesn't anymore I'll miss it. I only use the previous month's data for download stats. So a project that hasn't had a recent release and so doesn't have a lot of updates could easily be undercounted. I allow in projects with broken dependencies for no good reason at all (presumably their downloads are low since they shouldn't work). Etc.

How long should it take to download all the data?

A long, long time. PouchDB seems pretty glacial. It took me 54 minutes to download the NPM package database. By comparison CouchDB synch'd the same data in 20 minutes. I hope to eventually track down and fix these problems (I have suspicions about what the problem is) but in the meantime, patience is a virtue.

How do I run tests?

What tests? O.k. there is one test. I just use that because Mocha is easy to run in Intellij. But really, there are no tests.

Why do you use the URL rather than

In theory iriscouch is faster, especially because it doesn't use HTTPS. But in practice I've had endless problems with node.js timing out trying to connect to iriscouch. Iriscouch does appear to be up and working but in examining connection times it does take quite a while to establish a connection. I think this time exceeds node.js's patience and I have not found a way to configure node.js's behavior. Note that the timeout option on things like request is about how long to wait for data, not for the TCP handshake.
