Node require analytics

What is this?

A simple library for capturing CommonJS require analytics in Node.js. This is useful for visualizing runtime application dependencies and the times it takes to load them.

How do I use it?

As early as possible in your application, require and start the module analytics gathering like so:

const analytics = require('../dist/util/modules').start();

Then, at the end of your application, you can dump the results to stderr:

analytics.dump();

You can also process the results manually if you prefer, using analytics.report().

By default, no analytics are actually gathered unless you either run the app with the envar REQUIRE_ANALYTICS=true set, or you pass true to start (which allows you to determine your method of enabling or disabling require analytics collection).
