lsmod

lsmod fetches the list of modules and the versions loaded by the entry file for your node.js app.

use

var lsmod = require('lsmod');
 
// get an object with module version information
var modules = lsmod();
 
// modules is an object `key:version`
{
    express: '3.0.5',
    hbs: '2.0.1'
}

Note that the version is the actual installed version and not the dependency version string.

install via npm

npm install lsmod
