Print a list of all installed node.js modules

in any os

npm -g list

and thats it

list of all globally installed third party modules, write in console:

 npm -g ls

If you are only interested in the packages installed globally without the full TREE then:

npm -g ls --depth=0

or locally (omit -g) :

npm ls --depth=0

Use npm ls (there is even json output)

From the script:

test.js:

function npmls(cb) {
  require('child_process').exec('npm ls --json', function(err, stdout, stderr) {
    if (err) return cb(err)
    cb(null, JSON.parse(stdout));
  });
}
npmls(console.log);

run:

> node test.js
null { name: 'x11', version: '0.0.11' }
