dependency-ls
This module returns a promise containing an object of top level node modules installed in the supplied path.
This module is essentially a fork of https://www.npmjs.com/package/npmlist. I just needed the results in a json object and I wanted the module to be requireable.
USAGE
npm instal dependency-ls --save
var depls = require('dependency-ls')
return depls(process.cwd())
.then(function(result) {
console.log(result)
}
