``sh`
npm install --save module-parent
`js`
var parentModule = require('module-parent')(module, 0);
var parentName = parentModule && path.basename(parentModule.filename, '.js') || 'app';
Caution: this module clears require.cache to resolve the filename for the parent modules (if numParentsToSkip parameter is set, then require.cache is set for all the module when going up to parent, except last parent).module.parent
By default, points to the module which required this one at first time, not all the modules require'ing it later.module-parent
That means, each time module loads as at first time and, for example, it's not possible to use singleton pattern for all the modules which uses package .
Parameters

var parentModule = require('module-parent')(
moduleToStart, // module to start from
numParentsToSkip // number of parents to skip; default: 0
);
