Readme

Source
caller

Figure out your caller (thanks to @substack).

Initialization Time Caller
// foo.js

var bar = require('bar');
// bar.js

var caller = require('caller');
console.log(caller()); // `/path/to/foo.js`
Runtime Caller
// foo.js

var bar = require('bar');
bar.doWork();
// bar.js

var caller = require('caller');

exports.doWork = function () {
    console.log(caller());  // `/path/to/foo.js`
};

Depth

Caller also accepts a depth argument for tracing back further (defaults to 1).

// foo.js

var bar = require('bar');
bar.doWork();
// bar.js

var baz = require('baz');

exports.doWork = function () {
    baz.doWork();
};
// baz.js

var caller = require('caller');

exports.doWork = function () {
    console.log(caller(2));  // `/path/to/foo.js`
};
