documentation

require('callers-module')([frames, origin])

• frames if specified should be an integer bigger than 0 or Infinity.
• origin if specified should be a function.
• if no arguments, the default number of frames is 2 so the origin is the module itself. The stack is sliced by one.

why

You would like to set how many frames are recorded (Error.stackTraceLimit) and from which function the stack should be traced back (Error.captureStackTrace).

By default two frames are recorded, though you can even lower it to one providing a function from which start.

inspirated by

It serves for the same use cases implemented on this cool modules

• visionmedia callsite
• sindresorhus callsites
• sindresorhus caller-path
