documentation
require('v8-callsites')([frames, origin])
frames
if specified should be aninteger
bigger than0
orInfinity
.origin
if specified should be a function.- if no arguments, the default number of
frames
is2
so theorigin
is the module itself. The returned stack is sliced by one.
See also the avaliable methods of the stack trace api like:
getLineNumber
getFileName
getEvalOrigin
- etc.
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
I've been using those a lot.
