Ponyfill for Error#captureStackTrace

This is useful for creating cross-platform code as Error#captureStackTrace is only available in V8-based JavaScript environments like Node.js and Chrome.

Install

npm install capture-stack-trace

Usage

import captureStackTrace from 'capture-stack-trace';

const object = {};
captureStackTrace(object);
object.stack;  // Similar to `new Error().stack`

API

captureStackTrace(object)

Creates a .stack property on the given object, which when accessed returns a string representing the location in the code at which captureStackTrace() was called.

Note: This ponyfill does not support the second parameter of Error#captureStackTrace.

capture-stack-trace's Issues

Missing License file in npm package

Hello, is it possible to incorporate the LICENSE file inside the npm package ? Now it's missing. It's implied by MIT license that if licensed under the MIT the source code must be accompanied by full license text. If the license file is not in the npm package a lot of people cannot use it.

Thank you

Yarn failed because the hash didn't match

Hello, I found that the hash was changed but the version was not recently. So I should change the hash myself.

support `at` param

Error.captureStackTrace() supports an second param at/fn/subject

function a(fn) {
  const o = {}
  console.log(Error.captureStackTrace(o, fn))
}
function b(fn = a) { a(fn) }

function c() {
  // yields:
  // at b (...)
  // at c (...)
  b()

  // yields:
  // at c (...)
  b(b)
}

It would be great if capture-stack-trace would support that too.
