Hi thanks for this library. It looks great all though I've had some problems getting off the starting block with it.

I've prepared an example project which I believe should work but while parsing a stack trace from an exception it throws an error.

Expected Behavior

No exception should be thrown while parsing the stack trace in the example project.

Current Behavior

The following exception is thrown while parsing the stack trace in the example project:

C:\projects\github\stack-trace-test\node_modules\error-stack-parser\error-stack-parser.js:31                                      
                return this.parseV8OrIE(error);                                                                                   
                            ^

Steps to Reproduce (for bugs)

I've prepared an example repository:
https://github.com/ashleydavis/stack-trace-test

Clone the repo. Or download and unpack the repo.
Use npm install to install dependencies.
Use npm start to run the example project.

The exception mentioned above is thrown.

Context

I was hoping to use your stack trace parser in my project, but I've been blocked from using it by some basic problems. This is just the first issue, if we can solve this one I'll prepare an example that demonstrates the next problem.

Your Environment

  • stacktrace.js version: 2.0.2
  • Browser Name and version: Node.js v8.9.4
  • Operating System and version (desktop or mobile): Windows 10
  • Link to your project: https://github.com/ashleydavis/stack-trace-test

Possible Solution

Sorry, no idea.

    I have a work around to this problem.

    Code like this doesn't work:

    const { parse } = require('error-stack-parser');

...

const frames = parse(error);

    This code does work:

    const errorStackParser = require('error-stack-parser');

...

const frames = errorStackParser.parse(error);

    This is no longer a crucial problem for me, but would be nice if it would work because that's a common coding idiom in JavaScript.

    What also works is following:

    import errorStackParser from 'error-stack-parser'

const frames = errorStackParser.parse(error);

    I think the problem is that if one invokes parse without the outer scope/object, this will be undefined in https://github.com/stacktracejs/error-stack-parser/blob/master/error-stack-parser.js#L27
