stack-trace Get v8 stack traces as an array of CallSite objects. Install bash npm install stack-trace Usage The stack-trace module makes it easy for you to capture the current stack: “`javascript import { get } from 'stack-trace'; const trace = get(); expect(trace[0].getFileName()).toBe(__filename); “` However, sometimes you have already popped the stack you are interested in, and all you have left is an Error object. This module can help: “`javascript import { parse } from 'stack-trace'; const err = new Error('something went wrong'); const trace = parse(err); expect(trace[0].getFileName()).toBe(__filename); “` Please note that parsing the Error#stack property is not perfect, only certain properties can be retrieved with it as noted in the API docs below. Long stack traces stack-trace works great with long-stack-traces, when parsing an err.stack that has crossed the event loop boundary, a CallSite object returning '—————————————-' for getFileName() is created. All other methods of the event loop boundary call site return null. API stackTrace.get([belowFn]) Returns an array of CallSite objects, where element 0 is the current call site. When passing a function on the current stack as the belowFn parameter, the returned array will only include CallSite objects below this function. stackTrace.parse(err) Parses the err.stack property of an Error object into an array compatible with those returned by stackTrace.get().
