This library parses and extracts function names, URLs, line numbers, and column numbers from the given Error's `stack` as an Array of [StackFrame](http://git.io/stackframe)s. Once you have parsed out StackFrames, you can do much more interesting things. See [stacktrace-gps](http://git.io/stacktrace-gps). Note that in IE9 and earlier, `Error` objects don't have enough information to extract much of anything. In IE 10, `Error`s are given a `stack` once they're `throw`n. ## Browser Support [![Sauce Test Status](https://saucelabs.com/browser-matrix/stacktracejs.svg)](https://saucelabs.com/u/stacktracejs) ## Usage ```js ErrorStackParser.parse(new Error('BOOM')); => [ StackFrame({functionName: 'foo', args: [], fileName: 'path/to/file.js', lineNumber: 35, columnNumber: 79, isNative: false, isEval: false}), StackFrame({functionName: 'Bar', fileName: 'https://cdn.somewherefast.com/utils.min.js', lineNumber: 1, columnNumber: 832, isNative: false, isEval: false, isConstructor: true}), StackFrame(... and so on ...) ] ``` ## Installation ```bash npm install error-stack-parser bower install error-stack-parser https://raw.githubusercontent.com/stacktracejs/error-stack-parser/master/dist/error-stack-parser.min.js ``` ## Contributing Want to be listed as a *Contributor*?
