Overview

A utility to get the original source code from a source map

What are source maps? http://www.html5rocks.com/en/tutorials/developertools/sourcemaps Why This works well in conjunction with JavaScript error capture. However you will need both line and column numbers. This can be difficult with a simple window.onerror handler as that does not provide the column information. There are various libraries that will wrap native functions with try/catches that could provide the column from error.stack. Use at your own risk (not sure how I feel about them) In my case (enterprise) we have mostly IE8 users at the moment, during window.onerror it is possible to either A. Walk to callee and build a stack or B. Use window.error.errorcharacter to capture the column number. This is what I am going to be doing for the time being.
