understack

Translate stacktraces from minified JS to readable format.
This lib relies on source-map (by Mozilla) to find position of given line and column.

Install

`` bash
npm install understack
`

Usage

$3

Suppose your project structure looks like this:

* project/src/foo.js
* project/src/bar.js
* project/build/minified/min.js - result of compiling foo.js and bar.js
* project/build/minified/source_map - source-map for min.js
* project/script.js - here you require understack.js

` javascript
var understack = require('understack');
understack.addSourceMap(__dirname + 'build/minified/source_map', function(err) {
if (err) console.log(err);
});
// . . .
// get error with stacktrace from minified code
var stack = err.stack;
understack.read(stack, function(originStack) {
// do something with original stacktrace
});
``

TODO

* write more examples
* improve error handling
* write some tests
