# Source Mapper
[![Build Status]](https://travis-ci.org/mantoni/source-mapper.js)
[![SemVer]](http://semver.org)
[![License]](https://github.com/mantoni/source-mapper.js/blob/master/LICENSE)
Replace stack traces with original sources using [source-map][]. For node and
the browser.
## Install
```
npm install source-mapper
```
## Usage
```js
var sourceMapper = require('source-mapper');
var extracted = sourceMapper.extract(js);
var throughStream = sourceMapper.stream(extracted.map);
```
## API
- `extract(string)` extracts an inline source map from the given string. The
returned object has the `js` without source maps and a `map` with source
maps.
- `consumer(map)` returns a source map consumer for the given `map`.
- `line(consumer, line[, offset])` maps the given line to the original source
using a consumer. If `offset` is given, it is substracted from the line
number.
- `stream(consumer[, offset])` returns a [through2][] stream that replaces URLs
in stack traces with the original source location using a consumer. If
`offset` is given, it is substracted from the line number.
- `stream(map[, offset])` returns a [through2][] stream that replaces URLs in
stack traces with the original source location using a source map. If
`offset` is given, it is substracted from the line number.
