## README

# express-error-with-sources [![Build Status](https://travis-ci.org/floatdrop/express-error-with-sources.png?branch=master)](https://travis-ci.org/floatdrop/express-error-with-sources)

Enhanced express 3 error handler which inserts source code within error stack for
JavaScript.

__Deprecated: use [express-stackman](https://github.com/floatdrop/express-stackman) instead__

## Usage

Install module:

`npm i express-error-with-sources --save`

Insert middleware into your express app:

```javascript

// Be sure to add it after `.get`, `.post` and ohters routers - otherwise error will be not intercepted

app.configure('development', function() {
  app.use(require('express-error-with-sources')({contextSize: 3}));
});
```

## Options

 * `contextSize` - Number of lines to insert before and after the error line (default: `3`)
 * `title` - Title of html error page (default: `Error`)
 * `depth` - How deep `util.inspect` should go (default: `5`)

## Html output 

You can see instant example by doing this:

```bash
git clone https://github.com/floatdrop/node-parsetrace && cd $_
npm i && node example
```

Open [`http://localhost:3000`](http://localhost:3000) for exception example or [`http://localhost:3000/object`](http://localhost:3000/object) for object example.

On [`http://localhost:3000`](http://localhost:3000) you should see something like that:
