# last-error-middleware

  Middleware for catching the last `express.js` error and rendering it as json or an error page.

## Installation

    $ npm install last-error-middleware

## Example

```js

var lastError = require('last-error-middleware');

app.use(lastError({ pages: {

  '401': 'path/to/401.html',

  '404': 'path/to/404.html',

  '500': 'path/to/500.html',

  '503': 'path/to/503.html',

  '*'  : 'path/to/omg.html',

}));

```

## API

### .LastError(options)

  

  Construct a `last-error` middleware generator with custom `options`. The defaults are:

```js

{

  "pages": {},     // status code to html template path

  "stack": false   // return the error stack with json responses

}

```

### on('err', ..)

  Emitted on every error.

```js

var lastError = require('last-error-middleware');

var errors = lastError({ pages: {

  '401': 'path/to/401.html',

  '404': 'path/to/404.html',

  '500': 'path/to/500.html',

  '503': 'path/to/503.html'

});

app.use(errors);

errors.on('err', function (err) {

  console.log(err.stack);

});

```
