> 🔧 Add custom options to Restify's errors!



DEPRECATED!!!



## Install

```

$ npm install --save restify-errors-options

```

## Usage

```js

const errorsOptions = require('restify-errors-options');

// Is extremely important to require restify-errors-options before restify.

const errors = require('restify-errors');

// Default behaviour

const err1 = new errors.NotFoundError({errno: 'NFE'});

console.log(err1.toJSON());

//=> {code: 'NotFound', message: ''}

// Add errno as option to add to the body

errorsOptions.add('errno');

const err2 = new errors.NotFoundError({errno: 'NFE'});

console.log(err2.toJSON());

//=> {code: 'NotFound', message: '', errno: 'NFE'}

console.log(err1.toJSON());

//=> {code: 'NotFound', message: ''}

// Restore the default behaviour

errorsOptions.delete('errno');

const err3 = new errors.NotFoundError({errno: 'NFE'});

console.log(err3.toJSON());

//=> {code: 'NotFound', message: ''}

console.log(err2.toJSON());

//=> {code: 'NotFound', message: '', errno: 'NFE'}

console.log(err1.toJSON());

//=> {code: 'NotFound', message: ''}
