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());
