err-code

Create new error instances with a code and additional properties.

# Installation

`$ npm install err-code` - `NPM`
`$ bower install err-code` - `bower`

The browser file is named index.umd.js which supports CommonJS, AMD and globals (errCode).

# Why

I find myself doing this repeatedly:

var err = new Error('My message');
err.code = 'SOMECODE';
err.detail = 'Additional information about the error';
throw err;

# Usage

Simple usage.

var errcode = require('err-code');
// fill error with message + code
throw errcode(new Error('My message'), 'ESOMECODE');
// fill error with message + code + props
throw errcode(new Error('My message'), 'ESOMECODE', { detail: 'Additional information about the error' });
// fill error with message + props
throw errcode(new Error('My message'), { detail: 'Additional information about the error' });
// You may also pass a string in the first argument and an error will be automatically created
// for you, though the stack trace will contain err-code in it.
// create error with message + code
throw errcode('My message', 'ESOMECODE');
// create error with message + code + props
throw errcode('My message', 'ESOMECODE', { detail: 'Additional information about the error' });
// create error with message + props
throw errcode('My message', { detail: 'Additional information about the error' });
