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' });
