Package Exports
- err-code
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (err-code) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme

Create new error instances with a code.
Installation

Why
I find myself doing this repeatedly:
var err = new Error('My message');
err.code = 'ESOMECODE';
throw err;
Usage
Simple usage.
var errcode = require('err-code');
throw errcode('My message', 'ESOMECODE');
Other custom properties
var errcode = require('err-code');
throw errcode('My message', 'ESOMECODE', { some: 'property' });
Fill error object with a code and properties
var errcode = require('err-code');
throw errcode(new Error('My message'), 'ESOMECODE', { some: 'property' });
