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' });
