Installation

Usage

Errors in the library can be instantiated directly

var
    LoggableError = require('node-error').LoggableError;
 
throw new LoggableError('message');

or extended using .extend(name, [attributes]):

var
    LoggableError = require('node-error').LoggableError;
 
var
    attributes = function () {
        return {
