Usage

1. Pass any object containing into the first argument of ProjectError:

var ProjectError = require('project-error');

throw new ProjectError({
    code: 4010,
    statusCode: 400,
    message: 'Bad Request'
});

2. Pass additional error details as either a string or an array of strings:

var ProjectError = require('project-error');

var errorObj = {
    code: 4010,
    statusCode: 400,
    message: 'Bad Request'
};
var errorDetail = 'This is a one-liner error detail';
throw new ProjectError(errorObj, errorDetail);

var ProjectError = require('project-error');

var errorObj = {
    code: 4010,
    statusCode: 400,
    message: 'Bad Request'
};
var errorDetails = [
    'This is multiple lines of error details',
    'This is multiple lines of error details',
    'This is multiple lines of error details'
];
throw new ProjectError(errorObj, errorDetails);

3. Pass a standard Error object and preserve the stack:

var errorObj = {
    code: 4010,
    statusCode: 400,
    message: 'Bad Request'
};
var errorDetail = 'This is a one-liner error detail';
var error = new Error('Fail!');
throw new ProjectError(errorObj, errorDetail, error);
