Ghost Express Auth Module

Installation

npm install ghost-express-auth --save

Overview

This module is built on top of express and can be imported as a means to handle user authentication in your application. Pass in a configuration file and your DB, and the module defines routes to handle login, registration, password reset and role management.

There are also various exposed middleware objects that can be used for managing user access and permissions.
