Once brew is done installing, take note of the Caveats section that is printed to your console. Just like what we did previously for postgres it might be best to create a symlink then two aliases to start and stop the mongo progress.

Basic Authentication with Passport

Basic authentication is one of the simplest authentication strategies because it doesn't require cookies, sessions, or even a login form! Instead, it uses HTTP headers which means credentials are transmitted on each request.

Installation

You will need to install passport and passport-http. The passport-http module is what allows you set up the Basic Authentication Scheme, in addition to a couple other authentication strategies.

$ npm install express passport passport-http --save
