source: http://toon.io/understanding-passportjs-authentication-flow/

Passport.js is a flexible authentication middleware (allowing users to log in) that can be fully customised and works great with connect/express.

It is flexible in the sense that it allows for different authentication strategies (think via Twitter, via our own user database - installed via separate modules that can be combined) and it allows us to specify any route or output during authentication.

DIFFERENT PARTS IN USING PASSPORT.JS

There are three main parts in using passport.js:

• Requiring the module and using its passport.initialize() and passport.session() middleware with express.
• Configuring passport with at least one Strategy and setting up passport's serializeUser and deserializeUser methods.

Debug node

• if we choose this config we will only need to run the debugger, it will be automatically attached to the app

Attach by Process ID

• when we want to choose this config
• we will need in first place to run the app with --inspect: node --inspect app.js or node --inspect .
• then we will attach the debugger to it by choosing the option with --inspect

Attach to nodemon

• this type of config is great for nodemon, because it help debugger attached to always to the same process via the same port
