node.js loads the index.js from top to bottom in order. When it comes to reading this

const passportSetup = require('./config/passport-setup');

Node.js is going to parse this module and will see passport.js loaded and some of passport.js functions in use, but they are not activated. so it will send you an error created by passports. js

first you have to use the cookie session. because cookie session is going to parse the cookie, and retrieve the necessary data which is user.id and pass it to passport.js

server.use(cookieSession({
maxAge:24*60*60*1000,
keys:[keys.session.cookieKey]
}))

then we need to use the

app.use(passport.initialize())

middleware function to initialize passport.js so we can use passport in our route handlers. Middlewares are small functions that can be used to modify incoming requests to our app before they are sent off to route handlers.

then we use

app.use(passport.session())

middleware to connect passport.js to cookie session.
