handling backend process of form data coming from any frontend library, framework, or templating engine

https://www.npmjs.com/package/cookie-parser

npm i cookie-parser

• connect to server → log in → access data → disconnect from server → log in again?

• any requests through backend will automatically use stored frontend data from browser

• server returns cookie to browser (like a code that is attached to each request) and begins session

• requests continue - every time request is made, server references cookie and responds - if cookie is removed session ends

• form data → blob → make readable → send to server

// read json data
app.use(express.json())
// read x-www.form-urlencoded
app.use(express.urlencoded({ extended: true})) 

• dynamic route
