const cookieParser = require('cookie-parser');

app.use(cookieParser(process.env.COOKIE_SECRET, httponly: true, domain:

Body Parser

Body Parser parses an HTTP request body that usually helps when you need to know more than just the URL being hit. Specifically in the context of a POST, PATCH, or PUT HTTP request where the information you want is contained in the body.

Using body-parser allows you to access req from within routes and use that data.

const bodyParser = require('body-parser');

app.use(bodyParser.json({limit: '50mb'}));
app.use(bodyParser.urlencoded({limit: '50mb', extended: true}));

HTTP Status Codes

HTTP Status Codes indicate whether a specific HTTP request has been successfully completed.

const http = require("http-status-codes");

respondWithItem(res, data){
    return res.status(http.StatusCodes.OK).send(responseFormat(data));
}

Momentjs

Momentjs is a JavaScript date library for parsing, validating, manipulating, and formatting dates.

const  moment = require('moment');

// Add 1 day to current date and format it
moment().add(1, 'day').format("YYYY-MM-DD);
