How i can use this package in my express project?

First, install package into your project

npm i express-parsers

After installing import intro your code

const ExpressParsers = require('express-parsers');

After importing you must configure with your express

const express = require('express');
const parsers = new ExpressParsers(express);

After that you can use your project with like that:

// Parse cookies
app.use(parsers.Cookie);
// Saves cookies to res.locals.cookie

// Parse POST request body
// If you has some configration with Express.json you can add that with like that
parsers.Body = {
    /* Some magic here too */
}
app.user(parsers.Body)

// Parse GET request url data parser
// If you has some configration with Express.urlencoded you can add that with like that
parsers.URL = {
    extended: true
    /* Some magic here too */
}
app.use(parser.URL);
