get ( '/', function ( req, res ) ) // about pageĪpp. set ( 'view engine', 'ejs' ) // use res.render to load up an ejs view file // index pageĪpp. Its an open-source project, with many contributors participating in its development. It provides minimal web app features that make it easier to develop apps and RESTful APIs.

In a production scenario, we should always use a external session store so that sessions are not shared for every user ( Like we did above for the sake of an explanation ).Server.js var express = require ( 'express' ) var app = express ( ) // set the view engine to ejsĪpp. Express Express is a Node.js framework you can use to develop both web and mobile applications. The fourth and the last router is for session destruction. The third router is used for the admin area where the user can only go if he/she is log-in. We are not doing any authentication here for the sake of simplicity. The premise of this challenge is to see the approach you take to: Use an ORM to interact with a simple database model. First, which renders the home page, the second router is used for a login operation. In the code shown above, there are four routers.

The libuv library internally uses another famous library called libeio, which is designed for threading and asynchronous I/O events and libev, which is a high-performance event loop. The libuv library provides the following important core features:

The libuv library creates a thread for the I/O operation (file, DNS, HTTP, and so on) and returns a callback. The libuv library is a cross-platform library that provides an asynchronous I/O facility by enabling an event-driven I/O operation.
