Facebook Login is widely used as an authentication module on websites. Instead of asking user manual details such as email and password and then verify them, it’s better to use already verified user details.

In this article, we are going to learn and implement a Facebook Login System using Nodejs and ExpressJS. You can download the code by clicking the button below.

We all love Ajax, don’t we? And there is an obvious reason. Ajax is great for user experience. In this tutorial, I am going to build an application using Node.js that will let the user upload files using Ajax instead of conventional upload that requires a browser refresh action to see the change.

We have covered session management in ExpressJs using global variable technique which of course will not work in case of shared server or concurrent execution of http requests which is most familiar production scenario.

Codeforgeek readers requested to provide solution for these issue and the optimal one is to use external session storage which is not dependent on application requests, answer is Redis cause this is the light weight and easy to use NoSQL database.

In this tutorial i am going to explain how to design and code session oriented express web applications by using Redis as external session storage.

Session handling in any web application is very important and is a must-have feature, without it, we won’t be able to track user and it’s activity.

In this article, I am going to teach you how to handle Session in Node.js. We will use express as a framework and various other modules such as body-parser to handle form data.

At the time of writing article, the latest version of Express is 4.16.4.

What we are buiding

To demonstrate Session handling in Node, I have developed a basic Log-in and log-out System. In this User can log-in by providing their email, and that email will be used for further Session tracking. Once User log-out, Session will be destroyed and User will be redirected to home page.

Write code, test and deploy

This is one of the common development cycles of any developer.

Most of the time testing and deployment steps do not change frequently and in order to keep the developer focus on writing code, we do the automation of testing and deployment.

This automation is called “continuous integration and deployment” OR CI/CD Pipeline.

In this tutorial, we will learn how to set up continuous integration and deployment (CI/CD) infrastructure for the Node.js project.

Prerequistics

I am going to use Jenkins as the automation tool and Github as source code management system.

Jenkins is free for use but we require public server in order to integrate the Github repository.

For the server, I will be using $5 droplet on Digitalocean. In case you wish to buy it, you …

Real-time web/mobile application is becoming popular day by day. Services like Firebase and Pusher provides API’s and Services to develop effective real-time notification system for your mobile and web apps.

We are not going to use these Services in this post; instead, we will develop an application that pops up notification on a particular event – Say a new comment added on Post. For notification, we will use Chrome desktop notification and for real-time communication – Socket.io.

I have already covered desktop notification here and Socket.io tutorial here.
