How to Manage Session using Node.js and Express

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.

YOUTUBE DEMO DOWNLOAD

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.

Continuous Integration and deployment (CI/CD Pipeline) with Jenkins and Node.js

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 …

HTML5 Push Notification System Using Nodejs MySQL Socket.io

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.

Working with result sets in Connector/Node.js

MySQL 8.0 and the Document Store highlight brand new client tools such as the Shell and Connector/Node.js, both providing a JavaScript implementation of the X DevAPI. Although, for most cases, the public interface tends to be similar on both (barring some small details), there is one notable exception.

The way you handle result sets in a Node.js app using Connector/Node.js is a bit different from the way you do it using an interactive session or a non-interactive JS script in the Shell.

Executing an operation in the MySQL server …
