Today, we are going to deploy a very simple web application build using Next.JS framework on Microsoft Azure Web App. This blog is split into two parts - Part 1: covers local web app development and deployment to azure web app using local machine. Part 2: covers deployment using Gitlab CI Prerequisites Before starting, ensure you have the following prerequisites: Azure Account Subscription : If you don't have one, you can sign up for a free account here . Node.js and NPM : Make sure Node.js and NPM are installed on your local machine. Download them here . Git and Azure CLI : Install Git and the Azure CLI. Git can be found here and Azure CLI here . Docker : You’ll need Docker for building and running your Next.js app in a container. Get it here . (It is optional, we can build image directly on azure also) Table of Contents Setup Boilerplate Repo Build Docker Image (optional) Create an Azure Web App Deploy Web App using Azure CLI Step 1: Setup Repository To get started, yo...

In today’s digital landscape, securing data is paramount. Whether you’re building web applications, managing servers, or developing software that handles sensitive information, understanding cryptography is essential. OpenSSL is a powerful toolkit that software engineers can leverage for a variety of cryptographic functions. In this blog, we’ll explore what OpenSSL is, its core functionalities, and how you can effectively use it in your projects. What is OpenSSL? OpenSSL is an open-source implementation of the SSL and TLS protocols. It provides libraries for secure communication and a suite of command-line tools for performing various cryptographic operations, such as encryption, decryption, certificate management, and generating keys. Its versatility makes it a staple for software engineers and system administrators alike. Core Features of OpenSSL Encryption and Decryption : OpenSSL allows you to encrypt and decrypt files and data using various algorithms, includin...

JavaScript is single threaded language.  Synchronous programming is execution of functions in order. Asynchronous programming is executing a long running process outside the main thread. It does not block code execution on main thread. Although it is achieved usually by running asynchronous function on separate thread. Though javascript is a single threaded language it supports aysnchronous behaviour, to understand how we need to understand JS runtime.  

A Makefile is a special file used in Unix and Unix-like operating systems to automate the building and compilation of programs or projects. It contains a set of rules and dependencies that specify how to build a target, typically an executable program or a collection of files. .SILENT : all : first second last # .DEFAULT_GOAL:= last first :     echo "hello world" second :     echo "hello Gaurav" last :     echo "hello world Gaurav"   Refer  here  for more details
