Sequelize provides a powerful migration system that allows you to carefully manage database  schema changes. Migrations ensure that you can apply specific changes to the  database without risking data loss. Steps to Set Up Migrations: Install Sequelize CLI    npm install --save-dev sequelize-cli Initialize Sequelize CLI: npx sequelize-cli init   These about two commands only will be run once while creating database or when we need to change structure of any table structure once ii is done then for each changes we have to make migration file and have to run it. it may create config.json file in the config/config/json {   "development" : {     "username" : "root" ,     "password" : "Birla@123456" ,     "database" : "mhs" ,     "host" : "82.112.XXX.XX" , // use you server's IP     "dialect" : "mysql" ,     "port" : 3306   },   "test" : {     ...

 =============================================== To collaborate effectively with your friend on the same project, you should use Git branches to manage different lines of development. Here's a step-by-step procedure you can follow to streamline collaboration: 1. Create Separate Branches for Each Developer Create a New Branch for Your Friend: On your local repository, create a new branch for your friend. For example if your friend name is kilvish , if you want to create a branch named kilvish , you would run: make sure you would be on main branch already   command->  git checkout -b kilvish git push origin kilvish 2. Set Up Your Friend’s Environment( On your Friend's System )  at kilvish side  run ->  Clone the Repository (if not already done): If your friend hasn’t cloned the repository yet, they should do so: command ->  git clone https://github.com/Vasu-Birla/your-repo.git   // your your main clone line  Fetch All Bran...

Solution 1: Use Node.js's native import with pm2 You can directly use the native node command with pm2 to run the serve command. Here's how: Install serve as a local dependency if you haven't already: bash npm install serve Start the app using pm2 with node and serve : bash pm2 start "node --no-warnings --experimental-json-modules ./node_modules/.bin/serve" --name "react-app" -- -s build Solution 2: Use a serve script in package.json Another approach is to create a script in your package.json to run serve , and then use pm2 to start that script: Add a script to package.json : ( package.json of frontend folder ) { "scripts" : { "start:serve" : "serve -s build" } } Use pm2 to run the script : pm2 start npm --name "react-app" -- run start:serve Solution 3: Using a custom script with pm2 If you want to avoid npm scripts, you can create a custom Node.js script to run serve using ES Module...

hello friends , am Vasu Birla and Today we will deploy Python App.. in previous post we have deployed NODE js app on 0.0.0.0 (your server IP) and acess it using http://0.0.0.0/   Now  If you want to deploy a Python app separately on the same server, in the /root/demo directory, and access it using http://0.0.0.0/demo,  you can use Apache2 and mod_wsgi to host the Python app.   Additionally, you can configure Apache2 to proxy the requests for the   /demo path to your Python app without affecting the Node.js app hosted at the root.   First of all  put your python project folder on root location of server , using putty with cloning git repo or using FTP server and direct paste folder (in previous post we aleady discussed it)   lets suppose your folder name is demo .. location would be  /root/demo   install necessery things to support your python app .  like pip install or django ..etc     as well install in virtual envi...
