To implement a basic CRUD (Create, Read, Update, Delete) application in Node.js using Next.js and MongoDB, follow these steps: Step 1: Set up a Next.js project Create a Next.js project (if you haven't already): npx create- next -app @latest nextjs-mongo-crud cd nextjs-mongo-crud Install necessary dependencies: npm install mongoose Step 2: Set up MongoDB connection Create a .env.local file in the root of your project and add your MongoDB connection string: MONGODB_URI= mongodb: //localhost:27017/your-database-name Create a utility file to manage the MongoDB connection. Create a new file lib/mongodb.js : import mongoose from 'mongoose' ; const connectToDatabase = async () => { if (mongoose.connection.readyState >= 1 ) { return ; } await mongoose.connect(process.env.MONGODB_URI, { useNewUrlParser: true , useUnifiedTopology: true , }); }; export default connectToDatabase; Step 3: Create a Mongoose Model Define a model for the data you want...

To create a CRUD application using Spring Boot and Next.js with MongoDB, you'll need to build the backend with Spring Boot to handle the database operations and the frontend with Next.js for the UI. Here's a step-by-step guide to set this up: 1. Set up Spring Boot Backend (Spring Boot + MongoDB) Dependencies (pom.xml) First, add the necessary dependencies to your pom.xml file. < dependencies > <!-- Spring Boot Starter Web --> < dependency > < groupId > org.springframework.boot </ groupId > < artifactId > spring-boot-starter-web </ artifactId > </ dependency > <!-- Spring Boot Starter Data MongoDB --> < dependency > < groupId > org.springframework.boot </ groupId > < artifactId > spring-boot-starter-data-mongodb </ artifactId > </ dependency > <!-- Spring Boot Starter Test (Optional) --> < depend...
