Requirements to Develop a Web Application Using Java Spring, MySQL, and React.js

 If you want to build a full-stack web application with a Java Spring Boot backend, MySQL database, and React.js frontend, you’re combining some of today’s most popular tools into a powerful modern stack.

Here’s what you need to get started on your Windows 10 (or 11) laptop.

🏗️ Backend: Java Spring Boot + MySQL Requirements

✅ Java Development Kit (JDK)

• Download JDK 17 or later (LTS) from Oracle or Adoptium.

• Make sure java -version works in your terminal or command prompt.

✅ Maven or Gradle

• These are build tools for managing project dependencies.

• Spring Initializr (start.spring.io) helps generate a starter project using either.

• Install Maven (if not bundled with your IDE) and ensure mvn -v works.

✅ Spring Boot

• You don’t “install” Spring Boot globally — you include it in your project using Maven or Gradle.

• Use Spring Initializr to quickly bootstrap your project.

✅ MySQL Database

• Install MySQL Server (community edition) from mysql.com.

• Install MySQL Workbench (optional, for GUI management).

• Ensure mysql command-line tool or Workbench can connect to your database.

✅ IDE

• Use IntelliJ IDEA, Eclipse, or VS Code with Java and Spring extensions.

• IntelliJ IDEA Community Edition works great with Spring Boot.

✅ Postman or REST Client (optional)

• For testing your backend APIs.

🎨 Frontend: React.js Requirements

✅ Node.js and npm

• Download and install from nodejs.org.

• Check with:

node -v

✅ React App

• Use npx create-react-app your-app-name to scaffold a new React project.

✅ Text Editor or IDE

• Many use VS Code for React development, with helpful extensions like ESLint, Prettier, and React snippets.

✅ Axios or Fetch

• To connect your React frontend to the backend API.

✅ npm or Yarn (for package management)

• Comes bundled with Node.js, but some prefer installing Yarn.

🔗 How They Connect

✅ Spring Boot REST API → exposes backend endpoints.
✅ React.js frontend → calls backend APIs (usually via Axios or Fetch).
✅ MySQL database → stores your application’s data, connected to Spring Boot using JPA or JDBC.

🏁 Summary Checklist

✅ Install JDK
✅ Install Maven or Gradle
✅ Install MySQL Server (and Workbench, optional)
✅ Install Node.js and npm
✅ Set up IDEs (IntelliJ, Eclipse, VS Code)
✅ Use Spring Initializr and Create React App to scaffold your projects

With all these in place, you’re ready to start building robust full-stack Java + React applications!
