Mern Stack Tutorial Roadmap

Introduction to MERN Stack

• Overview of MERN: MongoDB, Express.js, React, Node.js
• Benefits of using the MERN stack
• MERN stack architecture
• Setting up the development environment

Building the Frontend with React

• Introduction to MongoDB and NoSQL databases
• MongoDB data model: collections and documents
• CRUD operations in MongoDB
• Indexing, aggregation, and querying data
• Working with MongoDB Atlas (cloud database)

Integrating React with Express.js and Node.js

• Connecting React frontend with Express.js backend
• Handling CORS (Cross-Origin Resource Sharing) issues
• Making HTTP requests from React to Express APIs
• Passing data between the frontend and backend
• Authentication and authorization using JWT (JSON Web Tokens)

User Authentication and Authorization

• Implementing user registration and login
• Password hashing and storing in MongoDB
• Protecting routes with authentication middleware
• Role-based access control (RBAC)
• Session management and cookies

State Management in React

• Introduction to state management libraries: Redux, MobX
• Setting up Redux in a React project
• Redux fundamentals: actions, reducers, store
• Connecting Redux to React components
• Advanced state management with Redux middleware (e.g., Thunk, Saga)

Deployment and DevOps

• Preparing the MERN application for production
• Deploying the backend on cloud platforms (e.g., Heroku, AWS)
• Deploying the frontend on cloud platforms (e.g., Netlify, Vercel)
• Environment variables and configuration management
• Continuous Integration/Continuous Deployment (CI/CD) pipelines

Testing MERN Applications

• Introduction to testing in MERN stack
• Unit testing with Jest and Mocha
• Integration testing with Supertest and Chai
• End-to-end testing with Cypress or Selenium
• Writing test cases for React components and Express routes

Advanced Topics and Optimization

• WebSockets and real-time communication (e.g., Socket.io)
• Implementing GraphQL with MERN stack
• Performance optimization techniques (e.g., lazy loading, code splitting)
• Securing MERN applications (e.g., rate limiting, data validation)
• Scaling MERN applications and microservices architecture
