HomeBackend Development
  1. Introduction to Backend Development
  • Understanding the client-server model
  • Role of backend in full-stack applications
  • Overview of Node.js and event-driven architecture
  • Setting up development environment (Node.js, npm, Postman/Insomnia)
  1. Node.js Fundamentals
  • js runtime and non-blocking I/O model
  • Modules (built-in and custom)
  • File system operations and path handling
  • Event emitters and streams
  • Working with npm and package.json
  1. Express.js (Web Framework for Node.js)
  • Setting up an Express server
  • Routing basics (GET, POST, PUT, DELETE requests)
  • Middleware (built-in, third-party, custom)
  • Request and response handling
  • Serving static files
  • Error handling best practices
  • Templating engines (e.g., EJS, Handlebars)
  1. Hono Framework (Lightweight Modern Alternative)
  • Introduction to Hono (edge-friendly and lightweight)
  • Creating a minimal API with Hono
  • Routing and middleware in Hono
  • Differences between Express and Hono
  • Context handling and performance considerations
  1. APIs (Application Programming Interfaces)
  • Fundamentals of REST APIs
  • Designing RESTful endpoints (resources and routes)
  • Request validation and query parameters
  • CRUD operations with databases
  • API versioning strategies
  • Error handling and status codes
  • Introduction to GraphQL (optional advanced topic)
  1. Working with Databases
  • Introduction to databases

  1. Authentication & Security
  • User authentication with sessions and cookies
  • JSON Web Tokens (JWT) and role-based access control
  • OAuth2 and social logins (Google, GitHub, etc.)
  • Password hashing (bcrypt) and secure storage
  • Common security issues: SQL injection, XSS, CSRF
  • Applying HTTPS and securing headers
  1. Advanced Backend Topics
  • Environment variables and configuration (dotenv)
  • Logging and monitoring
  • Rate limiting and API throttling
  • File uploads and handling (Multer, Cloud storage)
  • Background jobs and queues (Bull, Redis)
  • WebSockets for real-time communication
  1. Testing & Debugging
  • Unit testing with Jest or Mocha
  • Integration testing for APIs (Supertest)
  • Debugging using Node Inspector and VS Code DevTools
  • Writing testable, modular backend code
  1. Deployment
  • Preparing backend for production
  • Deployment on platforms Vercel
  • Dockerizing Node.js applications
  • CI/CD pipelines for automated testing and deployment
  • Monitoring and scaling backend services
  1. Project
  • Building a full backend API with Express or Hono
  • Connecting to a real database
  • Adding authentication and authorization
  • Secure deployment to production environment
