Node.js Backend Development

What You Will Learn

• 1 Learn the Node.js runtime architecture, the event loop, and how non-blocking I/O differentiates Node.js from traditional server-side platforms.
• 2 Understand Node.js module systems, the CommonJS and ES Module formats, and how to structure a maintainable project from the ground up.
• 3 Apply core built-in modules including fs, path, http, and stream to handle files, network requests, and data pipelines effectively.
• 4 Build RESTful APIs with Express.js, covering routing, middleware, request validation, and error handling patterns used in production services.
• 5 Implement database integration using both relational databases with an ORM and MongoDB with Mongoose, including schema design and query optimization.
• 6 Develop authentication and authorization systems using JSON Web Tokens, session management, and role-based access control strategies.
• 7 Explore advanced asynchronous patterns including Promises, async/await, event emitters, worker threads, and cluster mode for CPU-intensive workloads.
• 8 Analyze application security practices including input sanitization, rate limiting, HTTPS configuration, and protection against common web vulnerabilities.
• 9 Create automated tests for Node.js applications using unit testing, integration testing, and mocking strategies with modern testing frameworks.
• 10 Deploy Node.js applications using containerization with Docker, environment configuration management, process management with PM2, and CI/CD pipeline fundamentals.
