Back-End Development with Node.js

In this section

• Introduction to Node.js Back-End Development
  Understand the Node.js runtime, event loop, modules, package ecosystem, and fit for back-end JavaScript services.
• RESTful APIs with Express in Node.js
  Build Express REST APIs with routes, middleware, validation, status codes, errors, and response design.
• Middleware Patterns in Express and Koa
  Compose Express and Koa middleware for routing, validation, authentication, error handling, and reusable request pipelines.
• Asynchronous Patterns in Node.js
  Use callbacks, promises, async/await, streams, and event-loop behavior for non-blocking Node.js I/O.
• MongoDB and PostgreSQL with Node.js
  Connect Node.js services to MongoDB and PostgreSQL with drivers, ORMs, migrations, pooling, and query boundaries.
• Authentication and Session Management in Node.js
  Implement Node.js authentication with sessions, JWTs, OAuth flows, secure cookies, password handling, and revocation paths.
• Node.js Streams for Data Processing
  Process large files and real-time data with Node.js streams, piping, backpressure, transforms, and error handling.
• Error Handling and Logging in Node.js
  Standardize Node.js errors and logs with middleware, structured events, correlation IDs, and operational alerts.
• Scaling and Performance in Node.js
  Scale Node.js services with clustering, load balancing, worker threads, caching, profiling, and resource limits.
• Microservices Architecture with Node.js
  Design Node.js microservices around service boundaries, communication contracts, deployment independence, and operational complexity.
• Real-Time Applications with Socket.io and Node.js
  Build Node.js real-time features with Socket.io, WebSockets, rooms, reconnects, delivery guarantees, and scaling.
• GraphQL Servers with Node.js
  Implement Node.js GraphQL APIs with schemas, resolvers, authorization, batching, caching, and query cost controls.
• Node.js Deployment Strategies
  Deploy Node.js applications with containers, process managers, environment configuration, observability, scaling, and rollback plans.
• Node.js Security Practices
  Secure Node.js services with input validation, auth controls, safe dependencies, headers, secrets, and runtime hardening.
• Node.js Worker Threads and Clustering
  Use Node.js worker threads and clusters for CPU-bound work, process isolation, shared capacity, and scaling limits.
• Serverless Architecture with AWS Lambda and Azure Functions
  Run Node.js workloads on AWS Lambda and Azure Functions with cold starts, event triggers, limits, observability, and cost in mind.
• Event Sourcing and CQRS Patterns in Node.js
  Apply event sourcing and CQRS in Node.js with command models, event logs, projections, consistency, and replay trade-offs.
• Message Brokers for Event-Driven Node.js Architecture
  Integrate Node.js services with RabbitMQ, Kafka, and Redis Pub/Sub using durable messages, retries, and consumer boundaries.
• Node.js Design Patterns for Back-End Development
  Apply Node.js design patterns such as middleware, factory, observer, module, and dependency injection in back-end services.
