Node.js: Server-Side JavaScript for Production Backends
Node.js runs JavaScript on the server using a non-blocking, event-driven architecture that handles thousands of concurrent connections without threading overhead. It is the runtime behind REST APIs, real-time services, microservices, and serverless functions at companies of every size. This track covers the full stack of server-side Node.js — from spinning up your first Express route to designing resilient, observable, distributed systems in production.
What You Will Learn
You will build RESTful APIs with Express.js, persist data with MongoDB and Mongoose, and secure applications with authentication and authorization patterns. From there the track moves into Worker Threads for CPU-bound work, Streams and Backpressure, Redis caching patterns, and message queues with RabbitMQ. Advanced topics include real-time communication with WebSockets, gRPC microservices with Protocol Buffers, GraphQL APIs, Event Sourcing and CQRS, distributed tracing and structured logging, and V8 memory profiling — plus production resilience patterns such as circuit breakers, retries, and graceful shutdown.
The Learning Path
Twenty-two courses span A1 through C2. The path opens with environment setup and a first REST API, progresses through B1 topics like TypeScript tooling and data persistence, then deepens at B2 with testing, debugging, streams, worker threads, and event-driven architecture with RabbitMQ and Redis. The C1 tier covers real-time communication, deployment and scalability, microservices and API gateway design, performance optimization, security best practices, and observability. The track finishes at C2 with serverless functions, GraphQL, advanced memory management, and production resilience — the hardest operational concerns you will face running Node.js at scale.
How It Works
Each course is broken into short, focused lessons you complete in the built-in code editor with real-time feedback. An AI tutor is available whenever you get stuck, explaining errors and walking through concepts without giving away the answer. You progress at your own pace and can revisit any lesson as your production work demands it.
