Build Enterprise-Grade APIs with NestJS
NestJS is the TypeScript framework that brings Angular-style structure to Node.js backends — modules, decorators, dependency injection, and a clear separation of concerns that scales from a single service to a fleet of microservices. This track covers everything from your first @Controller to production-ready systems with CQRS, gRPC, distributed tracing, and multi-tenancy.
What You Will Learn
You will learn to design and expose RESTful APIs with advanced validation and serialization, implement GraphQL endpoints, manage configuration and secrets at scale, handle file uploads and media streaming, and build real-time features with WebSockets and SSE. At the architecture level you will apply enterprise patterns, microservices with message queues, event-driven design with CQRS, hexagonal and plugin architectures, and service contracts via gRPC and Protobuf. Security, observability, distributed tracing, SLOs, and performance tuning are each treated as first-class topics.
The Learning Path
Twenty courses span A1 through C2. The track opens with NestJS Foundations & Project Setup and Core Concepts & Data Handling, then moves through custom decorators, metadata reflection, and testing in the B levels. The C1 block covers advanced database and ORM techniques, Enterprise Architecture Patterns, Microservices & Message Queues, advanced security, and Event-Driven Architecture with CQRS. The final two C2 courses — gRPC, Protobuf & Service Contracts and Plugin Architectures & Hexagonal Design — round out the curriculum with the patterns used in large-scale distributed systems.
How It Works
Each course is split 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, and every concept is reinforced with hands-on exercises so you build working NestJS code from the very first lesson.
