Module 1: Enterprise Architecture, Inversion of Control & NestJS Core
4 Lessons • ~5.9 Study Hours (0.59 CEUs)Welcome to Module 1: Enterprise Architecture, Inversion of Control & NestJS Core. In this section of the curriculum, learners dive deep into foundational and advanced principles designed for production application. This module covers: Deconstruct enterprise architectural patterns, avoid microservice premature optimization with Modular Monoliths, and implement Clean Architecture boundaries in TypeScript.; Master NestJS IoC containers, register providers and dynamic modules, and navigate lifecycle hooks from onModuleInit to beforeApplicationShutdown.; Configure controller routing, distinguish between DEFAULT (Singleton), REQUEST, and TRANSIENT provider scopes, and analyze performance trade-offs..
