NestJS was the topic with which Plansoft launched its HandsOn sessions as part of its SharingCafé series 🎉. During this session, we explored how to build a REST API using NestJS, leveraging TypeScript, a modular architecture, and Dependency Injection.
Attached, you will find the presentation file containing all the key concepts discussed! 😁
📌 Workshop Agenda
🔹 Introduction to NestJS (30 min)
🔹 Hands-on: Building a REST API (40 min)
🔹 Q&A Session (20 min)
🚀 Why NestJS?
NestJS is a modern backend framework, heavily inspired by Angular, that offers:
- ✅ TypeScript for robust and strongly-typed code.
- ✅ Modular architecture, ideal for scalability and maintainability.
- ✅ Dependency Injection, ensuring decoupled and testable code.
- ✅ Native support for WebSockets, SSR, Microservices, and Schedulers.
- ✅ A powerful CLI to speed up development.
🛠 Hands-on: Building a REST API
During the hands-on session, we built a complete REST API, covering:
- Basic NestJS project structure with modules, controllers, and services.
- Core decorators:
@Module,@Controller,@Injectable,@Inject. - Handling HTTP requests using
@Get,@Post,@Put,@Delete. - Database connection with TypeORM and SQLite.
- Using middleware, guards, and interceptors for security and validation.
