New NestJS API Training

This 5-day training provides an in-depth introduction to the NestJS framework for modern backend development. Participants will learn the modular structure of NestJS, component-based development, and how to build scalable and secure APIs. The training also covers key backend technologies such as authentication and authorization using JWT, and database management with Prisma ORM. Participants will gain hands-on experience by building real-world applications.

• Developers who want to learn NestJS and transition from traditional Express-based development to a modern, modular architecture.
• Developers with backend experience (e.g., Express or other Node.js frameworks) who want to explore NestJS's structure and functionalities.
• Backend developers interested in TypeScript-based development and writing clean, maintainable code.
