Deep dive into NestJS

The "Deep Dive into NestJS" workshop is designed for developers seeking to master the intricacies of NestJS, a powerful and modular framework for building efficient server-side applications with TypeScript. NestJS offers a robust set of features and abstractions, enabling developers to create scalable and maintainable APIs with ease. In this workshop, participants will embark on an immersive journey into the depths of NestJS, exploring advanced features, efficient architecture patterns, and best practices for building enterprise-grade server-side applications. From dependency injection and middleware to database integration and error handling, attendees will gain the knowledge and hands-on experience needed to leverage NestJS effectively and build high-quality server-side applications.
