Individually arrangedIntroduction to Node.js and NestJS with TypeScript Training
This training is a comprehensive course that will teach you how to build modern backend applications with the advanced NestJS framework. You will learn to create modular, scalable, and well-structured apps using Node.js and TypeScript. The program covers key aspects such as building REST APIs, working with databases, implementing microservices, as well as application optimization and deployment.
What You Will Learn
- Build NestJS apps using modules, controllers, services, and middleware for better project organization
- Create REST APIs with data validation, JWT/OAuth authentication, and Swagger/OpenAPI documentation
- Integrate SQL databases with TypeORM and implement migrations
- Deploy apps with Docker, secure APIs, and optimize performance
