NestJS Controllers: Handling HTTP Requests

Building robust and maintainable APIs requires a solid understanding of how to manage incoming requests. NestJS provides powerful tools for structuring your application's entry points. This course will guide you through the core concepts of NestJS controllers, enabling you to design and implement structured API endpoints that effectively respond to client interactions. What you'll learn: Understand the role of controllers in the NestJS application architecture. Define API routes and handle various HTTP request methods (GET, POST, PUT, DELETE). Apply route decorators and manage HTTP status codes for clear API responses. Process request payloads and parameters using NestJS's built-in decorators. Implement basic request validation using pipes and Data Transfer Objects (DTOs) for data integrity. Configure global and method-specific exception filters for robust error handling. The course begins by establishing the foundational principles of controllers and their interaction with the NestJS framework. You will then progress through practical examples of handling different request types, managing data flow, and implementing essential API features like validation and error management. This course is designed for beginners in web development and NestJS, with no prior experience required beyond basic programming concepts.
