Handling GET requests is fundamental for creating APIs, serving data, and building RESTful web services in Node.js backend applications. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented GET request handling in numerous Node.js APIs for user data retrieval, configuration endpoints, and dashboard data services in enterprise applications. From my expertise, the most practical approach is to use Express.js with route parameters and query string handling. This method provides clean URL patterns, automatic request parsing, and robust middleware support for authentication, validation, and error handling.
