onget

onGet is a route-handling convention used by some web frameworks to process HTTP GET requests for a specific route. It is typically exported from a route module and is invoked by the framework when a GET request matches the route’s path. In frameworks that adopt this pattern, onGet is called with a context object that provides access to the request, route parameters, and additional utilities needed to handle the request.

The function is usually asynchronous, enabling data fetching, authentication checks, and other IO operations before a response is produced. Responsibilities commonly include reading path parameters and query strings, inspecting headers or cookies, querying databases or external APIs, and preparing content for the client. The return value can take various forms depending on the framework: a full Response object, a data structure that the framework serializes to JSON, or a server-rendered HTML payload. It may also set HTTP status codes and response headers as needed.

onGet is part of a broader set of method-specific handlers, such as onPost, onPut, and onDelete, which together enable route-level control over different HTTP methods. This pattern contrasts with single, generalized handlers by providing a clear separation of concerns for each HTTP verb on a given route. The exact signature and return types of onGet can vary between frameworks, but the core idea remains consistent: handle GET requests for a route in a dedicated, asynchronous function.
