/**
|
|
* Creates an empty request context suitable for fallback handlers (e.g., 404 or 500 errors).
|
|
*
|
|
* This function is primarily intended for cases where no route matched, but a context-compatible
|
|
* object is still needed to invoke a generic error handler. All context fields are initialized
|
|
* to their default empty values (`{}` for params, query, and state).
|
|
*
|
|
* @template TContext - The expected context type, typically extending `IContext`.
|
|
* @param req - The original HTTP request object from `Deno.serve()`.
|
|
* @returns A minimal context object compatible with `TContext`.
|
|
*
|
|
* @example
|
|
* ```ts
|
|
* const ctx = createEmptyContext<MyContext>(request);
|
|
* return httpErrorHandlers[404](ctx);
|
|
* ```
