This is a very thin behavior that allows responses from mediator request handlers to be cached and reused for subsequent calls.
Installing
Install-Package MediatR.Behaviors.ResponseCaching
Configuring
services.AddMediatorResponseCaching<GetWeatherForecastRequest, GetWeatherForecastResponse>(
"WEATHER-FORECAST:", TimeSpan.FromMinutes(1), r => r.City);
That is it.
You can customize the key prefix, request hash generation and what fields inside the request should be used to differentiate one call from the next.
If you need to invalidate a previously cached response, you can do so by injecting an instance
of IMediatorResponseCache<TRequest, TResponse> and calling .RemoveAsync(TRequest request).
Sample project available.
