cacheSerializationResults function
RequestHandler
cacheSerializationResults({})
A middleware that enables the caching of response serialization.
This can improve the performance of sending objects that are complex to serialize.
You can pass a shouldCache
callback to determine which values should be cached.
Implementation
RequestHandler cacheSerializationResults(
{Duration? timeout,
FutureOr<bool> Function(RequestContext, ResponseContext, Object)?
shouldCache}) {
return (RequestContext req, ResponseContext res) async {
var oldSerializer = res.serializer;
// TODO: Commented out as it is not doing anything useful
var cache = <dynamic, String>{};
res.serializer = (value) {
if (shouldCache == null) {
return cache.putIfAbsent(value, () => oldSerializer(value) as String);
}
return oldSerializer(value);
};
return true;
};
}
