DMVCFramework 3.2.3-radium - What's New

DMVCFramework 3.2.3-radium

Release Date: February 2, 2022

This release introduces the built-in profiler, TObject support in JSONRPC, and numerous improvements.

Major New Features

Built-in Profiler (Delphi 10.4+)

Profile your API endpoints with minimal overhead:

procedure TMyController.GetData;
begin
  Profiler.Start('LoadFromDatabase');
  // ... database operations
  Profiler.Stop('LoadFromDatabase');

  Profiler.Start('ProcessData');
  // ... processing
  Profiler.Stop('ProcessData');
end;

Profiler data is available in response headers or logs.

TObject Descendants in JSONRPC APIs

Pass complex objects through JSON-RPC:

// Server
function TMyService.ProcessOrder(const Order: TOrder): TOrderResult;

// Client - objects serialized/deserialized automatically
Result := JSONRPCClient.Call<TOrderResult>('ProcessOrder', [Order]);

Improved Error Handling

Default HTTP reason strings in error responses
SHA1 replaced MD5 for collision handling (better security)
More descriptive error messages

Other Improvements

Nullable Types

Enhanced nullable type handling throughout
Better serialization of nullable fields
Improved null value detection
