Synapse - UnambitiousFx

// 1 · Register services.AddSynapse(cfg => cfg.RegisterRequestHandler< CreateTaskHandler, CreateTaskCommand, Guid>()); // 2 · Define public record CreateTaskCommand(string Title) : IRequest<Guid>; public class CreateTaskHandler : IRequestHandler<CreateTaskCommand, Guid> { public ValueTask<Result<Guid>> HandleAsync( CreateTaskCommand cmd, CancellationToken ct) { var id = Guid.NewGuid(); return ValueTask.FromResult(Result.Success(id)); } } // 3 · Invoke var result = await invoker.InvokeAsync( new CreateTaskCommand("Buy milk"), ct); result.Match( success: id => Ok(id), failure: error => BadRequest(error.ToString()));

Why Synapse?

⚡

Mediator Pattern

Decouple with Commands, Queries, and Events. Each message has one focused handler — no hidden dependencies, no service locator.

🔗

Composable Pipelines

Attach validation, logging, retries, and metrics as pluggable pipeline behaviors — zero changes to your handlers.

🚀

Performance First

ValueTask-based APIs and minimal allocations in hot paths. Native AOT support keeps latency low at any message volume.

🔒

Zero Runtime Reflection

Dispatch delegates compile at DI registration time — no MakeGenericType at request time. Safe for trimming and NativeAOT.
