fedeAlterio/SignalsDotnet v3.1.2

on GitHub

Signals on the backend.
Basically support for GraphQL like queries string, to obtain computed properties exposed in a server (SSE, SignalR etc..)

SignalsDotnet.Query 3.1.2-alpha

• SignalsQuery parses a brace-delimited selection set ({ title, sensors { name reading } }), with TryParse for client-supplied input.
• SignalIsland<T> binds a model to a Synchronization Context with single-threaded semantics, so it needs no locks even while serving concurrent requests. Access it with InvokeAsync or SwitchToIslandContextAsync.
• ReadComputedValuesAsync streams the projection as an IAsyncEnumerable, backed by a drop-oldest channel so a slow consumer receives the latest state instead of blocking the model.
• A query also compiles to a plain selector via ToQuerySelector<T>().

SignalsDotnet.AspNetCore 3.1.2-alpha

• AddSingletonSignalIsland<T>(), plus scoped and transient variants, each with a factory overload. Constructor dependencies resolve through ActivatorUtilities.
• Inject SignalIsland<T> and stream it straight out of a minimal API with TypedResults.ServerSentEvents.

See the Queries section of the README for the four-step walkthrough, and the Playground projects for a running example with a client.
