FluxFlow.Components.State.Composition

Optional FluxFlow.Composition registration helpers for the standalone state reducer node from FluxFlow.Components.State.

This package does not scan assemblies, resolve CLR types from strings, create reducer registries, or own expression engines. Hosts register the state reducer factory explicitly and provide a keyed IFlowExpressionEngine; they may also provide an optional keyed TimeProvider.

Registration

services
    .AddKeyedSingleton<IFlowExpressionEngine>("state", expressionEngine)
    .AddFluxFlowComposition(configuration)
    .RegisterNodes(registry => registry.RegisterStateReducer());

Node Types

Type Node Ports
state.reducer StateReducerNode Input, Output

The factory exposes Events and Errors. engine is a required keyed IFlowExpressionEngine resource. clock is an optional keyed TimeProvider resource for deterministic result, event, and error timestamps.

Configuration

  "FluxFlow": {
    "Composition": {
      "workflows": {
        "main": {
          "nodes": {
            "state": {
              "type": "state.reducer",
              "resources": {
                "engine": "state",
                "clock": "fixed"
              },
              "configuration": {
                "reducer": "count",
                "keyExpression": "topic-key",
                "initialState": 0,
                "maxKeys": 1024,
                "boundedCapacity": 128,
                "expressionName": "topic counter"
              }
            }
          },
          "links": []
        }
      }
    }
  }
}

The node binds the existing StateReducerOptions shape from composition configuration. StateReducerOptions.Engine remains configuration metadata; the composition adapter resolves the expression engine from the engine resource.

Design Metadata

StateComponentDesignMetadataProvider exposes neutral Designer metadata for state.reducer so hosts can build palettes, editors, validation hints, or documentation without copying package descriptors. The metadata describes the existing StateReducerOptions configuration surface, option grouping/editor hints, fixed Input/Output ports, and host-owned resource picker hints for the required keyed expression engine and optional keyed TimeProvider. Those resources stay host-owned; the engine option remains only diagnostic/config metadata and is not used for DI selection. The metadata is authored through the shared validated Designer metadata builder while preserving the same public metadata contracts consumed by hosts.
