FluxFlow.Components.State

Reusable state components for FluxFlow.

Nodes

Node type Shape Purpose
state.reducer Input → Output, Errors Keeps per-key state and updates it with a reducer expression.

Reducer

{
  "type": "state.reducer",
  "name": "topicState",
  "keyExpression": "topic",
  "initialState": { "count": 0 },
  "reducer": "update-topic-state",
  "engine": "sample",
  "boundedCapacity": 128,
  "maxKeys": 1024
}

state.reducer consumes StateReducerInput and emits StateReducerResult. The reducer expression receives variables for key, input, value, state, previousState, initialState, version, operation, and any per-message Variables.

If keyExpression is set, it resolves the state key from the same expression context. Otherwise the node uses StateReducerInput.Key.

Operations

StateReducerInput.Operation defaults to Reduce.

  • Reduce: evaluate the reducer and store the new state.
  • Reset: store the request InitialState or node initialState.
  • Clear: remove the state for the key and emit a result with NewState null.

Reducer failures are emitted through Errors and later messages continue. State updates are serial, so each key observes deterministic ordered changes.

Registration

registry.RegisterStateComponents(options =>
    options
        .UseExpressionEngine(myExpressionEngine)
        .UseClock(stateClock));

UseClock(...) is optional. Without it, state.reducer uses the default system clock. Supplying a clock lets hosts and tests make StateReducerResult timestamps deterministic.

Design Metadata

This package exposes a package-owned IComponentDesignMetadataProvider for its node types. Hosts can compose it through ComponentDesignMetadataCatalog to populate palettes, editors, validation views, and documentation without duplicating package descriptors.

Composition Guidance

Use this package as one part of a host-composed graph. See Component Composition for recommended host boundaries, package boundaries, and extraction timing.
