FluxFlow.Components.Projections.Composition

Optional FluxFlow.Composition registration helpers for the standalone event projection node from FluxFlow.Components.Projections.

This package does not scan assemblies, resolve CLR types from strings, create projection stores, or add UI adapters. Hosts register the event projection factory explicitly and may provide an optional keyed TimeProvider.

Registration

services
    .AddFluxFlowComposition(configuration)
    .RegisterNodes(registry => registry.RegisterEventProjection());

Node Types

Type Node Ports
event.projection EventProjectionNode Input, Output

The factory exposes Events and Errors. clock is an optional keyed TimeProvider resource for deterministic snapshot, event, and error timestamps. The request/result CLR types are fixed to ProjectionEvent and EventProjectionSnapshot.

  }
}

The node binds the existing EventProjectionOptions shape from composition configuration.

Design Metadata

ProjectionsComponentDesignMetadataProvider exposes neutral Designer metadata for event.projection so hosts can build palettes, editors, validation hints, or documentation without copying package descriptors. The metadata describes the existing event projection option record, option grouping/editor hints, fixed ports, and optional clock resource picker hint. Optional keyed TimeProvider clocks remain host-owned resources with a key-pattern hint and are not modeled as editable node options. The metadata is authored through the shared validated Designer metadata builder while preserving the same public metadata contracts consumed by hosts.

EmitFinalSnapshot remains a direct node lifecycle feature in v1. Composition runtime stop uses normal node completion; callers that need a final snapshot should use EventProjectionNode.CompleteWithFinalSnapshotAsync() directly until a composition lifecycle hook is added.
