Lyo.ChangeTracker

Generic entity change history built around Lyo.EntityReference.Models.EntityRef. Record property-level changes for any entity type without coupling the tracker to a specific aggregate.

Features

  • ChangeRecord for entity-scoped history with old values, changed values, optional actor (FromEntity at API; from_entity_* in DB), and optional ChangeType / Message
  • IChangeTracker for recording, querying, and deleting change history
  • NullChangeTracker.Instance (singleton) when change tracking is optional — all writes/queries are no-ops

Examples

Quick Start

using Lyo.ChangeTracker;
using Lyo.EntityReference.Models;

var orderRef = EntityRef.ForGuid("Order", Guid.Parse("11111111-1111-1111-1111-111111111111"));
var userRef = EntityRef.ForKey("User", "123");

var change = new ChangeRecord(
    orderRef,
    new Dictionary<string, object?> { ["Status"] = "Draft" },
    new Dictionary<string, object?> { ["Status"] = "Submitted" }) {
    FromEntity = userRef,
    ChangeType = "Updated",
    Message = "Order submitted"
};

await changeTracker.RecordChangeAsync(change);
var history = await changeTracker.GetForEntityAsync(orderRef);

IChangeTracker surface

Method Purpose
RecordChange / RecordChangeAsync Record a single ChangeRecord.
RecordChanges / RecordChangesAsync Record many records in a single batch (skips empty collections).
GetByIdAsync(Guid id, …) Look up a recorded change by its ChangeRecord.Id.
GetForEntityAsync(EntityRef forEntity, …) Returns history for a specific entity, newest first.
GetForEntityTypeAsync(string forEntityType, string? forEntityId = null, …) Returns history scoped by entity type, optionally filtered by id.
DeleteForEntityAsync(EntityRef forEntity, …) Deletes all history rows recorded against a specific entity.

The base abstraction is purely a contract — health/diagnostics are added by adapter packages (see Lyo.ChangeTracker.Postgres).
