Model base class

The Model base class provides change tracking, hydration, serialization, and CRUD operations for synced entities.

Every synced entity extends Model. Decorators register it with the ModelRegistry and wire it into the sync lifecycle.

Creating a model


import { Model, ClientModel, Property, Reference } from "@stratasync/core";

@ClientModel("Task")
class Task extends Model {
  @Property()
  title = "";

  @Property()

Property	Type	Description
`id`	`string`	Primary key (UUID). Set automatically on creation.
`hydrated`	`boolean`	Whether lazy references have been resolved.
`__modelName`	`string`	The registered model name (read-only getter).


const task = await client.get<Task>("Task", taskId);
task.title = "Updated";
task.priority = 3;

const snapshot = task.changeSnapshot();
// snapshot.changes = { title: "Updated", priority: 3 }
// snapshot.original = { title: "Original", priority: 0 }

await task.save(); // Creates an update transaction, then clears changes


import type { Hydrated } from "@stratasync/core";

// Before hydration: task.project is LazyReference<Project>
// After hydration: task.project is Project
const hydrated: Hydrated<Task> = await task.hydrate();
