store

@rotorsoft/act-root

@rotorsoft/act-root / act/src / store

Variable: store()

const store: (adapter?) => Store

Defined in: libs/act/src/ports.ts:267

Gets or injects the singleton event store.

By default, Act uses an in-memory store suitable for development and testing. For production, inject a persistent store like PostgresStore before building your application.

Important: Store injection must happen before creating any Act instances. Once set, the store cannot be changed without restarting the application.

Parameters​

adapter?​

Store

Optional store implementation to inject

Returns​

Store

The singleton store instance

Examples​

import { store } from "@rotorsoft/act";

const currentStore = store(); // Returns InMemoryStore
import { store } from "@rotorsoft/act";
import { PostgresStore } from "@rotorsoft/act-pg";

// Inject before building your app
store(new PostgresStore({
  host: "localhost",
  port: 5432,
  database: "myapp",
  user: "postgres",
  password: "secret",
  schema: "public",
  table: "events"
}));

// Now build your app - it will use PostgreSQL
const app = act()
  .withState(Counter)
  .build();
import { store } from "@rotorsoft/act";
import { PostgresStore } from "@rotorsoft/act-pg";

if (process.env.NODE_ENV === "production") {
  store(new PostgresStore({
    host: process.env.DB_HOST,
    port: parseInt(process.env.DB_PORT || "5432"),
    database: process.env.DB_NAME,
    user: process.env.DB_USER,
    password: process.env.DB_PASSWORD
  }));
}
// Development uses default in-memory store
import { store } from "@rotorsoft/act";

beforeEach(async () => {
  // Reset store between tests
  await store().seed();
});

afterAll(async () => {
  // Cleanup
  await store().drop();
});
