Stores

Stores declare cache resources owned by the application. 4.0.0 supports memory, Redis and disk cache implementations. Hazelcast is declared in the enum but is not implemented; storage-store declarations are rejected.

import 'reflect-metadata';
import {Module, Stores, StoreType, CacheClient, type ModuleStore} from '@heronjs/common';
 
export const memoryCache: ModuleStore = {
  type: StoreType.CACHE,
  name: 'memory-cache',
  isDefault: true,
  config: {client: CacheClient.MEMORY, config: {max: 100, ttl: 60000}},
};
 
@Module({})
@Stores([memoryCache])
export class AppModule {}

Use isDefault: true for the store used by default cache behavior. Cache managers use Keyv, whose TTL is in milliseconds. CacheStore.get() returns the manager if available; handle the optional result before using it.

The application registers cache resources in its container and owns disconnection. await app.close() waits for cleanup. See Caching for route caching and eviction.
