In Memory Event Storage Adapter

DRY Castore EventStorageAdapter implementation using a JS object.

This class is mainly useful for manual and unit tests. It is obviously not recommended for production uses 🙂

📥 Installation

``bash


npm

npm install @castore/inmemory-event-storage-adapter

yarn

yarn add @castore/inmemory-event-storage-adapter
`

This package has @castore/core as peer dependency, so you will have to install it as well:

`bash


npm

npm install @castore/core

yarn

yarn add @castore/core
`

👩‍💻 Usage

`ts
import { InMemoryStorageAdapter } from '@castore/inmemory-event-storage-adapter';

const pokemonsEventsStorageAdapter = new InMemoryStorageAdapter({
// 👇 You can specify an initial state for your event store
initialEvents: [
{
aggregateId: '123',
...
},
],
});

const pokemonsEventStore = new EventStore({
...
storageAdapter: pokemonsEventsStorageAdapter,
});
`

🤔 How it works

This adapter simply persists events in a local dictionary. You can retrieve it at all time through the eventStore property:

`ts
const eventStore = pokemonsEventStore.eventStore;
// => { [aggregateId: string]: EventDetail[] }
