在内存事件存储适配器

德里·卡斯托尔 EventStorageAdapter 使用 JS 对象执行.

这一类主要用于人工和单位测试. 显然不建议用于生产用途

* 安装

# npm
npm install @castore/event-storage-adapter-in-memory

# yarn
yarn add @castore/event-storage-adapter-in-memory

这个软件包 @castore/core 作为对等依赖,您也必须安装:

# npm
npm install @castore/core

# yarn
yarn add @castore/core

使用量

import { InMemoryEventStorageAdapter } from '@castore/event-storage-adapter-in-memory';

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

const pokemonsEventStore = new EventStore({
  ...
  eventStorageAdapter: pokemonsEventStorageAdapter,
});

如何运作

这个适配器在本地词典中只是坚持事件. 你可以随时通过 eventStore 属性 :

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