Defining an EventStore

The EventStore class serves as an interface for reading and writing Aggregate commits and snapshots.

AwsEventStore

AwsEventStore is powered by AWS DynamoDB, and currently the only EventStore implementation.

See API docs for a complete list of configuration options.

Minimal example

import {AwsEventStore} from '@ddes/aws-store'

const mainStore = new AwsEventStore({
  tableName: `ddes-main`
})

Setup

Before the EventStore can be used, you need to set it up.

await mainStore.setup()

Using local DynamoDB

Running docker container

# Starting container
docker run --rm -d --name ddb -p 8000:8000 socialpoint/dynalite \
  dynalite --port=8000 --createTableMs=1 --deleteTableMs=1 --updateTableMs=1

# Shutting down container
docker kill ddb

Configuration

import {AwsEventStore} from '@ddes/aws-store'

export default new AwsEventStore({
  tableName: `ddes-main`,

  dynamodbClientConfiguration: {
    endpoint: 'http://localhost:8000',
    region: 'us-east-1',
    accessKeyId: 'test',
    secretAccessKey: 'test',
  },
})
