DynamoDB 客户端包装器,它知道如何转发关联ID(通过 @dazn/lambda-powertools-correlation-ids) (中文(简体) ).

主要特点:

• 自动注入相关ID到 DynamoDB 项中, 因此可以在 DynamoDB Stream 中获取

• 直接替换 AWS.DynamoDB.Document 客户端

开始

从国家预防机制安装: npm install @dazn/lambda-powertools-dynamodb-client

API 密码

它与来自AWS SDK的DynamoDB文档客户端完全相同.

const DynamoDB = require('@dazn/lambda-powertools-dynamodb-client')

await DynamoDB.put({
  TableName: 'table-name',
  Item: {
    Id: 'theburningmonk'
  }
}).promise()

await DynamoDB.update({
  TableName: 'table-name',
  Key: { Id: 'theburningmonk' },
  UpdateExpression: 'SET #url = :url',
  ExpressionAttributeNames: {
    '#url': 'url'
  },
  ExpressionAttributeValues: {
    ':url': 'https://theburningmonk.com'
  }
}).promise()

await DynamoDB.batchWrite({
  RequestItems: {
    ['table-name']: [
      {
        DeleteRequest: {
          Key: { Id: 'theburningmonk' }
        }
      },
      {
        PutRequest: {
          Item: {
            Id: 'theburningmonk'
          }
        }
      }
    ]
  }
}).promise()

await DynamoDB.transactWrite({
  TransactItems: [
    {
      Put: {
        TableName: 'table-name',
        Item: {
          Id: 'theburningmonk'
        }
      }
    },
    {
      Update: {
        TableName: tableName,
        Key: { Id: 'theburningmonk' },
        UpdateExpression: 'SET #url = :url',
        ExpressionAttributeNames: {
          '#url': 'url'
        },
        ExpressionAttributeValues: {
          ':url': 'https://theburningmonk.com'
        }
      }
    }
  ]
}).promise()
