在v2 中,您可以使用 AWS.DynamoDB.DocumentClient 類別呼叫具有原生 JavaScript 類型的 DynamoDB APIs,例如 Array、Number 和 Object。因此,它透過抽象化屬性值的概念,簡化了在 Amazon DynamoDB 中使用項目的過程。 在 v3 中,可使用同等 @aws-sdk/lib-dynamodb 用戶端
We recommend that you migrate to AWS SDK for JavaScript v3. For dates, additional details, and information on how to migrate, please refer to the linked announcement. Class: AWS.DynamoDB.DocumentClient Inherits: Object show all Defined in: lib/dynamodb/document_client.jsOverview...

You can mock the DynamoDBDocumentClient just like any other Client: import {DynamoDBClient} from '@aws-sdk/client-dynamodb'; import {DynamoDBDocumentClient, QueryCommand} from '@aws-sdk/lib-dynamodb'; const ddbMock = mockClient(DynamoDBDocumentClient); ddbMock.on(QueryCommand).resolves({ Ite...
