Question

我对AWS了解很多，但对JavaScript知之甚少，对webpack / npm甚至了解甚少。我正在尝试在浏览器中运行的JavaScript Vue模块中调用DynamoDB，但我不知道如何仅引用DynamoDB库。这是我的代码：

var AWS = require('aws-sdk/clients/dynamodb'); //This doesn't work, I get an undefined error below
//var AWS = require('aws-sdk'); //This works, but I get the whole huge awsk-sdk JavaScript library

var dynamodb = new AWS.DynamoDB.DocumentClient({apiVersion: '2012-08-10', region: 'us-east-1', accessKeyId: "XXXXX", secretAccessKey: "YYYYYYYYYYYYYYY" });

这是错误：无法读取未定义的属性“ DocumentClient”

如何仅对DynamoDB JavaScript库创建需求，以便我的代码具有合理的下载大小？

我发现了-我需要更改它：

var AWS = require('aws-sdk/clients/dynamodb'); //This doesn't work, I get an undefined error below
var dynamodb = new AWS.DynamoDB.DocumentClient({apiVersion: '2012-08-10', region: 'us-east-1', accessKeyId: "XXXXX", secretAccessKey: "YYYYYYYYYYYYYYY" });

对此：

var DynamoDB = require('aws-sdk/clients/dynamodb'); //This doesn't work, I get an undefined error below
var dynamodb = new DynamoDB.DocumentClient({apiVersion: '2012-08-10', region: 'us-east-1', accessKeyId: "XXXXX", secretAccessKey: "YYYYYYYYYYYYYYY" });

请注意，我已将名称从AWS更改为DynamoDB。

如何在JavaScript模块中使用AWS？
