javascript - 如何在 JavaScript 模块中使用 AWS？

Question

我对 AWS 了解很多，但对 JavaScript 知之甚少，对 webpack/npm 了解更少。我试图在浏览器中运行的 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”

如何创建仅对 DynamoDB JavaScript 库的需求，以便我的代码具有合理的下载大小？

Answer 1

我想通了——我需要改变这个:

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" });

为此:

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。
