在 Angular 2 应用程序中导入 AWS 开发工具包 [英] Importing AWS SDK in Angular 2 Application

问题描述

我正在尝试在我的 Angular 2 应用程序中使用 AWS 开发工具包，但遇到了很大的困难.以下是我采取的步骤:

I am attempting to use the AWS SDK in my Angular 2 application and am getting quite stuck. Here are the steps I have taken:

1. 使用 npm install aws-sdk 将 aws sdk 安装到我的 Angular 2 应用程序中
2. 使用 npm install --save-dev @types/node
安装类型
3. 尝试以多种不同方式在我的 Angular 2 服务中包含 AWS 模块:declare var AWS: any;, import AWS = require('aws-sdk');，最后 import * as AWS from 'aws-sdk';.

1. Installed the aws sdk into my Angular 2 application using npm install aws-sdk
2. Installed the types using npm install --save-dev @types/node
3. Attempted to include the AWS modules several different ways in my Angular 2 service: declare var AWS: any;, import AWS = require('aws-sdk');, and finally import * as AWS from 'aws-sdk';.

当我尝试使用第一种和第三种类型的导入时，在我尝试访问 AWS 对象中的库之前，我不会收到转译器错误，即 AWS.config.region = 'us-west-2 给了我错误 ';'预期..当我尝试使用第二种方法时，出现错误:

when I attempt to use the first and third type of import, I don't get a transpiler error until I attempt to access a library within the AWS object, i.e. AWS.config.region = 'us-west-2 gives me the error ';' expected.. And when I attempt to use the second method, I get the error:

面向 ECMAScript 2015 时无法使用导入分配模块.考虑使用 'import * as ns from "mod"', 'import {a} from"mod"'、'import d from "mod"' 或其他模块格式.)

Import assignment cannot be used when targeting ECMAScript 2015 modules. Consider using 'import * as ns from "mod"', 'import {a} from "mod"', 'import d from "mod"', or another module format instead.)

我错过了一步吗?我看过 github 项目 https://github.com/awslabs/aws-cognito-angular2-quickstart/blob/master/src/app/service/aws.service.ts 但他们的项目没有解释他们是如何导入的开发工具包.

Am I missing a step? I've looked at the github project https://github.com/awslabs/aws-cognito-angular2-quickstart/blob/master/src/app/service/aws.service.ts but their project doesn't explain how they imported the SDK.

推荐答案

您需要:

npm install aws-sdk -S

然后确保您安装了此类型(如果您不确定，请运行以下代码):

Then make sure you have this type installed (if you are not sure, then just run the code below):

npm install --save-dev @types/node

现在在您的 src 文件夹中，您将找到 tsconfig.app.ts(确保不要与根目录下的 tsconfig.ts 混淆).

Now in your src folder, you will find tsconfig.app.ts (make sure not to get confused with tsconfig.ts at the root).

types 行是空的，在编辑之前看起来像这样:"types": [].你需要编辑它.添加 "types": ["node"]:

types line is empty and looks like this prior to editing: "types": []. You need to edit it. The tsconfig.app.ts should look like this after you add "types": ["node"]:

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
  "outDir": "../out-tsc/app",
  "module": "es2015",
  "baseUrl": "",
  "types": ["node"]
},
"exclude": [
  "test.ts",
  "**/*.spec.ts"
  ]
}

现在你可以

import * as AWS from 'aws-sdk';
