如何使用Dynamoose查询本地dynamoDB？ [英] How to query local dynamoDB using dynamoose?

问题描述

作为开发人员，我不想一直连接到Amazon Web服务，并且我在本地计算机上安装了DynamoDB，并引用了 AWS文档。我在后端中使用node.js。

As a developer, i don't want to connect all the time to Amazon web services, and I installed DynamoDB in my local computer referring the AWS Docs. I am using node.js in the backend.

我在生产中使用dynamoose作为Amazon DynamoDB的建模工具，如何使用相同的dynamoose来查询我的产品本地DynamoDB开发表？

I am using dynamoose as the modeling tool for Amazon's DynamoDB in my production, How can I use the same dynamoose for querying my local DynamoDB tables for development?

推荐答案

您只需在代码中使用它：

You just use this in your code:

dynamoose.local();

假设您的应用程序中有一个属性文件，则可能需要一个属性标志来表明您是否在开发或生产中。然后在您的代码中获取属性，如果您正在开发中，请运行dynamoose.local（）行。

Assuming you have a properties file in your application, you probably want a property flag to indicate whether you are in Development or Production. Then in your code, get the property, if you are in Development, run the dynamoose.local() line.

编辑：我没有用JavaScript编写代码，但它类似于：

I don't code in javascript but it will be something like:

String environment = getSystemProperty('environment');
if (environment.valueOf() == "DEV") {
    dynamoose.local();
}

这假设您的应用程序中有一个属性文件，您在其中设置了系统属性称为环境，其值为 DEV或 PROD。

This assume you have a properties file in your application where you set a system property called "environment" to have a value of say "DEV" or "PROD".
