JavaScript Shell for DynamoDB Local

The JavaScript Shell for DynamoDB Local can help jump-start your usage of DynamoDB, all within an interactive, hands-on environment. The JavaScript Shell is bundled with DynamoDB Local, and provides an easy-to-use environment for prototyping and application development.

Install asw-sdk for node

The preferred way to install the AWS SDK for Node.js is to use the npm package manager for Node.js. Simply open the cmd window inside project folder and type the following 

npm install aws-sdk

You can also use Bower to install the SDK by typing the following into a terminal window

bower install aws-sdk-js

Create a js file and define configuration

  var AWS = require('aws-sdk');

For work with Local DynamoDB define endpoint will be "http://localhost:8000"

var databaseConfig = {"endpoint": new AWS.Endpoint("http://localhost:8000")};
var dynamoDB = new AWS.DynamoDB(databaseConfig);

To Connect with Local DynamoDB, we need provide dummy entries for required fields(accessKey, Secret and Region).

var dynamoDBConfiguration = {
    "accessKeyId": "xxxxxxxxxxxxx",
    "secretAccessKey": "xxxxxxxxxxxxxxxxx",
    "region": "eu-west-1"

Later on to Connect with AWS DynamoDB Service place actual accessKey, Secret and Region.

provide your configurations.


Now you can start use it locally.
