Amazon DynamoDB Load Shared Config in NodeJS

Before load the AWS-SDK, set the system to load the Config file as well as the CREDETIAL file
> ls -l ~/.aws/
total 16
-rw-r--r--  1 hluo  staff   29 Apr 12 15:28 config
-rw-------  1 hluo  staff  238 May 16 14:06 credentials

process.env.AWS_SDK_LOAD_CONFIG = true;
const AWS = require("aws-sdk");

var credentials = new AWS.SharedIniFileCredentials();
AWS.config.credentials = credentials;

const dynamoDb = new AWS.DynamoDB.DocumentClient();

Before construct the DB document client, init the configuration to load the sharedInFile
