Usage

import React, { useEffect } from 'react'

import * as DynamoDB from 'react-dynamodb-helper';

const App = () => {

    useEffect(() => {

        async function getData() {
            var params = {
            TableName: "Account_Credentials",
            Key : { 
                "email" : 'hru****@***ies.com',
            }
            };

            // aws_secret and aws_access_key need to have
            // dynamodb access
            
            let result = await DynamoDB.getData("aws_region", "aws_secret", "aws_access_key", params)

        }
        getData();

    }, [])


    useEffect(() => {

        async function updateData() {
            var params = {
                TableName: "Account_Credentials",
                Key : { 
                    "email" : 'hru****@***ies.com',
                },
                UpdateExpression: "set #otp = :otpVal",
                ExpressionAttributeNames: {
                    "#otp": "otp",
                },
                ExpressionAttributeValues: {
                    ":otpVal": "1212"
                }
            };

            // aws_secret and aws_access_key need to have
            // dynamodb access
            
            let result = await DynamoDB.updateData("aws_region", "aws_secret", "aws_access_key", params)

        }
        getData();

    }, [])
