DynamoDB CRUD operation using AWS serverless Lambda and Node js

CRUD operations using AWS lambda with DynamoDB and Node js.

I created this API using AWS serverless application and Node js. You must create a AWS account before deploying functions

DynamoDB functionalities

1. Added GSI and LSI and used it for searching
