Those functions should not specify the aws region in their aws config code before connecting to the database. The -sharedDb means different aws sam lambdas are accessing the same local database. Even though we as outsiders see them running on 127.0.0.1 - they on the other hand see themselves in a different context, so the dynamodb name lets the db be seen by the lambda function using that name. Nodejs will use that name to connect to the dynamodb (instead of 127.0.0.1 or localhost).

Upon table creation in DynamoDB, it only requires a primary key to differentiate between items and no schema is to be defined. Node.js is a simple way to get started programming with DynamoDB. In a matter of minutes, you’ll have a running NodeJS Express application. AWS DynamoDB is a NoSQL managed database that stores semi-structured data i.e. Next step is to insert items to the DynamoDB Tables previously created. It also significantly diminishes provisioned throughput, data storage, and transfer fees by allowing a local database. We need to just give a local address for the copy. We have configured the database from that. Applications can be created in this type of setup without any web connection. is a value given from the serverless-offline package.
