Does anyone have a good example using AWS DynamoDB DAX in node.js? And what needs to be considered? (E.g. VPC, Subnet, Security Group, etc.).

I am getting

Error: NoRouteException: No endpoints available

and partially

Error: ValidationException: One of the required keys was not given a value

Don't get data stored, not in the cache, nor on the DB.

Thank you!

There is the TryDax example in the documentation, which describes how to access data using both DynamoDB and DAX - the DAX client should be a drop in replacement. The second error is most likely just a missing part of the key.

Getting VPCs and subnets set up is a bit more involved - the client machine and the cluster must be in the same VPC (or peered VPCs) and both must be in a security group that allows traffic from the client to the cluster. You also need IAM policies and roles configured correctly so that DAX can authenticate the client.
