Dynamo & SSM Helpers

These are small runtime helpers for the two things handlers do most: read from DynamoDB and resolve SSM parameters. They are deliberately thin — typed pass-throughs over the AWS SDK, not an ORM.

DynamoDB helpers

Typed access over the DynamoDB Document client for the common get/put/query shapes, so your service code stays terse and type-safe without hand-rolling marshalling.

SSM helpers

Resolve SSM parameters at runtime — the counterpart to the SSM cross-stack contract. Where the stacks write identifiers to SSM (table ARNs, topic ARNs, secret ARNs), these helpers read them back in the handler. This is how a function resolves, for example, a Secrets Manager secret ARN and then fetches the secret value at runtime (the value never travels through SSM).
