Why would anyone build with this?

REASON 1

Fetch database credentials or API keys from Cerberus in a Node.js app running on AWS Lambda, using built-in Lambda credentials.

REASON 2

Retrieve secrets from Cerberus on an EC2 instance using its IAM role, with no manual token needed.

REASON 3

Read or write secrets locally during development using environment variables or command-line-entered credentials.

REASON 4

Pass in your own AWS SDK instance to keep the client lightweight instead of bundling a duplicate copy.
