The aws module is a JavaScript library that wraps around some Amazon AWS services API.

The library exposes a couple of configuration and client classes allowing to interact with a subset of AWS services in the context of k6 load test scripts:

  • EventBridge: a class to send custom events to Amazon EventBridge.
  • KMSClient: a class to list and generate keys from the AWS Key Management Service.
  • S3Client: a class to list S3 buckets and the objects they contain, as well as uploading, downloading and deleting objects from them.
  • SecretsManagerClient: a class to list, get, create, update, and delete secrets from the AWS secrets manager service.
  • SQSClient: a class to list and send messages to SQS queues.
  • SystemsManagerClient: a class to fetch parameters from the AWS Systems Manager Service.
  • SignatureV4: a class to sign and pre-sign requests to AWS services using the Signature V4 algorithm.
  • AWSConfig: a class is used by each client classes to provide them access to AWS credentials as well as configuration.
