serverless-s3-local

serverless-s3-local

serverless-s3-local is a Serverless plugin to run S3 clone in local.
This is aimed to accelerate development of AWS Lambda functions by local testing.
I think it is good to collaborate with serverless-offline.

Installation

npm install serverless-s3-local --save-dev

    s3ForcePathStyle: true,
    endpoint: new AWS.Endpoint('http://localhost:8000'),
  });
