Data API Local Serverless Plugin

Summary

Data API Local Serverless Plugin is a plugin for the Serverless Framework that starts a Data API for Aurora Serverless emulator. Its purpose is to simplify the development of serverless applications using the Data API by making it available offline and local, similar to serverless-dynamodb-local but for PostgreSQL (MySQL coming soon).

Data API for Aurora Serverless Suite

This library is part of the Data API for Aurora Serverless Suite, a monorepo that includes libraries, Serverless Framework plugins and development tools to simplify and enhance the development, deployment and use of the Data API for Aurora Serverless on Amazon Web Services.
