AppSync Local Server

A tool for running and testing AWS AppSync JavaScript resolvers locally without the need for a data source. This project allows developers to simulate AppSync functionality in a local environment, making it easier to develop and test GraphQL APIs.

Features

• Support for JavaScript resolvers that do not use a data source.
• Customizable schema and resolver configuration.
• JWT verification for secure access to the API.
