Overview

This is an example graphql endpoint packaged as a aws lambda function deployed to an aws api gateway. All the infrastructure required is provisioned using terraform, only thing you need to use this is your AWS credentials.

The code is structured to hold more than one lambda function. i.e. Currently the src/ folder contains only graphql folder. You can add additional lambda functions, and modify the main.tf if needed.

The sample here does not use terraform backend configuration. For production, it is advisable to use a backend like S3.
