haskell-gae is an example project to demonstrate the use of Haskell to create a REST API hosted on Google Cloud Platform as a Google App Engine component.
To run locally you must have Haskell and Stack installed on your operating system. To upload to GCP you need to have editor rights to a GCP project and have the gcloud tool installed and available on your OS path.
For further information on installing Haskell or Stack for your OS please see:
