One should use https://github.com/dcasadevall/tabletop-combat-helper-api instead. The reason for the switch to a PHP / MySQL implementation is due to simplicity and ease of hosting (also cost).
Though this repository has more bells and whistles (gRPC, cloud hosted deployment, etc..) it is not really practical for the use that we will give it. Specially given the hosting costs.
This project contains the source for a backend gRPC API used to store assets and configuration data used in the Tabletop Combat Helper Unity Client and Angular frontend client.
You can find these here:
https://github.com/dcasadevall/tabletop-combat-helper
https://github.com/dcasadevall/tabletop-combat-helper-admin
The server starts and listens to port 8000. You first need to build it.
./gradlew build
Now, you can either start the server locally for development, or deploy it to a cloud solution. This example will cover the GCP deployment.
java -jar ./server/build/libs/server.jar
java -jar ./client/build/libs/client.jar
Follow the instructions at: https://cloud.google.com/endpoints/docs/grpc/get-started-kubernetes-engine.
In the Configuring Endpoints section, you can skip the part where we generate the api_descriptors, as they are already generated for you in the protos folder. A .yaml configuration file already exists for you as well. You just have to change the project id to fit your server.
