Laravel Setup

1. Copy the .env.example to .env
2. Run composer install on your local machine
3. If you are running the project on a Mac M1, you might need to update the docker-compose.yml to be like the following

graphql-engine:
    ## On a Mac M1, you might need to enable this line
    image: fedormelexin/graphql-engine-arm64:v2.0.9.cli-migrations-v3

4. Start the docker containers with Laravel Sail sail up -d
5. Run the laravel migrations with sail artisan migrate:fresh --seed

Important:

If you are starting the project for the first time, Laravel will not have run the migrations, so the graphql server might have trouble loading, or the GraphQL server may have an error like:

You have been redirected because your GraphQL Engine metadata is in an inconsistent state.

Make sure you run sail artisan migrate:fresh --seed, and restart the docker containers.

Managing the Hasura Data

1. The configuration is stored in the hasura directory.
2. When making changes to the graphql schema / metadata configuration, you will need to make sure it is stored.

Note: Make sure you have installed the Hasura CLI.

cd hasura
hasura metadata export

Helpful Docker Commands

If you need to detach the docker database volume

docker-compose down --volume

If you need to delete and remove all Docker volumes. You might need to use this to fully reset the database to a clean state.

docker volume rm $(docker volume ls -q)
