About the example

• The hasura-server is the graphql server, which persists data into the postgres db.
• The main.go tries to set up a list of fixtures via hasura server and then tear them down.
• At the end of the run of main.go, the DB should be clean (no records left). But in subsequent runs one shall see different (increased) IDs.

Run the example

docker-compose run example

(There may be delays in waiting for the hausra-server to be up running)

Run it again (note the DB or hasura-server were not restarted):

docker-compose run example

(Note that although the same fixtures are created, IDs are different)
