do some mutations & queries (here with httpie against the POST endpoint)

echo '{
  "query": "mutation Foo($draft: ProductInput!) { createProduct(productDraft: $draft) { id name description } }",
  "variables": {
    "draft": {
      "name": "Tenet - BluRay",
      "description": "sator arepo tenet opera rotas"
    }
  }
}' | http -f POST :8080/graphql

Query Products

echo '{ "query" : "query { products { name id } }" }' | http -f POST :8080/graphql

    "draft": {
      "name": "Tenet - BluRay",
