How to use

To send a query, you can use the following URL:

http://localhost:3000/graphql

You can use the following queries and mutations:

Use the following query to get the list of pets:
```
  {
    pets {
      name
      age
      ownerName
    }
  }
```
(Note that the fields between curly braces are the fields that you want to get from the query, in this case when you send the query, you will get the name, age and ownerName of each pet)

You can use the following query to get a pet by id:

  {
    pet(id: "pet_id") {
      id
      name
      age
    }
  }

You can use the following mutation to create a pet:
```
  mutation {
    create(name: "pet", age: 0, ownerName: "owner"){
      id
      name
      age
      ownerName
    }
  }
```
(To use a mutation, you need to use the keyword "mutation" and then the name of the mutation, in this case "create", and then you need to pass the parameters that the mutation needs, in this case name, age and ownerName)

You can use the following mutation to update a pet:

  mutation {
    update(id: "pet_id" ,name: "new name"){
      id
      name
      age
      ownerName
    }
  }

You can use the following mutation to delete a pet:
```
  mutation {
    delete(id: "pet_id")
  }
```
