Mutation

GraphQL mutations are used to modify data on the server (i.e. write, update or delete data).

Mutations for the entire codebase resides in the file /app/shared/mutations/ts

The syntax for writing mutation is

  mutation <MUTATION_NAME>($objects: [<TABLE_NAME>_<TYPE_OF_OPERATION>_input!]!) {
    insert_user(objects: $objects) {
      affected_rows
      returning {
        <COLUMN_NAMES>
      }
    }
  }

Insert Mutation

  mutation insert_user($objects: [user_insert_input!]!) {
    insert_user(objects: $objects) {
      affected_rows
      returning {
		id
      }
    }
  }

Update Mutation

  mutation update_user($objects: user_set_input!) {
    update_user(
		where: {id: {_eq: 5}}
		_set: $objects) {
      affected_rows
      returning {
		id
      }
    }
  }
