graphql - 带有 Apollo 的 Graphql - 重构查询，返回对象重复（差异查询中的相同字段）

Question

我有几个具有相同返回类型的查询：

// Query 1
gql`
        mutation insert_shops_users($shopId: uuid) {
          insert_shops_users(objects: [{ shopId: $shopId }]) {
            affected_rows
            returning {
              Shop {
                id
                users {
                  userId
                }
              }
            }
          }
        }
      `,

// Query 2
gql`
        mutation delete_shops_users_by_pk($shopId: uuid!, $userId: String!) {
          delete_shops_users_by_pk(shopId: $shopId, userId: $userId) {
            Shop {
              id
              users {
                userId
              }
            }
          }
        }
      `,

现在，我想提取这部分，例如在名称下ShopUserResult并在两个查询中使用它：

在 ShopUserResult 下提取

Shop {
  id
  users {
    userId
  }
}

结果查询

// Query 1 - after refactor
gql`
        mutation insert_shops_users($shopId: uuid) {
          insert_shops_users(objects: [{ shopId: $shopId }]) {
            affected_rows
            returning {
             ShopUserResult
            }
          }
        }
      `,

// Query 2 - after refactor
gql`
        mutation delete_shops_users_by_pk($shopId: uuid!, $userId: String!) {
          delete_shops_users_by_pk(shopId: $shopId, userId: $userId) {
            ShopUserResult
          }
        }
      `,

我是graphql的新手，任何关于重构的建议都将不胜感激，谢谢。

Answer 1

可以使用片段（source 1，source 2）重构重复的字段集：

查询 - 之前

gql`
  mutation insert_shops_users($shopId: uuid) {
    insert_shops_users(objects: [{ shopId: $shopId }]) {
      affected_rows
      returning {
        Shop {
          id
          users {
            userId
          }
        }
      }
    }
  }
      `,

查询 - 使用片段后

分段

const ShopWithUsers = gql`
  fragment ShopWithUsers on shops {
    id
    users {
      userId
    }
  }
`

询问

gql: gql`
  mutation insert_shops_users($shopId: uuid) {
    insert_shops_users(objects: [{ shopId: $shopId }]) {
      affected_rows
      returning {
        Shop {
          ...ShopWithUsers
        }
      }
    }
  }
  ${ShopWithUsers}
`,
