在 GraphQL 中，Relay 是一个用于构建现代 web 应用程序的库，它帮助开发人员管理客户端与服务器之间的数据交互，特别是处理分页、数据缓存和高效查询等问题。而 Relay types 主要与 Relay 的规范和操作相关，下面是一些常见的 Relay types： Global Object Identification (全球唯一标识符)： 在 Relay 中，所有对象都有一个全球唯一标识符（ID）。这是为了确保可以通过 id 属性唯一地标识每一个对象。Relay 使用 Node 类型的接口来支持这一特性。 这种做法可以保证客户端在处理数据时，能通过统一的标识符找到对象。 Connection： Relay 支持分页查询，它使用 Connection 类型来实现分页功能。Connection 类型包括一个 edges 数组和一个 pageInfo 对象。edges 数组包含查询结果的具体数据，而 pageInfo 则提供分页信息，如当前页是否还有更多数据。 在分页查询时，Relay 使用 first、last、before、after 等参数来限制和过滤数据。 Edge： 在 Relay 的分页查询中，Edge 表示连接中的单个节点，通常会包含数据本身以及分页的游标（cursor）。通过 cursor，客户端能够追踪到数据的顺序并实现分页。 Node： Node 类型是 Relay 的核心，表示一个可以通过 id…
