Facebook GraphQL 协议的 Go 语言版本。相比之前的其它 GraphQL 库，通过反射结构体的 tag 可以自动生成 schema 给前端，更加便于开发。示例代码： ```go // Friend is a small struct representing a person. type Friend struct { FirstName string Last string `graphql:"lastName"` // use a custom name Added time.Date `graphql:"-"` // don't expose over graphql } // FullName builds a friend's full name. func (f *Friend) FullName() string { return fmt.Sprintf("%s %s", f.FirstName, f.Last) } // registerFriend registers custom resolvers on the Friend type. // // Note: registerFriend wouldn't be necessary if the type only // had the default struct field resolvers above. func registerFriend(schema *schemabuilder.Schema) { object := schema.Object("Friend", Friend{}) // fullName is a computed field on the Friend{} object. object.FieldFunc("fullName", Friend.FullName) } ```
