gqlgen

  • 99designs/gqlgen 是什么?
    • 基于生成的 GraphQL 引擎
    • Schema first - 需要 DSL 定义 GraphQL Schema
    • 类型安全
    • 支持 Plugin - 修改配置, 生成代码
  • 缺点
    • 库代码质量一般
    • 文档少
    • 插件能力弱,且没什么 Demo
  • gqlgen vs gophers vs graphql-go vs thunder
    • gqlgen 最近开发不活跃 - 2021-08
    • graphql-go/graphql 开发不活跃
caution
go get -u github.com/99designs/gqlgen
go run github.com/99designs/gqlgen init

go run github.com/99designs/gqlgen generate

Note

type HandlerExtension interface {
// ExtensionName should be a CamelCase string version of the extension which may be shown in stats and logging.
ExtensionName() string
// Validate is called when adding an extension to the server, it allows validation against the servers schema.
Validate(schema ExecutableSchema) error

禁用 Introspection

srv.AroundOperations(func(ctx context.Context, next graphql.OperationHandler) graphql.ResponseHandler {
if !isUserAdmin(ctx) {
graphql.GetOperationContext(ctx).DisableIntrospection = true
}
return next(ctx)
})
