推荐答案

Socket.IO 是一个能够在浏览器和服务器之间进行实时、双向和基于事件的通信的库.socket.io

GraphQL 订阅另一方面是一个允许客户端收听来自服务器的实时消息的概念.

GraphQL Subscriptions on another hand is a concept that allows clients to listen to real-time messages from the server.

所以基本上，GraphQL 订阅 是一个定义政策和的规范.允许 GraphQL 客户端和服务器实时通信的规则.要实现该功能，您可以使用 Socket.io 等实时工具.

So basically, GraphQL Subscriptions is a specification that defines the policies & rules that allow GraphQL clients and servers to communicate in real-time. And to implement the feature, you can use real-time tools like Socket.io.
