We can create the most basic components of our GraphQL Schema using GraphQL's Object Types. These types allow us to group related fields together under a specific type, such as a Video or a User, and then allows us to fetch these types when we query…

When we have certain mutations that require more complex input parameters, we can leverage the Input Object Type in GraphQL. In this video, we’ll learn how to create an Input Object Type and how to add it to a GraphQL Mutation Type. const express = r…

本文章是介绍和记录如何创建GraphQL项目,以及如何使用GraphQL进行数据的相关操作.项目参照GraphQL .Net 的官方文档进行实践 一.项目结构: 为了更好的和原有的项目结合在一起,尽可能减少对原项目的修改.我对项目结构做了如下分层. 二.项目结构分层说明 Contracts层: 项目的接口层,重点存放项目的一些接口.和原项目的分层结构的Contracts一致 Entities层: 实体模型层,存放实体模型.与原有项目的分层结构Entites层一致 GraphQLDemo: 是使用…

众所周知RESTful API是目前最流行的软件架构风格之一,它主要用于客户端和服务器交互类的软件.基于这个风格设计的软件可以更简洁,更有层次,更易于实现缓存等机制. RESTful的优越性是毋庸置疑的,不过GraphQL也可以作为一种补充,让你的服务既支持RESTful的http调用,也容许客户端通过GraphQL支持的声明式语法调用服务. 本篇文章并不想对比RESTful和GraphQL孰轻孰重,或者那种方式更好,相关比较可以参考GraphQL的前世今生.本文旨在介绍如何在ASP.NET C…

Interfaces are similar to Unions in that they provide a mechanism for dealing with different types of data. However, an interface is more suited for data types that include many of the same fields. In this lesson, we will query different types of pet…

Fragments are selection sets that can be used across multiple queries. They allow you to refactor redundant selection sets, and they are essential when querying unions or interface types. In this lesson, we will improve our query logic by creating a…
