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…

In order to handle collections of items in a GraphQL Schema, GraphQL has a List Type. In this video, we’ll learn the syntax for specifying a List of items in a GraphQL Schema. Quey list of videos: const { graphql, buildSchema } = require('graphql');…

A GraphQL fragment encapsulates a collection of fields that can be included in queries. In this video, we'll look at how to create fragments on types to reduce the amount of typing that needs to occur as queries become more complex. We'll use the Git…

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…

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…

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…

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…

我们知道 GraphQL 使用 Schema 来描述数据,并通过制定和实现 GraphQL 规范 定义了支持 Schema 查询的 DSQL (Domain Specific Query Language,领域特定查询语言).Schema 帮助将复杂的业务模型数据抽象拆分成细粒度的基础数据结构,而 DSQL 的实现则赋予了前端开发者自由组织和定制请求数据的能力.如果以一张图来表示的话,可以将 GraphQL 看做一条以 通用基础业务数据模型 为基础.将传统后端服务和前端页面紧密且自由地联系在一起…

https://kadira.io/blog/graphql/initial-impression-on-relay-and-graphql http://graphql.org/blog/subscriptions-in-graphql-and-relay/ Facebook recently made GraphQL and Relay open source, so now we can try them out. These are the two main components in…

文章转自 prisma 官方博客,写的很不错 In this article, we want to understand how we can use any existing GraphQL API and expose it through our own server. In that setup, our server simply forwards the GraphQL queries and mutations it receives to the underlying Grap…
