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…

While certain fields in a GraphQL Schema can be optional, there are some fields or arguments that are necessary in order to either fulfill a query, or to provide a guarantee to people using the Schema that some field exists. In this video, we'll take…

Writing out a GraphQL Schema in the common GraphQL Language can work for simple GraphQL Schemas, but as our application grows, or when we start using more complex types like interfaces or unions, we find that we can’t use a GraphQL Language file in t…

If we have a GraphQL Schema expressed in terms of JavaScript, then we have a convenient package available to us that let’s us easily serve up our schema on any endpoint in an Express Server. In this video, we’ll use the express-graphql package to ser…

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');…

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…
