graphql-modules-validate

Secondary encapsulation based on GraphQL-modules.。

As our project gets bigger and bigger, graphQL gets bigger and bigger, and we need to modularize them in a way that helps decouple and maintain them.

installation

npm i --save graphql-modules-validate
or
yarn add graphql-modules-validate

Modular use method：

For example, we can divide it into several modules

User module GraphQL

Suppose we have two modules: the user and marketing modules

The directory structure

user
marketing

User directory structure

  user
     index.js
     module.js

Index.js in the user module

   import { UserModule } from './module';

    export default [UserModule];

graphql-modules-validate How do you verify that?

First, let's introduce the user and marketing modules we just introduced

Then I'll introduce graphqL-modules-validate

Used in HTTP：

基于graphql-modules二次封装。

当我们的项目越来越大的时候，graphql就会越来越大，这个时候我们需要把他们模块化，这样方式可以利于解耦和维护。

安装

npm i --save graphql-modules-validate
or
yarn add graphql-modules-validate

模块化使用方法：

比如 我们可以分为几个模块

用户模块 graphql

假如我们有 两个模块一个是 user和 marketing 模块

目录结构

user
marketing

user目录结构

  user
     index.js
     module.js

user 模块中的index.js

   import { UserModule } from './module';

    export default [UserModule];

graphql-modules-validate 是如何做验证的呢？

首先我们将刚才的 user和marketing模块引入进来

然后在把graphql-modules-validate引入

在http中使用：
