使用graphql-code-generator 生成graphql 代码

类似的工具比较多，比如prisma 、qloo、golang 的gqlgen、apollo-codegen
graphql-code-generator 也是一个不错的工具（灵活、模版自定义。。。）

安装

 npm install --save-dev graphql-code-generator graphql
 Or
 yarn add -D graphql-code-generator graphql

参考demo

• 项目初始化

yarn init -y 

• 添加依赖

 yarn add --dev graphql-code-generator graphql
package.json:

{
"name": "first",
"version": "1.0.0",
"main": "index.js",
"license": "MIT",
"devDependencies": {
"graphql": "^0.13.2",
"graphql-code-generator": "^0.10.7",
"graphql-codegen-typescript-template": "^0.10.7",
"typescript": "^3.0.1"
},
"scripts": {
"gen": "gql-gen --schema http://localhost:3009/graphql --template graphql-codegen-typescript-template --out ./typings/ "./src/**/*.graphql"",
"code":"tsc "
}
}
