graphql cli 开发graphql api flow

作用

• 代码生成

• schema 处理

• 脚手架应用创建

• 项目管理

安装cli

npm install -g graphql-cli

初始化项目（使用.graphqlconfig管理）

以下为demo

• demo 项目创建

graphql init

• 添加数据操作（一般名称为database）

使用prisma cli

prisma init database

• 添加database 项目

graphql add-project database

• 修改配置

.graphqlconfig.yaml

 projects:
  demo:
    schemaPath: schema.graphql
    extensions:
      endpoints:
        default: 'http://localhost:4466'
  database:
    schemaPath: src/generated/prisma.graphql
    extensions:
      prisma: database/prisma.yml

• 生成schema

graphql get-schema --project database

• 代码生成

  • 生成typescript typings

  .graphqlconfig.yaml

  
  projects:
    demo:
      schemaPath: src/schema.graphql
      extensions:
        endpoints:
          default: 'http://localhost:4466'
        codegen: 
          generator: typegen
          language: typescript
          input: "{binding,prisma}/*.ts"
          output:
            typings: src/typings.ts
    database:
      schemaPath: src/generated/prisma.graphql
      extensions:
        prisma: database/prisma.yml
  
  graphql codegen
  
  

  • 生成type 定义

  修改配置

  projects:
  demo:
    schemaPath: src/schema.graphql
    extensions:
      endpoints:
        default: 'http://localhost:4466'
      codegen: 
        generator: prisma-binding
        language: typescript
        output:
          binding: src/prisma.ts
  database:
    schemaPath: src/generated/prisma.graphql
    extensions:
      prisma: database/prisma.yml
  
  graphql codegen
  
  

  • binding

  修改配置

  install binding:
  npm install -g graphql-binding
  
  projects:
  demo:
    schemaPath: src/schema.graphql
    extensions:
      endpoints:
        default: 'http://localhost:4466'
      codegen:
        - generator: graphql-binding
          language: typescript
          input: schema.js
          output:
            binding: mybinding.ts
  database:
    schemaPath: src/generated/prisma.graphql
    extensions:
      prisma: database/prisma.yml
  
  graphql codegen
