dgraph_graphql_module

本项目是 graphql 的超简单部署和开发,从此绝大部分需求都可摆脱后端 curd,后端工作量大减,前端不用学后端就可成为全栈!!!

简介

本项目使用 dgraph 图数据库,摆脱了传统关系型数据库的联表查询等复杂的查询方式,直接以图结构的节点和边的模型来储存数据和表示数据之间的关系,适合快速开发一些小项目,大项目的话,由于还没有和传统的关系型数据库做一个同样接口下的 io 性能测试,所以还不清楚大项目中,高并发高读写情况下 dgraph 的数据库能力,不过据 dgraph 官方描述是非常棒的,尤其是在大表的联表查询的时候,图数据库是完爆关系型数据库的,有兴趣的朋友可以自行测试一下;

项目内容

本项目主要为使用 dgraph 图数据库的 graphql 语言提供一个简易的 todo-app 作为开发模板,包含了一个 go 语言写的 jwt 鉴权后端,和如何部署如何调试的文档,以及学习 dgraph 图数据库的 graphql 查询语言的语法的 md 文档,详细的 dgraph 图数据库的英文文档请移步dgraph doc

部署

  • clone 本项目

    git clone --recursive https://gitee.com/wisgon/dgraph_graphql_module.git

  • 安装 docker,安装完后,按照部署文档进行环境部署

  • 安装 nodejs,npm,这个前端必备技能,就不多说了,作者这边的 node 版本是 v10.19.0,npm 版本是 6.14.4,大家可酌情安装对应版本,不一定要完全一样,差不多就行

运行

  • 如果是宝塔部署的,则进入 dgraphql_backend/bin 文件夹下,选择对应平台的 main_baota 可执行文件,执行,如果是 docker 的 nginx 容器部署的,则在部署环节已经运行了对应的 main_nginx 了;
  • 运行前端:
    cd vue-todo-app
    npm install
    npm run serve
    访问localhost:8081即可看到 todo-app 的主页,然后点 Rigest 注册用户、登陆,之后就可尝试添加 todo 了; 至此,尽情体验不用写后端接口的畅快吧
    效果图: todo-app
    成功运行后,要先注册自己的帐号密码,然后注册名为peter和名为others的账号,密码随便,这样,才可以运行一些本项目的一些演示示例;

学习文档

接下来的计划

  • 添加用户彼此是 friend 的场景 demo,某个用户将 todo 变成 public,他的朋友可以看到
  • 添加 graphql 的 subscribe(相当于 websocket,当监听的数据变化了,客户端可获得实时推送)
  • 做数据库测试,测一下相同的 io 条件下 dgraph 和 mysql 的性能差异
  • jwt 的 token 过期后的处理
  • 更多不同需求场景相应的 demo
  • dgraph 天生支持分布式,写 dgraph 分布式 md 文档以及示例 demo
  • 保持 dgraph 官方文档和本项目文档的同步,在作者做这个项目的时候,dgraph 图数据库也是在发展中的,其 graphql 功能也是今年 2020 年初刚推出不久,很多功能也在开发中,作者会持续保持对 dgraph 数据库官方文档的跟进,保持更新
  • 多编程语言的 jwt 后台

谢谢大家的支持,如果觉得不错,不要忘记 star 和 fork 喔^_^
