react实战系列 —— 起步(mockjs、第一个模块、docusaurus)

react实战 系列

起步

本篇我们首先引入 mockjs ,然后进入 spug 系统,接着模仿”任务计划“模块实现一个类似的一级导航页面(”My任务计划“),最后玩一下 Facebook 的 docusaurus,将 spug 官网文档在本地跑起来。

Tip:环境准备请看 上文

mockjs

点击登录,提示“请求异常: Network Error”。因为没有后端提供接口。

笔者使用 mockjs 来绕过,进入系统。

添加 mockjs 只需要三步。

首先安装依赖:

spug-study> npm i -D mockjs@1

added 1 package, and audited 1789 packages in 54s

107 packages are looking for funding
  run `npm fund` for details

33 vulnerabilities (1 low, 16 moderate, 15 high, 1 critical)

To address issues that do not require attention, run:       
  npm audit fix

To address all issues (including breaking changes), run:    
  npm audit fix --force

Run `npm audit` for details.

然后新建 src/mock/index.js,内容如下:

import Mock from 'mockjs'

// 开发环境引入 mock
if (process.env.NODE_ENV === 'development') {
    Mock.mock('/api/account/login/', 'post', {
        "data": { "id": 1, "access_token": "5bb076db06fd4001b85d12e44ab96c56", "nickname": "\u7ba1\u7406\u5458", "is_supper": true, "has_real_ip": true, "permissions": [] }, "error": ""
    })
}

最后在 src/index.js 中引入 mock:

+ import './mock'

重启服务,再次点击点击“登录”,即可进入系统:

Tip:spug 提供了“演示预览”,只需要关注即可获取体验账号,上面的 mock 数据就是这么来的。

:mockjs 这种使用方式,在浏览器开发界面是看不到 ajax 请求的。倘若想看到 ajax 请求,你可以把 mockjs 配合 node 的 express 使用,mockjs 仅仅当作造数据的工具,url 匹配就交由 express 处理。

任务计划

”任务计划“页面分为两部分:上面用于过滤、下面是表格:

spug-study-mock4.png

My任务计划

模仿”任务计划“,最终效果如下:

spug-study-mock5.png

点击“开始执行”和刷新表格,“更新于“中的模拟时间都会变化。

代码如下:

新增导航”M任务计划“:

// src/routes.js
import ScheduleIndex from './pages/schedule';
+ import MyScheduleIndex from './pages/myschedule';

  {
    icon: <ScheduleOutlined/>,
    title: '任务计划',
    auth: 'schedule.schedule.view',
    path: '/schedule',
    component: ScheduleIndex
  },
+ {
+   icon: <ScheduleOutlined/>,
+   title: 'M任务计划',
+   auth: 'myschedule.myschedule.view',
+   path: '/myschedule',
+   component: MyScheduleIndex
+ },

增加 mock 数据:

// src/mock/index.js

// 开发环境引入 mock
if (process.env.NODE_ENV === 'development') {
   
    Mock.mock('/api/schedule/', 'get', {
        "data": { "types": ["每天执行"], "tasks": [{ "id": 1, "name": "\u6e05\u7406\u8ba2\u5355\u6570\u636e", "type": "\u6bcf\u5929\u6267\u884c", "command": "echo '\u6e05\u7406\u8ba2\u5355\u6570\u636e'", "targets": ["local"], "trigger": "cron", "trigger_args": { "rule": "0 1 * * *", "start": null, "stop": null }, "is_active": true, "desc": null, "latest_id": null, "rst_notify": { "mode": "0" }, "created_at": "2021-04-28 12:07:56", "created_by_id": 1, "updated_at": "2021-04-28 12:19:16", "updated_by_id": 1, "latest_status": null, "latest_run_time": null, "latest_status_alias": null }] }, "error": ""
    })

    Mock.mock('/api/myschedule/', 'get', () => ({
        "data": [{ "id": 1, "name": "项目A", machine: '192.168.1.3', time: new Date().toLocaleTimeString(), status: '进行中'}], 
        "error": ""
    }))

    // 点击“开始执行”
    Mock.mock(/\/api\/myschedule.*/, 'post', () => ({
        data: { test: 'test' }, error: ''
    }))
}

增加 myschedule 路由组件。共 3 个文件,内容如下:

// src/pages/myschedule/index.js

import React from 'react';
import { observer } from 'mobx-react';
import { Select, Button } from 'antd';
import { SearchForm, AuthDiv, Breadcrumb } from 'components';
import ComTable from './Table';
import store from './store';

export default observer(function () {
  return (
    <AuthDiv auth="myschedule.myschedule.view">
      <Breadcrumb>
        <Breadcrumb.Item>首页</Breadcrumb.Item>
        <Breadcrumb.Item>M任务计划</Breadcrumb.Item>
      </Breadcrumb>
      <SearchForm>
      <SearchForm.Item span={6} title="项目">
          <Select allowClear value={store.name} onChange={v => store.name = v} placeholder="请选择">
            <Select.Option value="p1">项目1</Select.Option>
            <Select.Option value="p2">项目2</Select.Option>
            <Select.Option value="p3">项目3</Select.Option>
            <Select.Option value='p4'>项目4</Select.Option>
          </Select>
        </SearchForm.Item>

        <SearchForm.Item span={6} title="机器">
          <Select allowClear value={store.machine} onChange={v => store.machine = v} placeholder="请选择">
            <Select.Option value='m1'>机器1</Select.Option>
            <Select.Option value='m2'>机器2</Select.Option>
            <Select.Option value='m3'>机器3</Select.Option>
            <Select.Option value='m4'>机器4</Select.Option>
          </Select>
        </SearchForm.Item>
        <Button type="primary" onClick={store.build}>开始执行</Button>
      </SearchForm>
      <ComTable />
    </AuthDiv>
  )
})
// src/pages/myschedule/store.js

 import { observable, computed } from 'mobx';
 import http from 'libs/http';
 
 class Store {
   // 表格数据
   @observable records = [];
   // 是否正在请求数据
   @observable isFetching = false;

   // 计算属性
   // 数据源
   @computed get dataSource() {
       return this.records
   }
 
   fetchRecords = () => {
     this.isFetching = true;
     http.get('/api/myschedule/')
       .then(res => this.records = res)
       .finally(() => this.isFetching = false)
   };

   build = () => {
    const params = {
      name: this.name,
      machine: this.machine
    }
    console.log('params', params)
    http.post('/api/myschedule', {params})
      .then(res => {
        this.fetchRecords()
      })
   }
 }
 
 export default new Store()
// src/pages/myschedule/Table.js

import React from 'react';
import { observer } from 'mobx-react';
import { Tag } from 'antd';
import { Action, TableCard } from 'components';
import store from './store';

@observer
class ComTable extends React.Component {
  componentDidMount() {
    store.fetchRecords()
  }

  colors = ['orange', 'green', 'red'];

  columns = [{
    title: '项目',
    dataIndex: 'name',
  }, {
    title: '机器',
    dataIndex: 'machine',
  }, {
    title: '更新于',
    dataIndex: 'time',
  }, {
    title: '最新状态',
    render: info => {
      return <Tag color="blue">{info.status}</Tag>
    },
  }, {
    title: '操作',
    width: 180,
    render: info => (
      <Action>
        <Action.Button disabled>详情</Action.Button>
      </Action>
    )
  }];

  render() {
    return (
      <TableCard
        // tKey 必须唯一?
        tKey="msi"
        rowKey="id"
        title="M任务列表"
        loading={store.isFetching}
        dataSource={store.dataSource}
        onReload={store.fetchRecords}

        pagination={{
          showSizeChanger: true,
          showLessItems: true,
          showTotal: total => `共 ${total} 条`,
          pageSizeOptions: ['10', '20', '50', '100']
        }}
        columns={this.columns} />
    )
  }
}

export default ComTable

docusaurus

spug 的官网文档采用 Facebook 的 docusaurus快速 构建 高效 的网站,专注处理 内容) 来构建的。

:docusaurus 官网提到系统要求是 node >= 14,笔者尝试用 node 14 编译 spug-docs,报各种错误,最后尝试 node 16,却成功了。

放大图片

spug 官网文档默认没有放大图片功能,如果图片太大,则导致图片看不清。

可以使用 docusaurus 自定义插件(https://www.docusaurus.cn/docs/using-plugins)中的plugin-image-zoom

给 spug 官网文档添加图片放大的代码如下(from github):

plugins: [
    'plugin-image-zoom'
],

Configure the plugin in docusaurus.config.js, like this:

themeConfig: {
    imageZoom: {
        // CSS selector to apply the plugin to, defaults to '.markdown img'
        selector: '.markdown img',
        // Optional medium-zoom options
        // see: https://www.npmjs.com/package/medium-zoom#options
        options: {
        margin: 24,
        background: '#BADA55',
        scrollOffset: 0,
        container: '#zoom-container',
        template: '#zoom-template',
        },
    },
},

Tip:plugin-image-zoom 里面使用的其实和博客园中的图片放大插件相同,都是 medium-zoom

spug 与内网

倘若你要在内网中使用 spug,你可能会遇到如下问题:

cnpm 导致压缩失败

node_modules 压缩拷贝,如果安装 spug 的依赖使用的是 cnpm i,可能会压缩失败(笔者尝试使用了各种压缩工具),可以改用 npm i

win7

如果你的环境是 win7,那么 node 最多只能安装 node 14 以下的版本,笔者使用 v13.14

node 12 是不能对 spug 项目进行构建的。
