Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

数据中台前端公共模块

hc-micro-common前端公共模块,提供数据中台各应用公共功能。

项目结构

| -- dist //打包后的目标文件夹
| -- lib
      | -- config //配置文件
      | -- core //核心工具方法,采用默认导出
         | -- baseApi.ts // 各个微服务在网关的baseApi
         | -- is.ts // 提供基础的类型判断方法
         | -- verify.ts // 提供emial,url,mobile,verifycode等校验方法
      | core-types //对core中方法的类型统一说明
      | -- directives // vue2方式自定义指令。提供copy,debounce,throttle,watermarker指令
      | -- page //预留的公共组件。
      | -- plugins //预留的第三方集成应用配置,如dayjs
      | -- request //统一的axios封装
      | -- styles //预留的公共样式
      | -- tools //模块开发工具类
      | -- utils // 其他工具类
      | -- index.ts //入口文件

安装使用

npm install hc-micro-common@latest --save

如何添加工具类

请把工具类放在 core 或者 utils下。约定core下放基础的工具方法,且默认导出,方便使用默认导入。utils中放特定的工具类。如notification。倒出时以对象方式导出。表示是特定的工具方法。

如何发布/更新模块

  1. 修改代码并测试通过提交

  2. 更新版本

    版本更新依据 语义化版本规范

    常用:

    npm version patch # 补丁。 效果:1.0.0  --> 1.0.1
    npm version minor # 小版本 效果:1.0.0  --> 1.1.0
    npm version major # 大版本 效果:1.0.0  --> 2.0.0
  3. 构建与发布

    npm run build # 构建代码  ts -> js
    npm publish # 发布到仓库

使用示例

http请求

具体请求方法约定放在@/api目录下

import { hcRequest as request, BaseApi, HcResponseData } from 'hc-micro-common'
import { QUERY_TYPE, TB_FD_TYPE, BUSINESS_TYPE } from '@/api/constant'

const Api = {
  database: '/dbs', // datasource crud operation
}

/**
 * 添加数据源
 * @param {{businessType: number}} params 业务类型
 * @param {import('../reqTypes').AddDsDTO} data 数据源信息
 * @returns {Promise<HcResponseData<import("../resTypes").DsVo>>} 数据源完整信息
 */
export function addDataSource(params, data) {
  return request({
    url: BaseApi.HCMETA_API + Api.database,
    method: 'post',
    params,
    data,
  })
}

使用定义的方法

在hc-micro-common中请求封装对业务错误(retCode不为0)也作为异常抛出。

add(params, data) {
    addDataSource(params, data).then((res) => {
        notification.success(res.retCode, '添加成功')
        this.$emit('done', this.type, res.data)
        this.form.resetFields()
    }).catch((error) => {
        notification.error(error.retCode, error.retMsg)
    })
},

async add(params, data) {
    try {
        const res = await addDataSource(params, data)
        notification.success(res.retCode, '添加成功')
        this.$emit('done', this.type, res.data)
        this.form.resetFields()
    } catch (error) {
        notification.error(error.retCode, error.retMsg)
    }
},

通用notification

import { hcNotification as notification } from 'hc-micro-common'

notification.error(error.retCode, error.retMsg)
notification.error(error) //同上一行代码

自定义指令

version <= 1.0.19

// 全局注册指令。包含copy,debounce,throttle等
import { hcDirectives } from 'hc-micro-common'
Vue.use(hcDirectives)
<a-button v-copy="'复制文本xxx'">测试copy</a-button>
<div
    style="width: 300px; height: 300px"
    v-waterMarker="{ text: 'xxx', textColor: 'red' }"
>
    测试waterMarker
</div>

<a-button
    type="primary"
    v-debounce="{
    callback: () => debounceClick(),
    time: 4000,
    }"
>
    测试防抖
</a-button>
<a-button
    type="primary"
    v-throttle="{
    callback: () => throttleClick(),
    time: 4000,
    }"
>
    测试节流
</a-button>

version >= 1.0.20新版本去除了自定义指令的注册。用户可自行注册:

import { vue2_directives} from 'hc-micro-common'
vue2_directives.copy
vue2_directives.debounce
...

日期格式化

| 方法名 | 功能 | 结果示例 | | -------------- | -------------- | ----------------- | | format2Day | 格式化到天 | 2022-01-27 星期四 | | format2Minute | 格式化到分 | 2022-01-27 09:16 | | formatRelative | 格式化相对时间 | 2 天前 |

以上方法是基于dayjs做的封装。使用者也可以直接引入dayjs使用其自带的方法。

import {
  format2Day,
  format2Minute,
  formatRelative,
  dayjs,
} from 'hc-micro-common'
console.log('day', format2Day(Date.now()))
console.log('min', format2Minute(Date.now()))
console.log('rel', formatRelative(new Date('2022-01-25')))

可能你想把这些方法用于模板渲染,可把方法注册到filters中,作为过滤器使用。

import { formatRelative } from 'hc-micro-common'

filters: {
    formatRelative,
}
<div>
    {{ new Date('2022-01-25') | formatRelative }}
</div>

屏幕媒体查询

主要用于页面响应式显示。比如表格在不同屏幕下的拉伸效果。

import { enquireNoteBookScreen } from 'hc-micro-common'

mounted() {
    //根据屏幕宽度 动态设置表格出于可拉伸模式or滚动模式
    enquireNoteBookScreen((isNoteBook) => {
      this.changeMode(isNoteBook)
    })
  },
  methods: {
    changeMode(isNoteBook) {
      if (isNoteBook) {
        this.tableComponents = {}
        this.scroll = { x: 1500 }
      } else {
        this.scroll = undefined
        this.tableComponents = genComponents(this.columns)
      }
      this.key++
    },
  }

使用公共插件

dayjs

import { dayjs } from 'hc-micro-common'

日期格式化无法处理的,可使用dayjs原生处理

axios

import { axios } from 'hc-micro-common'

可基于axios做封装

使用Jest测试

因项目使用TypeScript开发, 因此使用ts-jest执行jest测试.

#执行所有测试
npm test
# 执行单个文件测试
npx jest ./test/utils/HierarchyUtils.test.ts
