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 🙏

utils94(工具类函数集结)

| 工具类 | 功能 | | ---------- | --------------------- | | WeChat | 微信端jssdk处理 | | dom | dom 相关 | | bom | bom 相关 | | date | 时间相关(日历生成) | | feature | 功能 | | storage | 缓存 | | platform | 平台判断 |

快速使用

yarn add utils94 

import Utils from 'utils94'

import { WeChat, dom, bom... } from 'utils94'

1. WeChat

  • new WeChat(WeChatJsSdk, [{title,desc,link,imgUrl},{title,link,imgUrl}], requset) 初始化

    import {WeChat} from 'utils94' 
      
    // 朋友,QQ分享内容
    const friendShareConfig = {
      title: '微信分享title',
      desc: '详细',
      link: window.location.href,
      imgUrl:''
    }
    // 朋友圈,QQ空间分享内容
    const momentShareConfig = {
      title: '', // 分享标题
      link: '', // 分享链接,该链接域名或路径必须与当前页面对应的公众号JS安全域名一致
      imgUrl: '', // 分享图标
    }
      
    const request =async (body) => {
      /** 
        * !划重点!!!!
        * ios中,url 必须是初次进入的url. 且ios 仅需配置一次即可.
        * android中, 需要每次进入新的页面都需要配置一次. 每次配置
        * url 需要过滤 #及之后的参数
      **/
      const {url, jsApiList} = body
      const config = await api.initJsSdk(body)
      /**  config:{
            debug?: boolean; // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打印。
            appId: string | number; // 必填,公众号的唯一标识
            timestamp: number | string ; // 必填,生成签名的时间戳
            nonceStr: string; // 必填,生成签名的随机串
            signature: string;// 必填,签名
            jsApiList: string[] // 必填,需要使用的JS接口列表 
          }
      **/
      return config
    }
      
    // 初始化配置(必须)
    const wx = new WeChat(
      WxChatJsSdk, // 微信js 
      [
        friendShareConfig,
        momentShareConfig
      ],
      request
    )
  • pre 前置预检,

  • 返回Promise

    wx.pre().then(res => {
      // 配置成功
      // dosomething
    }).catch(err=>{
      // 配置失败
    })
  • share( [{title,desc,link,imgUrl},{title,link,imgUrl}], filter:string[]) 分享设置,filter可过滤掉link上携带的query字段,如‘token’;

  • 无返回

    wx.pre().then(()=> {
      // 当momentShareConfig 不传时,默认 friendShareConfig 替代
      wx.share([friendShareConfig, momentShareConfig], ['token'])
    })
  • autoShare( [{title,desc,link,imgUrl},{title,link,imgUrl}], filter:string[]) 自动分享设置,filter可过滤掉link上携带的query字段,如‘token’;

  • 返回Promise

    // 当momentShareConfig 不传时,默认 friendShareConfig 替代
    wx.autoShare([friendShareConfig, momentShareConfig], ['token']).then(()=> {
      // dosomething
    })

2. dom

  • on(element, event, function, object | boolean) 事件监听

  • 返回 监听函数

    关于passive 的情况,点击了解

    import { dom } from 'utils94'
    // ! 自动检查并开启passive 优化
      
    // 事件监听
    dom.on(
      window, 
      'scroll', 
      e => { /* dosomething */},
      {
        capture: false, // boolean 表示 listener 会在该类型的事件捕获阶段传播到该 EventTarget 时触发。
        once: false,   // boolean 表示 listener 在添加之后最多只调用一次。如果是 true, listener 会在其被调用之后自动移除。
        passive: true  // boolean 设置为true时,表示 listener 永远不会调用 preventDefault()。如果 listener 仍然调用了这个函数,客户端将会忽略它并抛出一个控制台警告。
      }
    )
      
    dom.on(
     window,
      'scroll',
      e => { /* dosomething */},
     false  // false: 冒泡 默认; true:捕获
    )
      
  • off(element, event, function, object | boolean) 移除事件监听

  • 返回 移除监听函数

    import { dom } from 'utils94'
      
    // 移除事件监听
    dom.off(
     window,
      'scroll',
      e => { /* dosomething */},
      {
        capture: false, 
        once: false, 
        passive: true
      }
    )
      
    dom.off(
     window,
      'scroll',
      e => { /* dosomething */},
     false
    )

3. bom

  • copy(text:string) 复制dom中的文字

  • 返回 boolean,true 成功;false 失败

4. date

  • createMonth(date?:Date | string | number = Date.now(),weekStart?: number = 1 ) 不传默认当前机器时间月份, weekStart: 1 默认周一开始

  • 返回二维对象数组,以周为单位分割

    import { date } from 'utils94'
    const arr = date.createMonth()
    /* 返回 
    [
      [
        {
          "date": "2020-12-27T16:00:00.000Z",  // Date 对象
          "data": {               // 数据
            "day": "2020/12/28",        // 当前日期
            "week": 1,             // 周几 
            "current": false          // 是否为当前月数据
          }
        }
        ...
      ],
      ...
    ]
    */

import { LocalStorage, SessionStorage, CookieStorage } from 'utils94/storage'
LocalStorage.set('test', {a:1})  // test '{"a":1}'
LocalStorage.get('test' )  // {a: 1}
LocalStorage.remove('test') // void
LocalStorage.clear() // void

// 其他两个同上使用,只不过CookieStorage 支持传递配置项,且没有clear函数
