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 🙏

commonality

项目开发中通用到的工具类

安装

npm install @flyer/commonality || yarn add @flyer/commonality

广播器(消息订阅)

  1. 订阅广播 subscribe:(channel: string, commit: Function):void
  2. 广播消息 publish: (channel:string,data:Object):void
  3. 取消订阅广播 unsubscribe: (channel: string):boolean

实例方法

import {broadcaster} from '@flyer-ui/commonality'
const broadcaster = Broadcaster()
broadcaster.subscribe('114',(data)=>{
    log('收到广播回来的数据114-1',data)
})
broadcaster.subscribe('114',(data)=>{
    log('收到广播回来的数据114-2',data)
})
broadcaster.publish('114','data')
broadcaster.unsubscribe('114')

Debug

  1. warn 参数name:标记名称,msg:提示信息
  2. log 参数name:标记名称,msg:提示信息
  3. error 参数name:标记名称,msg:提示信息
  4. config 配置信息:moduleName:提示中模块的名称,默认为flyer-ui

Debug 使用方法

import {warn,log,error,config} from '@flyer-ui/commonality'
config.moduleName='module'

warn('name','msg',{other:'other'}) //[date][module.name] msg {other:'other'}
warn('name','msg') //[date][module.name] msg
warn('msg') //[date][module] msg

log('name','msg','other') //[date][module.name] msg other
log('name','msg') //[date][module.name] msg
log('msg') //[date][module] msg

error('name','msg',new Error('发生了未知错误')) //[date][module.name] msg ErrorInfo
error('name','msg') //[date][module.name] msg
error('msg') //[date][module] msg

精度计算

| 方法名称 | 说明 | 参数 | 返回值 | | -------- | ------- | ------- | --------------------------------- | | preciseAddition |数值精确添加的方法|num1:number, num2:number|number| | preciseReduce |数值精确减数的方法|num1:number, num2:number|number|

使用方法

import {preciseAddition,preciseReduce} from '@flyer-ui/commonality'
preciseAddition(0.1+0.2) // 0.3
preciseAddition(0.7,0.1) // 0.8
preciseReduce(1.5,1.2)   // 0.3
preciseReduce(0.3,0.2)   // 0.1

常用方法

  1. 格式化字占位符,例如:”{1},{2}“ format(...rest: Array<any>): string | undefined

  2. 将数字进行货币格式化 formatCurrency(value: string | number, unit: string = '¥'):string

  3. 可以生成并返回一个随机数的函数 randomNumber():number

  4. 判断是否是 string 对象 isString(obj: any): Boolean

  5. 深拷贝对象 deepClone(target:any):object >0.1.3有效

  6. 确保只执行一次函数 function once(fn: Function): Function

  7. 混合对象里的属性到指定的对象上 extend(to: object, _from: object): object

  8. 检测对象里是否包含有指定属性 hasOwn(obj: object, key: string | number | symbol): boolean

  9. 判断对象是否是纯粹的对象类型 isPlainObject(obj: object): boolean

  10. 执行一个空操作 noop(...rest: [any]): void

使用方法

import {
    isPlainObject,
    hasOwn,
    extend,
    deepClone,
    once,
    ~~debounce,~~
    isString,
    format,
    formatCurrency
} from '@flyer-ui/commonality'
// 或者直接引用全部
// import common from '@flyer-ui/commonality'
// common.format()

isPlainObject([]) // false
hasOwn({a:1},'a') // true
extend({a:1},{b:2}) // {a:1,b:2}
const result = {} 
deepClone(result,{
    b:2,
    c:{
        c1:'2.1',
        c2:'2.2'
    },
    a:1,
    e:[1,2,3,4]
})  // {"b":2,"c":{"c1":"2.1","c2":"2.2"},"a":1,"e":[1,2,3,4]}
let counter = 0
const fn = once((a:number,b:number)=>{
    log('我只执行了一次。')
    counter += (a + b)
})
fn(1,2) // 3
fn(1,2) // 3

const arry = [1,2,3,4]
arry.forEach(()=>{fn(1,2)}) //[23:11:44][Flyer-UI] debounce 我只执行了一次。0

isString({}) // false
format('{1},{2}','a','b') //a,b
formatCurrency(123456789.5) // ¥ 123,456,789.50

日期格式化

type TDate = {
  years: string | number
  months: string | number
  days: string | number
  hours: string | number
  minutes: string | number
  seconds: string | number
}
  1. 格式化日期,format是格式化的格式,date是要格式化的日期
formatDate(
  format: string,
  data: Date | string | number | TDate
):Date | string | number | TDate
  1. 根据参数返回年月日时分秒对象,为空则返回当前时间 getDate(param: string | number | Date): TDate
  2. 格式化日期,format是格式化的格式,date是要格式化的日期
formatDate(
  format: string,
  data: Date | string | number | TDate
):Date | string | number | TDate
  1. 填充时间,判断时间是否是十位数,不是则前位补0 fullTime(time: string | number): string
  2. 获取两个时是的间隔,返回年月日时分秒 getDiffTime(start?: string | Date, end?: string | Date,diffTime:number = 0): TDate
  3. 获取时间差并指定显示的位数,参数num值设置了后,template模块字符串要从年到秒填全。
getDiffTimeDescription(
  start?: string | Date,
  end?: string | Date,
  diffTime:number = 0,
  num?: number,
  template?: string
): string | undefined

使用方法

import {
  fullTime,
  getDate,
  formatDate,
  TDate,
  getDiffTime,
  getDiffTimeDescription
} from '@flyer-ui/commonality'

fullTime(0) // 00
getDate('2020-07-10') // {years: 2020,months: 7,days: 10,hours: 8,minutes: 0,seconds: 0}
formatDate('yyyy-MM-dd','2020-08-02') // 2020-08-02
getDiffTime('1986-07-03 15:03:23','2020-08-03 18:02:01') 
// { years: 34, months: 1, days: 1, hours: 3, minutes: 58, seconds: 38 }
getDiffTimeDescription('1986-07-03 15:03:23','2020-08-03 18:02:01')
//34年1个月1日3小时58分38秒

loader加载器

  1. 可动态加载JS/CSS的加载器 function loader(paths: string | Array<string>, callback: Function):void

使用方法

loader('https://unpkg.com/flyer-ui/lib/index.js',()=>{
    log('动态加载成功。。。')
})
