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 🙏

//方式二 推荐,避免全局加载
var storage = require('beyond-lib/lib/storage')

typescript 方式

//方式一

import * as storage from 'beyond-lib/lib/storage'

dateDiff.years(new Date(2008,01,01),new Date(2006,02,01))  // return 2
dateDiff.years(1170259200000,1141142400000)  // return 1
dateDiff.years(new Date(2006,01,01),new Date(2008,02,01))  // return -2
dateDiff.years(+new Date(2007,01,01),new Date(2007,02,01))  // return 0
dateDiff.years(+new Date(2007,01,01),new Date(2007,02,01))  // return 0

dateDiff.months(date1,date2)
dateDiff.months(timestamp1,timestamp2)
dateDiff.months(date1,timestamp2)

dateDiff.days(date1,date2)
dateDiff.hours(date1,date2)
dateDiff.minutes(date1,date2)
dateDiff.seconds(date1,date2)

dateFormat

返回格式化后的日期时间字符串

import dateFormat from 'beyond-lib/lib/dateFormat'
dateFormat(new Date(2000,00,01,12,12),'yyyy-MM-dd')  // 返回该时间戳的默认日期 2000.01.01

| 类型 | 说明 |
| -----| ----- | | yyyy | 4位数年份 |
| yy | 2位数年份 | | MM | 2位数月份,如果是个位则前置0 |
| M | 月份 |
| dd | 2位数日期,不足前置0 |
| d | 日期 |
| HH | 2位数24制小时,不足2位前置0 | | H | 24制小时 | | hh | 2位数12制小时,不足2位前置0 | | h | 12制小时 |
| mm | 2位数分钟,不足前置0 | | m | 分钟 |
| ss | 2位数秒,不足前置0 | | s | 秒 |
| S | 毫秒 |
| u | 星期几,0-6,0表示周日 |

htmlHelper

import htmlHelper from 'beyond-lib/lib/htmlHelper'
htmlHelper.encodeHTML('<a href="#">hello&\'quote\'</a>')
htmlHelper.decodeHTML('&lt;a href=&quot;#&quot;&gt;hello&amp;&#039;quote&#039;&lt;/a&gt;')

storage

浏览器本地存储,包括 localStorage 和 cookie

import * as storage from 'beyond-lib/lib/storage'
//localstorage
storage.set('key',{value : 'value'})
storage.get('key')

//cookie,expire 单位为天
storage.setCookie('key','value')
storage.setCookie('key','value',expire,path,domain,secure)
storage.setRawCookie('key','value')
storage.setRawCookie('key','value',expire,path,domain,secure)
storage.getCookie('key')
storage.getRawCookie('key')

url

url解析

import {parseUrl} from 'beyond-lib/lib/url'

var info = parse('http://rob:[email protected]:9090/path/index.html?query1=test&silly=willy#test=hash&chucky=cheese')
info.protocol   // http
info.auth       // rob:abcd1234
info.user 		// rob
info.pass 		// abcd1234
info.host 		// 1.2.3.4:9090
info.port  		// 9090
info.hostname   // 1.2.3.4
info.hash  		// test=hash&chucky=cheese

EventBus

自定义事件,事件派发

import EventBus from 'beyond-lib/lib/EventBus'
var e = EventBus

//绑定事件
let off = e.on('load',function(event){
	console.log('loaded')
	console.log(event.data)
})

//触发事件
e.trigger('load',data)


//解除绑定
off()

lock & delay

节流 和 防抖

// 节流
import lock from 'beyond-lib/lib/lock'
// 防抖
import delay from 'beyond-lib/lib/delay'

let fn = ()=> console.log('abc')

let lockFn = lock(fn,0.3)  
let delayFn = lock(fn,0.3)  

createStore & createProxy

缓存 remoter 接口和变更 remoter 接口返回,与 beyond-remote 搭配食用更香

import createStore,{createProxy} from 'beyond-lib/lib/createStore'
let i = 0
var remoter = function(){
	return new Promise(function(resolve,reject){
		resolve({data : ++i})
	})
}
let remoterWithCache = createStore(remoter)
remoterWithCache().then((res)=> console.log(res.data))  // 1
remoterWithCache().then((res)=> console.log(res.data))	// 1

let j = 0
var remoter2 = function(){
	return new Promise(function(resolve,reject){
		resolve({data : ++j})
	})
}
let remoterWithCache2 = createStore(remoter2,(res)=> res.data  )
remoterWithCache().then((data)=> console.log(data)) // 1
remoterWithCache().then((data)=> console.log(data))	// 1

let k = 0
var remoter3 = function(){
	return new Promise(function(resolve,reject){
		resolve({data : ++k})
	})
}
//createProxy 单纯对接口调用做数据过滤,不做缓存
let remoterWithProxy = createProxy(remoter3,(res)=> res.data  )
remoterWithProxy().then((data)=> console.log(data)) // 1
setTimeout(()=>{
	remoterWithProxy().then((data)=> console.log(data))	// 2
},1000)
