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 🙏

  • formatDate

(data:(string|number),fmt:string?)=> string

将时间戳格式化为日期字符串

  • dateToStamp

(str:string,len:number=10?)=> number

将日期字符串转换为时间戳

  • deepClone

(source:object)=> object

深拷贝

  • sublen

(value:string,len:number=8?)=> string

字符串截取

  • fixedTo

(val:(string|number),len:number=4?)=> number

四舍五入保留n位小数

  • delayFn

(fn, delay, mustDelay)=> function


/**
 * 函数节流
 * @param fn 需要被节流的函数
 * @param delay 触发执行的时间间隔
 * @param mustDelay 必然触发执行的间隔时间
 * @returns {*}
 */
  • isFunction

(target:any)=> boolean

判断是不是函数

  • isPlainObject

(target:any)=> boolean

判断是不是字面量对象

  • mergeOptions

(l:plainObject,r:plainObject)=> plainObject

深度合并对象

  • compose

(...rest:Array)=> function

函数管道

  • curry

(function)=> function

柯里化函数工厂

  • urlEncode

(target:plainObject)=> string

转换对象为uri参数字符串

http

  • createFetch

(hof:function?)=> Fetch

fetch 工厂

  • applyMiddleware

(...middleware:Array?)=> (Fecth|any)

中间件加载器

http middlewares

  • log

日志中间件

  • methods

基础http方法中间件(会改变fetch的默认行为 生成一个 包含{get,post,del,put}方法的对象)

NOTE: 如果使用methods中间件,methods必须是applyMiddleware的第一个参数,因为methods会改变fetch的默认行为

  • filter

(errorHandler=()=>{}?,chain=(response)=>{/.../}?)=> middleware

errorHandler:error=>void 错误处理方法

chain:response=>Promise 自定义数据处理

  • headers

(headers:plainObject)=>middleware

设置headers

demo

// base
const fetch = createFetch();

// advanced
const fetch = createFetch(applyMiddleware(methods,filter(),log));

math

math.strip(0.09999999999999998); // = 0.1
math.plus(0.1, 0.2);             // = 0.3, not 0.30000000000000004
math.plus(2.3, 2.4);             // = 4.7, not 4.699999999999999
math.minus(1.0, 0.9);            // = 0.1, not 0.09999999999999998
