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 🙏

Readme

clone-rename

English

深拷贝你的对象并且重命名属性。

开始

> npm install clone-rename

何时试用

前后端分离的情况下,后端返回数据的属性名称和前端独立开发时使用的属性名称不一样。

例子

后端返回数据的属性名称是 idname 但是 mock 数据时前端使用的是 goodsIDgoodsName

拷贝数组

import cloneRename from 'clone-rename';

const res = [
    {
        id: '001',
        name: 'apple'
    },
    {
        id: '002',
        name: 'banana'
    }
]

const filter = {
    id:'goodsID', // 将所有属性为 id 的 key 更改为 goodsID 。
    name: 'goodsName' // 将所有属性为 name 的 key 更改为 goodsName 。
}

const result = cloneRename(res,filter) // 默认是深拷贝

/*
result:
[
    {
        goodsID: '001',
        goodsName: 'apple'
    },
    {
        goodsID: '002',
        goodsName: 'banana'
    }
]
*/

拷贝对象

它还能拷贝对象


import cloneRename from 'clone-rename';

let project = {name:'JavaScript'}

let obj = {
    name:'PsChina',
    age:'25',
    like:[project]
}

const filter = {
    name:'babel' // 将所有属性名为 name 的 key 改名为 babel 。
}

const result1 = cloneRename(obj,filter) // 第三个参数不传递默认是开始深拷贝和深度更改键名。{deepCopy:true, deepRename:true}
/*
result1:
{
    babel:'PsChina',
    age:'25',
    like:[{babel:'JavaScript'}]
}
*/
result1.like[0] === project // false

浅层拷贝

const result2 = cloneRename(obj,filter,{deepCopy:false})

/*
result2:
{
    babel:'PsChina',
    age:'25',
    like:[{name:'JavaScript'}]
}
*/

result2.like[0] === project // true

浅层重命名

const result3 = cloneRename(obj,filter,{deepRename:false})

/*
result3:
{
    babel:'PsChina',
    age:'25',
    like:[{name:'JavaScript'}]
}
*/
result3.like[0] === project // false

拷贝

它还能拷贝 date 对象和 function 以及正则表达式

拷贝日期对象

let time = new Date();

let sameTime = cloneRename(time);

console.log(time, sameTime ,time===sameTime);
// <currentTime> <currentTime> false

拷贝函数

function sum(a, b){
    return a + b;
};

let sameSum = cloneRename(sum);

sum(1,2);
//3

sameSum(1,2);
//3

console.log(sum === sameSum);
//false

拷贝正则表达式

let numberRegObj = {reg:/[0-9]/};

let newRegObj = cloneRename(numberRegObj);

console.log(numberRegObj, newRegObj, numberRegObj.reg === newRegObj.reg);
// {reg:/[0-9]/} {reg:/[0-9]/} false
