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 🙏

安装

第一步,改变我们的源,

npm i -g nrm   
nrm add xgnpm http://172.16.1.194:4873/    
nrm use xgnpm;

第二步,安装包,

npm i @xinguang/common-tool --save-dev;     

第三步,在我们需要的地方引入包,就可以直接用了。

// 首先,引入工具包
import { DateUtil } from '@xinguang/common-tool'

// 比如上边引用的是DateUtil;在下边就可以直接引用DateUtil了。
let timeFormat = DateUtil.formatDate(1234567899875);
console.log(DateUtil)
console.log(timeFormat)

// 输出以下东西
function DateUtil() {
    _classCallCheck(this, DateUtil);
}

使用

这个包主要说的是一些常用的工具类,比如:


时间工具

====== 1. formatDate ======

将各种类型的值转变成我们需要的格式。

// 例一
let timeFormat =  formatDate(10000,"HH:mm:ss");// 数值会当成时间戳来计算

timeFormat // 08:00:10
// 按照1970-01-01 08:00:00 来算的

// 例二
let timeFormat =  DateUtil.formatDate(new Date());// 数值会当成时间戳来计算

timeFormat // 2017-07-27 17:48:58
// 这个随着时间的改变而改变

数组工具

数组操作工具类目前分为几个函数:

====== 1. isArray ======

判断我们输入的参数是不是一个数组。是的话返回true,否则为false。

let arr = [1,2,3];

let flag = ArrayUtil.isArray(arr);

flag // true

====== 2. flatten ======

将多维数组转化成一维数组。

let arr = [[1, 2, 3], [4, 5, 6], 7, [8]];

resultArr = ArrayUtil.flatten(arr);

resultArr // [1, 2, 3, 4, 5, 6, 7, 8]

====== 3. dislodge ======

给定两个数组,输出数组1里边在数组2里边不存在的元素。

let arr1 = [1,2,3,5,67,8];
let arr2 = [1,3,5,7,9];

ArrayUtil.dislodge(arr1,arr2); // [2,67,8]

====== 4. merge ======

将两个数组去重合并。

let arr1 = [1,2,3,5,67,8,8];
let arr2 = [1,3,5,7,9,9];

let result = ArrayUtil.merge(arr1,arr2));

result // [1,2,3,5,67,8,7,9]

====== 5. containAnother ======

判断数组1是否包含数组2。

// 
var array1 = [1,3,5,7,9];
var array2 = [1,3,5];

ArrayUtil.containAnother(array1, array2); // true

注意,当两个数组为空的时候返回false.

深拷贝

====== deepClone ====== 对传入的参数进行深度克隆。

// 如果我们传入的值是null或者不是一个对象,则会返回传入的值。
let resultNull = ArrayUtil.deepClone(null);
let resultStr = ArrayUtil.deepClone("xiaolb");
let resultNum = ArrayUtil.deepClone(22);

resultNull // null
resultStr // "xiaolb"
resultNum // 22

// 如果传入的是除上述情况的其他情况,传入什么输出什么。
ArrayUtil.deepClone(function(){})  // function(){}
ArrayUtil.deepClone({0:"a",1:"b",2:"c"}) // {0:"a",1:"b",2:"c"}
ArrayUtil.deepClone([1,2]) // [1,2]

缓存工具

缓存工具类目前分为几个函数:

====== 1. setCookie =====

建立cookie,一般用来存储用户名、密码之类的数据

名字 | 含义 | 是否必须 :----: | :----: | :----: name | cookie的名字 | require value | cookie的值| require expires | cookie的过期时间(格林威治时间)| option path | 默认当前的路径(必须为绝对路径)| option domain | 默认为当前文档位置的路径的域名部分| option secure | cookie只会被https传输(boolern)| option

//setCookie(name, value, expires, path, domain, secure)
let cookie = CookieUtil.setCookie('admin','root',new Date(new Date().getTime()-8*60*60*1000+100000))
cookie // "xlb=people; expires=Fri Jul 28 2017 08:09:57 GMT+0800 (中国标准时间)"

====== 2. getCookie =====

获取cookie的值

let value = CookieUtil.getCookie('admin')
value // 'root'

====== 3. getCookieVal =====

获取cookie的键值对

let value = CookieUtil.getCookieVal()

value // 'admin=root'

====== 4. deleteCookie =====

删除cookie

let value = CookieUtil.deleteCookie('xlb')
value // ''

字符串工具

字符串工具类目前分为几个函数:

====== 1. repeat ====== 使用矩阵快速幂来处理字符串连接。

第一个参数是字符串
第二个参数是数字
 // eg:
 StringUtil.repeat('sjdh',4) // 'sjdhsjdhsjdhsjdh'

传入的第一个参数必须为字符串,否则会报错

====== 2. padZeroLeft ======

在字符串左边填充"0"。

// eg1:
let  resultStr = StringUtil.padZeroLeft("xiaolb",9);
resultStr // "000xiaolb"

// eg2:
let  resultStr = StringUtil.padZeroLeft(12345678,9);
resultStr // "012345678"

如果传入的字符串的长度比传入的数组大的话,返回的是原字符串。

====== 3. trim ======

去掉字符串首尾的空格

let a = '              sjdh    '
var offset = StringUtil.trim(a);

offset // 'sjhd'

====== 4. OnlyInt ======

只能输入数字并且限定了长度

StringUtil.OnlyInt("sdf123456789",3); // 123

对象操作工具

对象操作工具类目前分为几个函数:

====== 1. isEmptyObject ======

判断对象是不是为空值,是的话返回true,否则为false.

// eg1:
var obj = {};
var resultObj = ObjectUtil.isEmptyObject(obj);

resultObj; // true


// eg2:
var obj = {"1":'1'};
var resultObj = ObjectUtil.isEmptyObject(obj);

resultObj; // false

====== 2. cloneObjExceptParam ======

克隆一个新的对象除了指定的属性名。

var obj = {"name":"xiaolb","sex":"man","age":"secret"};
var paramName = "name";
var resultObj = ObjectUtil.cloneObjExceptParam(obj,paramName);

resultObj; // {"sex":"man","age":"secret"}

历史浏览工具

历史浏览工具类目前分为几个函数:

====== 1. goBack ======

返回上一个页面,数据会全部刷新,不会保留。

goBack()

数学操作工具

数学操作工具类目前分为几个函数:

====== 1. randomInteger ======

在[start,end]内生成随机数整数,并返回该数。

var number = MathUtil.randomInteger(10,12);

number; //在[10,12]随机的一个整数。

数学操作工具

数学操作工具类目前分为几个函数:

====== 1. regPhone ======

校验是否为手机号

var value1 = RegularUtil.regPhone('15990357136')
var value1 = RegularUtil.regPhone('12990357136')
value1; // true
value2; // false

====== 2. regIdCard ======

校验是否为身份证号

var value1 = RegularUtil.regIdCard('445644123456789')
var value1 = RegularUtil.regIdCard('132456789465789123')
value1; // true
value2; // true

====== 3. regNumber ======

校验是否为正数

var value1 = RegularUtil.regNumber(456789)
var value1 = RegularUtil.regNumber(-132456789465789123)
value1; // true
value2; // false

====== 4. regNumWord ======

校验是否为字母+数字

var value1 = RegularUtil.regNumWord('f45s67s89s')
var value1 = RegularUtil.regNumWord('132456789465789123z@')
value1; // true
value2; // false

====== 5. pattern ======

自己写正则和检验值 pattern(reg, value)

var value1 = RegularUtil.pattern(/\d/,1)
value1; // true
