color

www.npmjs.com/package/col…

功能：JavaScript库，用于不可变的颜色转换和对CSS颜色字符串的支持。

npm install color

var color = Color('###7743CE').alpha(0.5).lighten(0.5);
console.log(color.hsl().string());  // 'hsla(262, 59%, 81%, 0.5)'
 
console.log(color.cmyk().round().array());  // [ 16, 25, 0, 8, 0.5 ]
 
console.log(color.ansi256().object());  // { ansi256: 183, alpha: 0.5 }

uuidjs

JavaScript的RFC兼容UUID生成器

// Create a version 4 (random number-based) UUID object
var objV4 = UUID.genV4();
 
// Create a version 1 (time-based) UUID object
var objV1 = UUID.genV1();
 
// Create a UUID object from a hexadecimal string
var uuid = UUID.parse("a0e0f130-8c21-11df-92d9-95795a3bcd40");

rc-upload

文件上传下载拖拽文件 及文件夹等

var Upload = require('rc-upload');
var React = require('react');
React.render(<Upload />, container);

react-copy-to-clipboard

react 复制粘贴

• 1.安装

npm install --save react react-copy-to-clipboard

• 2.引用

import React from 'react';
import ReactDOM from 'react-dom';
import {CopyToClipboard} from 'react-copy-to-clipboard';
 
class App extends React.Component {
  state = {
    value: '',
    copied: false,
  };
 
  render() {
    return (
      <div>
        <input value={this.state.value}
          onChange={({target: {value}}) => this.setState({value, copied: false})} />
 
        <CopyToClipboard text={this.state.value}
          onCopy={() => this.setState({copied: true})}>
          <span>Copy to clipboard with span</span>
        </CopyToClipboard>
 
        <CopyToClipboard text={this.state.value}
          onCopy={() => this.setState({copied: true})}>
          <button>Copy to clipboard with button</button>
        </CopyToClipboard>
 
        {this.state.copied ? <span style={{color: 'red'}}>Copied.</span> : null}
      </div>
    );
  }
}
 
const appRoot = document.createElement('div');
document.body.appendChild(appRoot);
ReactDOM.render(<App />, appRoot);

numeral

一个用于格式化和处理数字的javascript库。

var value = myNumeral.value();
// 1000

var myNumeral2 = numeral('1,000');

var value2 = myNumeral2.value();
// 1000

Moment.js

一个JavaScript日期库，用于解析，验证，操作和格式化日期

moment().format('MMMM Do YYYY, h:mm:ss a'); // December 22nd 2020, 10:55:15 am
moment().format('dddd');                    // Tuesday
moment().format("MMM Do YY");               // Dec 22nd 20
moment().format('YYYY [escaped] YYYY');     // 2020 escaped 2020
moment().format();    

Day.js

Day.js 是一个轻量的处理时间和日期的 JavaScript 库，和 Moment.js 的 API 设计保持完全一样. 如果您曾经用过 Moment.js, 那么您已经知道如何使用 Day.js

dayjs().format('{YYYY} MM-DDTHH:mm:ss SSS [Z] A') // 展示

dayjs()
  .set('month', 3)
  .month() // 获取

dayjs().add(1, 'year') // 处理

dayjs().isBefore(dayjs()) // 查询

milliseconds

用于将时间转换为毫秒。

var ms = require('milliseconds');
ms.seconds(2); // 2000
ms.minutes(2); // 120000
ms.hours(2);   // 7200000
ms.days(2);    // 172800000
ms.weeks(2);   // 1209600000
ms.months(2);  // 5259600000
ms.years(2);   // 63115200000

filesize

filesize.js提供了一种简单的方法来从数字（浮点数或整数）或字符串中获取人类可读的文件大小字符串。

npm i filesize


filesize(500);                        // "500 B"
filesize(500, {bits: true});          // "4 Kb"
filesize(265318, {base: 10});         // "265.32 kB"
filesize(265318);                     // "259.1 KB"
filesize(265318, {round: 0});         // "259 KB"
filesize(265318, {output: "array"});  // [259.1, "KB"]
filesize(265318, {output: "object"}); // {value: 259.1, symbol: "KB", exponent: 1}
filesize(1, {symbols: {B: "Б"}});     // "1 Б"
filesize(1024);                       // "1 KB"
filesize(1024, {exponent: 0});        // "1024 B"
filesize(1024, {output: "exponent"}); // 1
filesize(265318, {standard: "iec"});  // "259.1 KiB"
filesize(265318, {standard: "iec", fullform: true}); // "259.1 kibibytes"
filesize(12, {fullform: true, fullforms: ["байтов"]});  // "12 байтов"
filesize(265318, {separator: ","});   // "259,1 KB"
filesize(265318, {locale: "de"});   // "259,1 KB"

Lodash

函数工具类库

// Load the full build.
var _ = require('lodash');
// Load the core build.
var _ = require('lodash/core');
// Load the FP build for immutable auto-curried iteratee-first data-last methods.
var fp = require('lodash/fp');
 
// Load method categories.
var array = require('lodash/array');
var object = require('lodash/fp/object');
 
// Cherry-pick methods for smaller browserify/rollup/webpack bundles.
var at = require('lodash/at');
var curryN = require('lodash/fp/curryN');

        newLists[newLists.length - 1].children.push(item)
      } else {

Echarts图表

1.安装

1.   npm install echarts --save
//package.json中有此项，代表安装成功

2. 引入全部组件

如果你项目里需要用到各种各样的图表，建议使用本条。

• main.js 中引入

 // 引入echarts
import echarts from 'echarts'
Vue.prototype.$echarts = echarts

• 使用

export default {
  name: 'hello',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  },
  mounted(){
    this.drawLine();
  },
  methods: {
    drawLine(){
        // 基于准备好的dom，初始化echarts实例
        let myChart = this.$echarts.init(document.getElementById('myChart'))
        // 绘制图表
        myChart.setOption({
            title: { text: '在Vue中使用echarts' },
            tooltip: {},
            xAxis: {
                data: ["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"]
            },
            yAxis: {},
            series: [{
                name: '销量',
                type: 'demo',
                data: [5, 20, 36, 10, 10, 20]
            }]
        });
    }
  }
}

• 效果图

 3. 按需引入（项目中少量图表的情况下，采用此条）

// 引入基本模板
let echarts = require("echarts/lib/echarts");
// 引入柱状图组件
require("echarts/lib/chart/bar");
// 引入提示框和title组件
require("echarts/lib/component/tooltip");
require("echarts/lib/component/title");
// 不引入这个会报错 xAxis "0" not found
require("echarts/lib/component/grid");

4. 封装成组件echarts.vue

<template>
  <div>
    <div :style="{ height: height, width: width }" :id="id"></div>
  </div>
</template>
<script>
// 引入基本模板
let echarts = require("echarts/lib/echarts");
// 引入柱状图组件
require("echarts/lib/chart/bar");
// 引入提示框和title组件
require("echarts/lib/component/tooltip");
require("echarts/lib/component/title");
// 不引入这个会报错 xAxis "0" not found
require("echarts/lib/component/grid");
// import 'echarts/lib/component/grid';
export default {
  name: "echarts",
  props: {
    height: {
      type: String,
      default: "500px",
    },
    width: {
      type: String,
      default: "500px",
    },
    id: {
      type: String,
      default: "demo",
    },
  },
  data() {
    return {};
  },
  mounted() {
    this.drawLine();
  },
  methods: {
    drawLine() {
      // 基于准备好的dom，初始化echarts实例
      console.log(this.id);
      let myChart = echarts.init(document.getElementById(this.id));
      // 绘制图表
      myChart.setOption({
        title: { text: "在Vue中使用echarts" },
        tooltip: {},
        xAxis: {
          type: 'category',
          data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"]
        },
        yAxis: {},
        series: [
          {
            name: "销量",
            type: "bar",
            data: [5, 20, 36, 10, 10, 20],
          },
        ],
      });
    },
  },
};
</script>

5. 使用此组件

<template>
   <div class="main-con">
     <echarts
     :width="width"
     :height="height"
     :id="id"></echarts>
   </div>
</template>
<script>
import echarts from './echarts.vue'
export default {
  name: 'chartShow',
  data(){
    return{
      width: '100%',
      height: '500px',
      id: 'chartShow'
    }
  },
  components:{
    echarts
  }
}
</script>
<style lang="scss" scoped>
.main-con{
  width: 100%;
  height: 100%;
  padding: 20px;
}
</style>
