几个常用js库，别再重复造轮子了
color
==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 colorvar 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
==功能==：UUID.js-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");
// Get string representations of a UUID object
console.log(uuid.toString()); // "a0e0f130-8c21-11df-92d9-95795a3bcd40"
console.log(uuid.hexString); // "a0e0f130-8c21-11df-92d9-95795a3bcd40"
console.log(uuid.hexNoDelim); // "a0e0f1308c2111df92d995795a3bcd40"
console.log(uuid.bitString); // "101000001110000 ... 1100110101000000"
console.log(uuid.urn); // "urn:uuid:a0e0f130-8c21-11df-92d9-95795a3bcd40"
// Compare UUID objects
console.log(objV4.equals(objV1)); // false
// Get UUID version numbers
console.log(objV4.version); // 4
console.log(objV1.version); // 1
// Get internal field values in 3 different forms via 2 different accessors
console.log(uuid.intFields.timeLow); // 2699096368
console.log(uuid.bitFields.timeMid); // "1000110000100001"
console.log(uuid.hexFields.timeHiAndVersion); // "11df"
console.log(uuid.intFields.clockSeqHiAndReserved); // 146
console.log(uuid.bitFields.clockSeqLow); // "11011001"
console.log(uuid.hexFields.node); // "95795a3bcd40"
console.log(uuid.intFields[0]); // 2699096368
console.log(uuid.bitFields[1]); // "1000110000100001"
console.log(uuid.hexFields[2]); // "11df"
console.log(uuid.intFields[3]); // 146
console.log(uuid.bitFields[4]); // "11011001"
console.log(uuid.hexFields[5]);
rc-upload
==功能==： 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 、clipboard
==功能==：react 复制粘贴
npm install --save react react-copy-to-clipboard
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.</
