开发缘由：因为一个很重要的朋友需要绘制一些 Charts，但是嫌弃手绘太慢，因此这次放假写了这个小东西
当前进度：简单的 Demo Charts 展示，包括 AreaChart, BarChart, ComposedChart, LineChart, PieChart
测试文件：src/common/files/info.xlsx
附上
Recharts
React-Route
先上两张照片吧
1、版本
2、创建项目
因为公司使用的 react+antd+ts, 虽然 antd 前两天搞了个圣诞惊吓，但是毋庸置疑，这个组件库做的确实很好啊，我不怕被喷，辩证一分为二，不能因为别人犯一点的错误，就否认人家吧，废话不多说，还是讲本文的主题吧首先先安装 create-react-app
npm i -g create-react-app
create-react-app Charts –scripts-version=react-scripts-ts-antd
然后安装 react-route-dom 和 recharts
yarn add react-route-dom
or
npm i react-route-dom –save
npm i recharts –save
因为 TS 检查较为严格，所以，我对 TS 有一些我自己需要 rules 的配置 tslint.js
{
“extends”: [“tslint:recommended”, “tslint-react”, “tslint-config-prettier”],
“linterOptions”: {
“exclude”: [
“config/**/*.js”,

TS 初试
React-Route 4.x 提供给我们使用的都是以组件形式存在的。我们使用的时候就像我们以前使用组件那样使用就行了，详见 React-Route 官方文档。
菜单栏，我觉得日后可能还会增加其他的 Charts，所以我将菜单通过配置文件来控制，增加复用性。
SideMenu.tsx
import React, {Component} from ‘react’;
import {Link} from ‘react-router-dom’;
import classnames from ‘classnames’;
import moment from ‘moment’;
import ‘./index.scss’;
import {menus} from ‘./menus’;
import {Layout, Menu, Icon} from ‘antd’;
import Timer from ‘src/components/Timer/Timer’;
const {Header, Footer, Sider, Content} = Layout;
const {SubMenu} = Menu;
interface SideMenuProps {
children?: any;
}
export default class SideMenu extends Component<SideMenuProps, any> {
public state = {
collapsed: false,
selectedKeys: [menus[0].key],
};
public toggle = () => {
this.setState({
collapsed: !this.state.collapsed
});
};
render() {
const {collapsed, selectedKeys,} = this.state
return (
<Layout className=”side-menu”>
<Sider trigger={null} collapsible={true} collapsed={collapsed}>
<div className=”logo”>
<img src={require(‘src/common/images/logo.png’)} />
<a href=”https://github.com/Rain120/charts” target=”_blank”>
<span className={classnames(“title”)}><Icon type=”github” /></span>
</a>
<a href=”https://www.zhihu.com/people/yan-yang-nian-hua-120/activities” target=”_blank”>
<span className={classnames(“title”)}><Icon type=”zhihu” /></span>
</a>
</div>
<Menu theme=”dark” mode=”inline” defaultSelectedKeys={selectedKeys}>
{
menus && menus.map(menu => (
menu.children
? (
<SubMenu key={menu.key} title={<span><Icon type={menu.icon} /><span>{menu.text}</span></span>}>
{
menu.children.map(item => (
<Menu.Item key={item.key}>
<Link to={item.path}>{item.text}</Link>
</Menu.Item>
))
}
</SubMenu>
) : (
<Menu.Item key={menu.key}>
<Link to={menu.path} style={{overflow: ‘hidden’}}><Icon type={menu.icon} />{menu.text}</Link>
</Menu.Item>
)
))
}
</Menu>
</Sider>
<Layout className=”r-content”>
<Header>
<Icon
className=”trigger”
type={collapsed ? ‘menu-unfold’ : ‘menu-fold’}
onClick={this.toggle}
/>
<Timer timerStyle=”timer” />
</Header>
<Content style={{margin: ‘1rem’, padding: ‘1rem’, background: ‘#fff’, minHeight: ’25rem’,}}>
{this.props.children}
</Content>
<Footer style={{textAlign: ‘center’}}>

</Layout>
);
}
}

获取 Excel 的数据是通过使用大佬的 xlsx 插件来实现的，详见 XLSX 官网。
npm i xlsx -S
因为这次项目没有后端，所以其实我们对 Excel 文件的解析是在 upload 之前完成的
public beforeUpload = (file: any, fileList: any) => {
var rABS = true;
const f = fileList[0];
var reader = new FileReader();
reader.onload = (e: any) => {
let data: any = e.target.result;
if (!rABS) {
data = new Uint8Array(data);
}
var workbook = XLSX.read(data, {
type: rABS ? ‘binary’ : ‘array’
});
// more sheet
workbook.SheetNames.map(item => {
var worksheet = workbook.Sheets[item];
var jsonArr = XLSX.utils.sheet_to_json(worksheet, { header: 1});
this.handleImpotedJson(jsonArr);
})
};
if (rABS) {
reader.readAsBinaryString(f);
} else {
reader.readAsArrayBuffer(f);
}
return false;
}
upload config
const props = {
accept: ‘application/vnd.openxmlformats-officedocument.spreadsheetml.sheet’,
name: ‘file’,
headers: {
authorization: ‘authorization-text’,
},
multiple: false,
action: ”,
beforeUpload: (file, fileList) => this.beforeUpload(file, fileList),
onChange(info) {
const status = info.file.status;
if (status !== ‘uploading’) {
console.log(info.file, info.fileList);
}
if (status === ‘done’) {
message.success(`${info.file.name} file uploaded successfully.`);
} else if (status === ‘error’) {
message.error(`${info.file.name} file upload failed.`);
}
},
};
Charts 组件因为使用的 Charts 比较多，所以使用 recharts 提供的组件 ResponsiveContainer 为了使得这些 Charts 不够缩放的影响。但是当前做的这些 Charts 大部分都是相同的结构，所以相同的部分应该抽离出来。
因为其他的 Charts 都差不多，这里我只说一下 LineCharts
import React, {Component} from ‘react’;
import WrapperCharts from ‘./WrapperCharts’;
import ‘./index.scss’;
import {
Line,
Legend,
Tooltip,
XAxis,
YAxis,
CartesianGrid,
LineChart,
Label,
} from “recharts”;
export const COLOR_LISTS = [‘#8884d8’, ‘#cf6868’, ‘#3fb549’, ‘#a6d41f’, ‘#8ad4d8’, ‘#cfdd68’, ‘#354449’, ‘#a75d1f’];
interface LineChartsProps {
data?: any;
names?: any;
}
export default class LineCharts extends Component<LineChartsProps, any> {
render() {
const {data, names} = this.props;
return (
<WrapperCharts class_name=”line-charts”>
<LineChart data={data}>
<CartesianGrid />
{
names && <XAxis dataKey={names[0].dataKey} name={names[0].name} />
}
<YAxis />
<Tooltip />
<Legend />
{
names && names.slice(1).map((item, index) => (
<Line type=”monotone” dataKey={item.dataKey} key={index} name={item.name} stroke={COLOR_LISTS[index]} />
))
}
<Label />
</LineChart>
</WrapperCharts>
)
}
}
github page deploy
npm i -g gh-pages
package.json 配置
“predeploy”: “yarn run build”,
“deploy”: “gh-pages -d build”
部署
yarn run deploy

以上就是这两天做的小东西，写的和讲的都很潦草，请看管轻喷。
