先上效果

开发环境要求

需要事先安装node及npm

前期准备

1.创建文件夹react-echarts-editor
2.在项目根目录(以下称根目录)下创建src目录
3.在项目根目录下创建dist目录
4.在src目录下创建app.js文件(该文件就来一个react-echarts版的hello world)

import React from 'react';

import ReactDOM from 'react-dom';

import ReactEcharts from "echarts-for-react";

class EchartsEditor extends React.Component{

    constructor(props) {

        super(props);

        this.state = {

            echartsOption:  {

                xAxis: {

                    type: 'category',

                    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']

                },

                yAxis: {

                    type: 'value'

                },

                series: [{

                    data: [820, 932, 901, 934, 1290, 1330, 1320],

                    type: 'line'

                }]

            }

        };

    }

    render(){

        return(

            <div>

                <ReactEcharts option={this.state.echartsOption} />

            </div>

    );

    }

}

ReactDOM.render(<EchartsEditor/>,document.getElementById("container"));

5.在dist目录下创建index.html文件

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>Title</title>

</head>

<body>

<div id="container"></div>

</body>

<script src="bundle.js"></script>

</html>

6.在根目录下创建使用命令创建package.json

npm init -y

7.在根目录下创建使用命令安装webpack、babel、react、echarts 、lodash

npm install webpack webpack-cli --save-dev

npm install babel-preset-flow babel-preset-env babel-preset-stage- --save-dev

npm install react react-dom echarts echarts-for-react lodash --save

安装完后package.json如下:

{

  "name": "react-echarts-editor",

  "version": "0.0.1",

  "dependencies": {

    "echarts": "^4.2.0-rc.2",

    "echarts-for-react": "^2.0.15-beta.0",

    "lodash": "^4.17.11",

    "react": "^16.7.0",

    "react-dom": "^16.7.0"

  },

  "devDependencies": {

    "babel-preset-env": "^1.7.0",

    "babel-preset-flow": "^6.23.0",

    "babel-preset-stage-1": "^6.24.1",

    "webpack": "^4.28.4",

    "webpack-cli": "^3.2.1"

  }

}

8.在根目录下创建webpack.config.js

const path = require('path');

module.exports = {

    entry: './src/app.js',

    output: {

        filename: 'bundle.js',

        path: path.resolve(__dirname, 'dist')

    },

    'module': {

        'rules': [

            {

                'test': /\.(js|jsx)?$/,

                'exclude': /node_modules/,

                use: [{

                    loader: "babel-loader",

                    options: {presets:["env","flow","react","es2015","stage-1"]}

                }]

            }

        ]

    }

}

9.项目结构最后如下:

测试项目

在根目录下执行:

npx webpack

用浏览器打开dist目录下的index.html如下则成功:

以上简单的react+webpack架构就完成了。

编写一些工具函数

createOrSet函数接收echarts的option,propChain为属性链，value为要设置的值(不懂的可以先用)

createOrSet=(echartsOption,propChain,value)=>

    {

        if(_.isString(value)||_.isBoolean(value)||_.isNumber(value)||_.isArray(value)) {

            _.set(echartsOption, propChain, value);

        }else if(_.isObject(value)){

            if(_.get(echartsOption,propChain)===undefined){

                _.set(echartsOption, propChain, value);

            }else{

                let objBefore = _.get(echartsOption,propChain);

                let objAfter = {...objBefore,...value};

                _.set(echartsOption, propChain, objAfter);

            }

        }

        return echartsOption;

    }

    createOrSetProp=(propChain,value)=>

    {

        let echartsOption = _.cloneDeep(this.state.echartsOption);

        echartsOption=this.createOrSet(echartsOption,propChain,value);

        this.setState({echartsOption: echartsOption});

    }

编写属性配置界面

<div style={{width:'50%',float:'left'}}>

    <input type="text"  style={{'width': '100%',float:'left'}} placeholder="输入图表标题" value={_.get(this.state.echartsOption,'title.text','')} onChange={e=>this.createOrSetProp('title.text',e.target.value)} />

    <input type="range" style={{'width': '100%',float:'left'}} defaultValue='60'    min="1" max="100" onChange={(e)=>{this.createOrSetProp('grid.top',e.target.value)}}/>

    <input type="range" style={{'width': '100%',float:'left'}} defaultValue='60'    min="1" max="100" onChange={(e)=>{this.createOrSetProp('grid.bottom',e.target.value)}}/>

    <input type="range" style={{'width': '100%',float:'left'}} defaultValue='10'   min="1" max="100" onChange={(e)=>{this.createOrSetProp('grid.left',e.target.value+'%')}}/>

    <input type="range" style={{'width': '100%',float:'left'}} defaultValue='10'  min="1" max="100" onChange={(e)=>{this.createOrSetProp('grid.right',e.target.value+'%')}}/>

</div>
