分享Webpack-dev-server无法将打包后文件正确引入html中导致无法得到正确结果
webpack.config.js 的代码
module.exports = {
entry: __dirname + "/app/main.js", //已多次提及的唯一入口文件
output: {
path: __dirname + "/public", //打包后的文件存放的地方
filename: "bundle.js" //打包后输出文件的文件名
},
devtool: 'eval-source-map',
devServer: {
contentBase: __dirname + "/public", //本地服务器所加载的页面所在的目录
historyApiFallback: true, //不跳转
inline: true //实时刷新
},
module: {
rules: [
{
test: /(\.jsx|\.js)$/,
use: {
loader: "babel-loader",
options: {
presets: [
"es2015", "react"
]
}
},
exclude: /node_modules/
}
]
}
};
package.json的代码
{
"name": "simple_sample",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error:no test specified\" && exit1",
"start": "webpack-dev-server --inline"
},
"author": "",
"license": "ISC",
"devDependencies": {
"babel-core": "^6.26.0",
"babel-loader": "^7.1.2",
"babel-preset-es2015": "^6.24.1",
"babel-preset-react": "^6.24.1",
"react": "^16.0.0",
"react-dom": "^16.0.0",
"webpack": "^3.6.0",
"webpack-dev-server": "^2.9.1"
}
}
main.js的代码
import React from 'react';
import {render} from 'react-dom';
import Greeter from './Greeter';
render(<Greeter />, document.getElementById('root'));
Greeter.js的代码
import React, {Component} from 'react';
import config from './config.json';
class Greeter extends Component {
render() {
return (
<div>
{config.greetText}
</div>
);
}
}
export default Greeter
config.json的代码
{
"greetText": "Hi There and greeting from Json!!"
}
index.html的代码
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Webpack Sample Project</title>
</head>
<body>
<h2>Temp Webpack</h2>
<div id="root"></div>
<script type="text/javascript" src="bundle.js"></script>
</body>
</html>
结果截图
可以看出并没有显示config.json文件的字符串，但如果直接将srcipts的start改为webpack,然后执行npm start得到bundle.js文件后运行index.html，是可以得到正确结果，所以可能是webpack-dev-server的配置出问题,请大牛们救救！
