[英]webpack not generating bundle.js
我正在使Web应用程序使用react和php,并且我正在将webpack用于es6到js,所以我生成了文件,但是我对webpack输出bundle.js文件有问题。
这是我的webpack.config.js
const webpack = require('webpack');
module.exports = {
entry: [
'./src/index.jsx'
],
output: {
path: '/dist',
publicPath: '/dist/',
filename: 'bundle.js'
},
devServer: {
contentBase: './dist',
},
module: {
rules: [{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
presets: ['env', 'react']
}
}
}, {
test: /(\.css|.scss)$/,
use: [{
loader: "style-loader"
}, {
loader: "css-loader"
}, {
loader: "sass-loader"
}]
}]
},
resolve: {
extensions: ['*', '.js', '.jsx']
}
};
这是我的package.json
{
"name": "react-app",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "webpack-dev-server --history-api-fallback --progress --colors --config ./webpack.config.js"

}
}
为什么webpack生成并将bundle.js给我,放到dist文件夹中? 仅将其保存到内存中并显示在本地主机上。 我想将此反应应用程序与php一起使用,但我无法处理bundle.js。 问题出在哪里,为什么Webpack没有生成js文件。 请帮我
您的webpack配置输出出现问题。
首先在webpack.config.js中导入const path = require('path')
并更改output
文件,如下所示:
output: {
path: path.resolve(__dirname, 'dist'),
publicPath: '/dist/',
filename: 'bundle.js'
}
并在script
文件"build": "webpack -p --progress"
中将以下脚本添加到您的package.json中"build": "webpack -p --progress"
运行npm run build
这是webpack开发服务器的预期行为。 如果要在磁盘上生成输出,则需要运行webpack
,例如:
"scripts": {
"start": "webpack-dev-server --history-api-fallback ...",
"build": "webpack"
}
然后运行npm build
。 对于生产,还应该设置NODE_ENV=production
,例如,使用cross-env :
"build": "cross-env NODE_ENV=production webpack"
