Question

我开发了一个VueJS项目。我运行命令后

npm run build

生成包含build.js文件和图像的dist文件夹。

但/ dist中没有index.html文件。

我的项目结构如下所示

我的webpack.config.js看起来像这样

let path = require('path');

let webpack = require('webpack');

let UglifyJsPlugin = require('uglifyjs-webpack-plugin');

let axios = require('axios');

let url = axios.defaults.baseURL;

module.exports = {
    entry: './src/main.js',
    output: {
        path: path.resolve(__dirname, './dist'),
        publicPath: '/dist/',
        filename: 'build.js'
    },
    plugins: [
        new HtmlWebpackPlugin(), // Generates default index.html
        new HtmlWebpackPlugin({ // Also generate a test.html
            filename: 'openseadragon.html',
            template: './openseadragon.html'
        })
    ],
    module: {
        rules: [{
                test: /\.vue$/,
                loader: 'vue-loader',
                options: {
                    loaders: {}
                    // other vue-loader options go here
                }
            },
            {
                test: /\.js$/,
                loader: 'babel-loader',
                exclude: /node_modules/
            },
            {
                test: /\.(png|jpg|gif|svg)$/,
                loader: 'file-loader',
                options: {
                    name: '[name].[ext]?[hash]'
                }
            }
        ]
    },
    resolve: {
        alias: {
            'vue$': 'vue/dist/vue.esm.js',
        },
        extensions: ['*', '.js', '.vue', '.json']
    },

    devServer: {
        proxy: {
            '/api': {
                target: `${url}`
            }
        },
        historyApiFallback: true,
        noInfo: true
    },
    performance: {
        hints: false
    },
    devtool: '#eval-source-map'
}

if (process.env.NODE_ENV === 'production') {
    module.exports.devtool = '#source-map'
        // http://vue-loader.vuejs.org/en/workflow/production.html
    module.exports.plugins = (module.exports.plugins || []).concat([
        new webpack.DefinePlugin({
            'process.env': {
                NODE_ENV: '"production"'
            }
        }),
        new UglifyJsPlugin({
            "uglifyOptions": {
                compress: {
                    warnings: false
                },
                sourceMap: true
            }
        }),
        new webpack.LoaderOptionsPlugin({
            minimize: true
        })
    ])
}

如您所见，index.html文件位于src目录之外。有没有什么办法可以生成index.html文件而不必将其放入/ src目录？

在构建之后，我尝试在Heroku上运行应用程序以确保它已加载。我收到这样的错误。

build.js有什么问题？

以下是原始index.html

这是生成的index.html， /dist/index.html

Answer 1

您可以使用CopyWebpackPlugin

module.exports = {
  plugins: [
    new CopyWebpackPlugin([
      { from: './index/html', to: 'relative/path/to/dest/' }
    ])
  ]
}

HtmlWebpackPlugin是另一种选择，它可以自动为你注入js脚本

VueJS - “npm run build”不会在dist文件夹中生成index.html文件
