我尝试使用HTML Webpack插件创建静态HTML部分的设置,但遇到了一些错误。这是我当前的配置:

webpack.config.js

const webpack = require('webpack');
const path = require('path');
const ExtractTextWebpackPlugin = require('extract-text-webpack-plugin');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
const OptimizeCSSAssets = require('optimize-css-assets-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');

    let config = {
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, './public'),
    filename: 'app.js'
  },
  module: {
    loaders: [{
        test: /\.html$/,
        loader: 'html-loader'
    }],
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'babel-loader'
      },
      {
        test: /\.scss$/,
        use: ['css-hot-loader'].concat(ExtractTextWebpackPlugin.extract({
          fallback: 'style-loader',
          use: ['css-loader', 'sass-loader', 'postcss-loader'],
        })),
      },
      {
        test: /\.(jpe?g|png|gif|svg)$/i,
        loaders: ['file-loader?context=src/assets/images/&name=images/[path][name].[ext]', {
          loader: 'image-webpack-loader',
          query: {
            mozjpeg: {
              progressive: true,
            },
            gifsicle: {
              interlaced: false,
            },
            optipng: {
              optimizationLevel: 4,
            },
            pngquant: {
              quality: '75-90',
              speed: 3,
            },
          },
        }],
        exclude: /node_modules/,
        include: __dirname,
      },
    ]
  },
  plugins: [
    new HtmlWebpackPlugin({
        template: './src/template.html.ejs'
    }),
    new ExtractTextWebpackPlugin('main.css')
  ],
  devServer: {
    contentBase: path.resolve(__dirname, './public'),
    historyApiFallback: true,
    inline: true,
    open: true
  },
  devtool: 'eval-source-map'
}

module.exports = config;

if (process.env.NODE_ENV === 'production') {
  module.exports.plugins.push(
    new webpack.optimize.UglifyJsPlugin(),
    new OptimizeCSSAssets()
  );
}

template.html.ejs (位于./src下)

<%=require('./header.html')%>
  <body>
    testing schmesting
  </body>
  <%=require('./footer.html')%>
</html>

(footer.html和header.html位于./src下)

编辑:更新了代码,仍然发出:

&#34;错误中的错误:子编译失败:   模块解析失败:意外的令牌(1:0)   您可能需要一个适当的加载程序来处理此文件类型。
SyntaxError:意外的令牌(1:0)   模块解析失败:意外的令牌(1:2)   您可能需要一个合适的加载程序来处理此文件类型。&#34;

默认情况下,&#34; html-webpack-plugin&#34;将模板解析为&#34; underscore&#34; (也称为lodash)模板,你的&#34; template.html&#34;没错,错误是由webpack无法解决的问题导致的.html-loader&#39;为您的&#34; template.html&#34; <%= require('html-loader!./footer.html') %>,所以你需要安装&#34; html-loader&#34;对于webpack,并配置它:

在命令行中:

npm install html-loader

并为webpack配置,编辑webpack.config.js

...
module: {
    rules: [
     // ... 
        {
            test: /\.html$/, // tells webpack to use this loader for all ".html" files
            loader: 'html-loader'
        }
    ]
}

现在你可以运行&#34; webpack&#34;您将看到没有错误,但是生成的&#34; index.html&#34;不是你期望的,因为你的模板文件有&#34; .html&#34;扩展,webpack现在使用&#34; html-loader&#34;加载&#34; template.html&#34;而不是默认&#34; lodash loader&#34;,要解决此问题,您可以重命名&#34; template.html&#34; to&#34; template.html.ejs&#34; (或任何其他扩展名)制作&#34; html-webpack-plugin&#34;倒退。除了&#34; template.html&#34;,删除&#34; html-loader!&#34;还有一点点变化。从它:

<%= require('./footer.html') %>

现在它应该可以工作。

编辑发布我的代码以供参考:

/src/template.html.ejs

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>test</title>
        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">
    </head>
    <body>
        <h1>template</h1>
        <%=require('./footer.html')%>
    </body>
</html>

/src/footer.html

<footer>this is a footer</footer>

/webpack.config.js

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');

let config = {
    entry: {
        index: './src/js/index'
    },
    output: {
        path: path.resolve(__dirname, 'dist'),
        filename: '[name].js'
    },
    module: {
        rules: [
            {
                test: /\.html$/,
                loader: 'html-loader'
            }
        ],
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: './src/template.html.ejs'
        })
    ]
}


module.exports = config;

/package.json

{
  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "html-loader": "^0.5.1",
    "html-webpack-plugin": "^2.30.1",
    "webpack": "^3.10.0"
  }
}

/src/js/index.js

console.log("A test page!");

环境:

  • webpack 3.10.0
  • npm 5.6.0

&#34; /dist/index.html"的内容;运行webpack之后:

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>test</title>
        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">
    </head>
    <body>
        <h1>template</h1>
        <footer>this is a footer</footer>
    <script type="text/javascript" src="index.js"></script></body>
</html>

正如您可以看到&#34; footer.html&#34;的内容正确插入。

OLD ANSWER

方法1: Using "es6" template

  1. 安装&#34; html-loader&#34; npm install html-loader
  2. 添加&#34; html-loader&#34;到你的&#34; webpack.config.js&#34;使用&#34; .html&#34;加载文件扩展名,如:
  3. module: {
            rules: [{
                test: /\.html$/,
                loader: 'html-loader'
            }],
        }
    
    1. 添加interpolate标志以启用ES6模板字符串的插值语法,如下所示:
    2. plugins: [
              new HtmlWebpackPlugin({
                  template: '!!html-loader?interpolate!src/template.html'
              })
          ]
      
      1. 修改您的template.html以匹配ES6模板:
      2. <!DOCTYPE html>
        <html>
          <head>
            <meta charset="utf-8">
            <title></title>
          </head>
          <body>
            template
          </body>
          ${require('./footer.html')}
        </html>
        
        1. 运行webpack,它将
        2. 运行

          方法2:使用&#34;下划线&#34;模板

          关注&#34;方法1&#34;步骤1和2,然后:

          • 重命名&#34; template.html&#34;到&#34; template.html.ejs&#34;
          • 在&#34; webpack.config.js&#34;
          • 中将template: './src/template.html'更改为template: './src/template.html.ejs'
          • 运行webpack
