使用HTML Webpack插件的部分错误

问题描述 投票:12回答:1

我正在尝试使用HTML Webpack插件创建具有静态HTML部分的设置,但遇到了一些错误。这是我目前的配置:

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,仍然会出现问题: “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器来处理此文件类型。 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器来处理这种文件类型。“

(编辑:2017-12-20将“装载机”移至“规则”)

默认情况下,“html-webpack-plugin”将模板解析为“underscore”(也称为lodash)模板,你的“template.html”没有错,错误是由webpack无法为你解决'html-loader'引起的“template.html”<%= require('html-loader!./footer.html') %>,所以你需要为webpack安装“html-loader”,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'
        }
    ]
}

到现在你可以运行“webpack”你会看到没有错误,但生成的“index.html”不是你想象的,因为你的模板文件有“.html”扩展名,webpack现在使用“html-loader”加载“ template.html“而不是默认”lodash loader“,为了解决这个问题,您可以将”template.html“重命名为”template.html.ejs“(或任何其他扩展名),以使”html-webpack-plugin“回退。除了“template.html”之外还有一点点变化,删除“html-loader!”从中:

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

现在它应该工作。


编辑发布我的代码以供参考:

/双人床/template.HTML.额就是

<!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>

/双人床/footer.HTML

<footer>this is a footer</footer>

/Web pack.config.就是

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"
  }
}

/双人床/就是/index.就是

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

环境:

  • webpack 3.10.0
  • 高于5.6.0

运行webpack后“/dist/index.html”的内容:

<!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>

正如您所见,“footer.html”的内容已正确插入。


老答复

方法1:Using "es6" template

  1. 安装npm install html-loader的“html-loader”
  2. 将“html-loader”添加到“webpack.config.js”以加载扩展名为“.html”的文件,如:
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:
plugins: [
        new HtmlWebpackPlugin({
            template: '!!html-loader?interpolate!src/template.html'
        })
    ]
  1. 修改您的template.html以匹配ES6模板:
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title></title>
  </head>
  <body>
    template
  </body>
  ${require('./footer.html')}
</html>
  1. 运行webpack,它会工作

方法2:使用“下划线”模板

按照“方法1”步骤1和2,然后:

  • 将“template.html”重命名为“template.html.ejs”
  • 在“webpack.config.js”中将template: './src/template.html'更改为template: './src/template.html.ejs'
  • 运行webpack
