使用文件加载器加载 Webpack handlebars 图像

Question

不确定我是否正确地处理了这个问题，但我正在尝试在 Webpack 中使用 handlebars 模板和文件加载器。我遇到的问题是我拥有的带有图像的资产文件夹没有被复制到 dist 文件夹，并且 img src 正在使用文件加载器解析以拉入图像。如果我找不到有帮助的 post，请分享，或者如果有一篇文章包含有用的信息，我也会采纳。

在此先感谢您的帮助。

Webpack.config

const webpack = require('webpack');

module.exports = {
  entry: "./src/index.js",
  plugins: [
    new webpack.LoaderOptionsPlugin({
      options: {
        handlebarsLoader: {}
      }
    })
  ],
  module: {
    rules: [
      {
        test: /\.handlebars$/,
        loader: "handlebars-loader"
      },
      {
        test: /\.html$/,
        use: ["html-loader"]
      },
      {
        test: /\.(svg|png|jpe?g|gif)$/i,
        use: {
          loader: "file-loader",
          options: {
            name: "[name].[hash].[ext]",
            outputPath: "imgs/",
            useRelativePath: true
          }
        }
      }
    ]
  }
}

把手模板

  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <title>{{ htmlWebpackPlugins.options.title }}</title>
</head>

<body>
  {{> templates/title}}
  <img src="./assets/serve.svg" alt="Serve svg" />
</body>

</html>

您需要安装 CopyWebpackPlugin 才能将资源复制到 dist 文件夹。我在 webpack 4 中遇到了同样的问题。

尝试使用这个插件

const CopyWebpackPlugin = require('copy-webpack-plugin');

plugins: [

      new CopyWebpackPlugin([
                {
                    from: './src/assets',
                    to: './assets'
                }
            ])
]
