Question

所以我正在研究一个简单的纸牌游戏，在那里我有40张与纸牌有关的图像。我正在使用已经带有简单Webpack配置的Vue Cli。

因此，基本上，我将所有图像保存在静态文件夹中，如下所示：

当我构建用于生产的项目时，生成 dist 文件夹，它将创建如下图像：

这是我的webpack生产文件：

'use strict'
const path = require('path')
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config')
const merge = require('webpack-merge')
const baseWebpackConfig = require('./webpack.base.conf')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin')
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')

const env = process.env.NODE_ENV === 'testing'
  ? require('../config/test.env')
  : require('../config/prod.env')

const webpackConfig = merge(baseWebpackConfig, {
  module: {
    rules: utils.styleLoaders({
      sourceMap: config.build.productionSourceMap,
      extract: true,
      usePostCSS: true
    })
  },
  devtool: config.build.productionSourceMap ? config.build.devtool : false,
  output: {
    path: config.build.assetsRoot,
    filename: utils.assetsPath('js/[name].[chunkhash].js'),

    }),
    // extract css into its own file
    new ExtractTextPlugin({
      filename: utils.assetsPath('css/[name].[contenthash].css'),
      // Setting the following option to `false` will not extract CSS from codesplit chunks.
      // Their CSS will instead be inserted dynamically with style-loader when the codesplit chunk has been loaded by webpack.
      // It's currently set to `true` because we are seeing that sourcemaps are included in the codesplit bundle as well when it's `false`,

        : { safe: true }
    }),
    // generate dist index.html with correct asset hash for caching.
    // you can customize output by editing /index.html

module.exports = webpackConfig

感谢您的任何帮助

Answer 1

我假设您使用的是here，它不包括现成的图像优化。您可以轻松地（使用imagemin-webpack-plugin将其添加到Webpack配置中：

通过以下方式安装vuejs-templates/webpack：npm i -D imagemin-webpack-plugin

在build/webpack.prod.conf.js中，导入插件，然后在plugins[]中（在CopyWebpackPlugin之后）进行配置：

const ImageminPlugin = require('imagemin-webpack-plugin').default;

const webpackConfig = merge(baseWebpackConfig, {
  plugins: [
    // ...
    new ImageminPlugin({
      test: /\.(jpe?g|png|gif|svg)$/i,
      /* other ImageMin configs */
    })
  ]
}

在ImageminWebpackPlugin之后运行CopyWebpackPlugin，确保通过ImageMin优化运行从static复制的图像。

ImageminWebpackPlugin

Answer 2

在当前版本的Vue中，您可以使用如下所示的vue.config.js：

const ImageminPlugin = require('imagemin-webpack-plugin').default;

module.exports = {
  configureWebpack: {
    plugins: [
      new ImageminPlugin({
        disable: process.env.NODE_ENV !== 'production',
      })
    ]
  }
}

这将在生产版本上启用Imagemin，但在开发版本上跳过。

Answer 3

您可以尝试一下。它可以帮助您自动缩小图像，而无需复杂的算法配置。它还可以帮助您编码（和内联）图像（比url-loader更灵活）。

https://github.com/GaoYYYang/image-optimize-loader

module.exports = {
  module: {
    rules: [
      {
        test: /\.(png|jpe?g|webp|git|svg|)$/i,
        use: [
          {
            loader: 'img-optimize-loader'
          },
        ],
      },
    ],
  },
};

Vue Webpack配置不会缩小图像
