啟用dll

• 啟用dll後，我們的動態庫文件每次打包生成的vendor的[chunkhash]值就會一樣，其值可以是true/false,也可以製定特定的代码库

  
  module.exports = {
  dll: true
  }

module.exports = { dll: [ 'dep-a', 'dep-b/some/nested/file.js' ] }

靜態資源路徑

• 相對路徑

• 靜態資源路徑以 @ 開頭代表 <projectRoot>/src
• 靜態資源路徑以 ~ 開頭，可以引入 node modules 內的資源

webpack 配置修改

• 對模塊處理配置

  module.exports = {
  chainWebpack: config => {
  config.module
  .rule('js')
  .include
  .add(/some-module-to-transpile/)  // 要处理的模块
  }
  }

• 修改webpack Loader配置

  module.exports = {
  chainWebpack: config => {
  config.module
  .rule('scss')
  .use('sass-loader')
  .tap(options =>
  merge(options, {
  includePaths: [path.resolve(__dirname, 'node_modules')],
  })
  )
  }
  }

  修改webpack Plugin配置

  module.exports = {
  chainWebpack: config => {
  config
  .plugin('html')
  .tap(args => {
  return [/* new args to pass to html-webpack-plugin's constructor */]
  })
  }
  }
