文件指纹是什么? 怎么用?

文件指纹是打包后输出的文件名的后缀。

  • Hash：和整个项目的构建相关，只要项目文件有修改，整个项目构建的 hash 值就会更改
  • Chunkhash：和 Webpack 打包的 chunk 有关，不同的 entry 会生出不同的 chunkhash
  • Contenthash：根据文件内容来定义 hash，文件内容不变，则 contenthash 不变
  • JS文件指纹设置: output 的 filename 中设置,使用 chunkhash
  • CSS的文件指纹设置: MiniCssExtractPlugin插件中的filename设置,使用contenthash
  • 图片的文件指纹设置: file-loader 中的 options中设置 使用 hash
