webpack-dev-server插件

webpack-dev-server是webpack官方提供的一个小型Express服务器。使用它可以为webpack打包生成的资源文件提供web服务。

webpack-dev-server 主要提供两个功能:

  • 为静态文件提供服务
  • 自动刷新和热替换(HMR)

HotModuleReplacementPlugin插件

HotModuleReplacementPlugin主要用于代码热替换(具体用途还不清楚,因为没有研究通透吧)

  • --quiet: don’t output anything to the console.
  • --no-info: suppress boring information.
  • --colors: add some colors to the output.

  • --hot --inline also adds the webpack/hot/dev-server entry.
  • --public: overrides the host and port used in --inline mode for the client (useful for a VM or Docker).
  • --lazy: no watching, compiles on request (cannot be combined with --hot).
