HotModuleReplacementPlugin主要用於代碼熱替換(具體用途還不清楚,由於沒有研究通透吧)web

 

1、webpack-dev-server插件說明npm

  • --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).
