前端技术之:webpack热模块替换(HMR)

第一步:安装HMR中间件:
npm install --save-dev webpack-hot-middleware
第二步:webpack配置中引入webpack对象

const webpack = require('webpack’);

第三步:增加devServer配置项:

hot: true

第四步:增加热模块替换插件:

new webpack.HotModuleReplacementPlugin()

注意:
1、ExtractTextPlugin插件可能会导致HMR无效。
另外,还可以通过使用web-dev-server —hotOnly参数来启用HMR。

React、Vue、Angular相关技术,请参考以下内容:

  • React Hot Loader: Tweak react components in real time.
  • Vue Loader: This loader supports HMR for vue components out of the box.
  • Elm Hot Loader: Supports HMR for the Elm programming language.
  • Angular HMR: No loader necessary! A simple change to your main NgModule file is all that's required to have full control over the HMR APIs.
