打字稿和HMR不起作用

Question

我有使用Typescript,ReactJS和Webpack构建的前端应用程序.
我正在尝试启用HMR.
这些是启动脚本

"build": "NODE_ENV=production $(npm bin)/webpack --watch",
"dev": "$(npm bin)/nodemon --exec \"$(npm bin)/ts-node\" ./server/server.ts || npm run build",

这是我的ts-loader

{ test: /\.tsx?$/, loader: 'awesome-typescript-loader' }

和我的开发服务器配置

if (NODE_ENV === 'development') {
  let webpack = require('webpack')
  const webpackConfig = require('../webpack.config')
  const compiler = webpack(webpackConfig)

  app.use(require('webpack-dev-middleware')(compiler, {
    noInfo: true, publicPath: webpackConfig.output.publicPath
  }))
  app.use(require('webpack-hot-middleware')(compiler))
}

我无法克服错误

[HMR] The following modules couldn't be hot updated: (Full reload needed)
This is usually because the modules which have changed (and their parents) do not know how to hot reload themselves. See http://webpack.github.io/docs/hot-module-replacement-with-webpack.html for more details.

有同样的问题,并通过添加修复它react-hot-loader,可以使用安装npm install --save-dev react-hot-loader.

你的配置应该是这样的:

{ test: /\.tsx?$/, loaders:['react-hot', 'awesome-typescript-loader'] }
