我在使用反应无状态函数进行热重新加载webpack-dev-middleware时遇到了一些麻烦,但如果我创建一个类扩展组件,则工作正常.
例如,这非常有效.
// home.js
import React from 'react'
export default class Home extends React.Component {
render() {
return (
<div>
<h1>Drop it like it's hot</h1>
</div>
)
}
}
然而,这失败了.
// home.js
import React from 'react'
export default function Home() {
return (
<div>
<h1>Hello World</h1>
</div>
)
}
错误:
[Warning] [HMR] The following modules couldn't be hot updated: (Full reload needed) (bundle.js, line 1742)
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.
[Warning] [HMR] - ./client/components/home.js (bundle.js, line 1750)
最佳答案 如果它仍然相关并且人们还有问题,那么有一种方法,版本3仍然在开发中.我将在这里粘贴我的package.json和webpack.config.js文件的设置,但如果你想要一个工作示例
here is the repo I created for this

webpack.config.js
const webpack = require('webpack');
module.exports = {
entry: [
'react-hot-loader/patch',
'webpack-dev-server/client?http://localhost:8080',
'webpack/hot/only-dev-server',
'./src/index.js'

module: {

您可以使用我创建的repo作为样板,并在生产时升级react-hot-loader版本.干杯.
