webpack 热更新 只对改变 CSS 有效 改变 HTML 页面会刷新 没用其他框架。
写了一个很简单的demo，HMR 开启成功，但是只对改变 CSS 有效，改变 HTML 只会刷新页面，没有达到热替换的效果。
global webpack version 3.3.0
Mac OS 10.11.6
this is my package.json file:
{
"name": "demo-hmr",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "webpack-dev-server --hot --inline webpack.config.js"
},
"keywords": [],
"author": "",
"license": "MIT",
"dependencies": {
"babel-core": "^6.26.0",
"babel-loader": "^7.1.2",
"babel-preset-env": "^1.6.0",
"css-loader": "^0.28.7",
"style-loader": "^0.18.2",
"webpack": "^3.5.6",
"webpack-dev-server": "^2.7.1"
}
}this is my webpack.config.js file:
module.exports = {
entry: './main.js',
output: {
filename: 'bundle.js'
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader'
}
},
{
test: /\.css$/,
use: [
'style-loader',
'css-loader'
]
}
]
}
}this is my main.js file:
I change dom in this file, just change innerHTML of divv, then page will refresh, not i want for.
import app from './app.css'
var divv = document.createElement('div')
divv.innerHTML = "Hello webpack"
document.body.appendChild(divv)this is my app.css file:
body {
background-color: yellow;
}this is my index.html file:
<html>
<body>
<h1>Hello World!</h1>
<script type="text/javascript" src="bundle.js"></script>
</body>
</html>如果你对这篇内容有疑问，欢迎到本站社区发帖提问 参与讨论，获取更多帮助，或者扫码二维码加入 Web 技术交流群。

HTML不会热更新。只有js，css这些被webpack管理的模块化东西才会热更新。
是没配置html的loader吧，像这样：
