如果你设置hot: true
in the devServer
设置在Webpack,那么模块热更换CSS 有效,并且无需重新加载完整页面即可应用更改。但是当改变HTML文件时,实时重载由于某种原因不起作用,您需要手动刷新页面才能应用更改。
If hot: true
被禁用于devServer
配置文件,然后更改 HTML 文件时实时重载工作正常,页面会自行重新加载,但是模块热更换因为 CSS 不起作用,当更改 CSS 时,页面会完全重新加载。
这是应该的方式吗?为什么会发生这种情况,我该如何启用模块热更换对于CSS,但同时使实时重载更改 HTML 文件时有效吗?
为了创建许多 HTML 文件,我使用HtmlWebpackPlugin
plugin.
以下是配置文件:
webpack.common.js
const path = require('path');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CopyPlugin = require('copy-webpack-plugin');
const webpack = require('webpack');
module.exports = mode => {
const PRODUCTION = mode === 'production';
return {
entry: {
app: './src/index.js',
},
output: {
filename: 'js/[name].bundle.js',
path: path.resolve(__dirname, 'dist'),
publicPath: '/',
},
module: {
rules: [
{
test: /\.(png|jpe?g|gif|svg)$/i,
use: [
{
loader: 'file-loader',
options: {
name: 'img/[path][name].[ext]',
outputPath: 'img',
},
},
],
},
],
},
plugins: [
new CleanWebpackPlugin(),
new HtmlWebpackPlugin({
hash: false,
template: 'src/index.html',
filename: 'index.html',
}),
new webpack.DefinePlugin({
PRODUCTION: PRODUCTION,
}),
new CopyPlugin([
{ from: 'src/img', to: 'img' },
{ from: 'src/fonts', to: 'fonts' },
]),
],
}
};
webpack.dev.js
const merge = require('webpack-merge');
const common = require('./webpack.common.js');
const webpack = require('webpack');
module.exports = (env, argv) => {
return merge(common(argv.mode), {
devtool: 'inline-source-map',
devServer: {
contentBase: './dist',
overlay: {
warnings: true,
errors: true
},
port: 8081,
hot: true,
},
watchOptions: {
aggregateTimeout: 100,
},
module: {
rules: [
{
test: /\.s[ac]ss$/i,
use: [
'style-loader',
{
loader: 'css-loader',
options: {
sourceMap: true,
},
},
{
loader: 'sass-loader',
options: {
sourceMap: true,
},
},
],
},
{
test: /\.css$/i,
use: [
'style-loader',
'css-loader',
],
}
],
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
],
});
};
