我一直在做一个项目,确信HMR正常工作,如果我更新任何 .js 文件,webpack就会编译模块并进行热替换。
我正在处理一个 .vue 文件,webpack 会重新编译,但是没有全新的 HMR。
希望有人能看一下并告诉我是否有问题:
我在 cli 中使用的脚本如下:
webpack-dev-server --d --watch --output-path ./public --config ./_src/webpack.config.js --progress --env.dev
我想最重要的部分是这个:
devServer: {
contentBase: 'public',
hot: true,
filename: 'main.js',
overlay: true,
stats: { colors: true },
port: 3000,
proxy: {
'/': {
target: 'http://moment.local/',
secure: false,
changeOrigin: true
}
},
historyApiFallback: true
},
但是如果有帮助的话,下面是我的整个配置文件。
const webpack = require('webpack')
const {resolve} = require('path')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
module.exports = env => {
const addPlugin = (add, plugin) => add ? plugin : undefined
const ifProd = plugin => addPlugin(env.prod, plugin)
const removeEmpty = array => array.filter(i => !!i)
// Our Sass Extraction Plugin
const extractSass = new ExtractTextPlugin({
filename: 'style.css',
disable: env.dev
})
return {
entry: {
'vendor': ['jquery', 'KlaviyoSubscribe', 'learnq', 'select2', 'slick-carousel', 'moment', 'lodash'],
'main': resolve(__dirname, './js/index.js')
},
output: {
filename: '[name].js',
path: resolve(__dirname, '../public/'),
pathinfo: !env.prod
},
module: {
loaders: [
{
test: /\.vue$/,
loader: 'vue-loader',
options: {
loaders: {
css: 'vue-style-loader!css-loader!postcss-loader!sass-loader', // <style lang='scss'>
scss: 'vue-style-loader!css-loader!postcss-loader!sass-loader', // <style lang='scss'>
sass: 'vue-style-loader!css-loader!postcss-loader!sass-loader?indentedSyntax' // <style lang='sass'>
}
}
},
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{ test: /\.s(c|a)ss$/,
use: extractSass.extract({
fallback: 'style-loader',
use: [
{
loader: 'css-loader',
options: {
importLoaders: 1,
sourceMap: true
}
},
'postcss-loader?sourceMap',
'sass-loader?sourceMap'
]
})
},
{
test: /\.(png|jpg|gif|svg)$/,
loader: 'file-loader',
options: {
name: '[name].[ext]?[hash]'
}
}
]
},
devtool: env.prod ? 'source-map' : 'eval',
devServer: {
contentBase: 'public',
hot: true,
filename: 'main.js',
overlay: true,
stats: { colors: true },
port: 3000,
proxy: {
'/': {
target: 'http://moment.local/',
secure: false,
changeOrigin: true
}
},
historyApiFallback: true
},
bail: env.prod, // Fail out on the first error if production
resolve: {
alias: {
'vue$': 'vue/dist/vue.common.js'
}
},
plugins: removeEmpty([
extractSass,
new webpack.HotModuleReplacementPlugin(),
new webpack.optimize.CommonsChunkPlugin({
// Let's create js for our vendor scripts
name: 'vendor',
// (with more entries, this ensures that no other module
// goes into the vendor chunk)
minChunks: Infinity
}),
new webpack.optimize.CommonsChunkPlugin({
name: 'commons',
filename: 'commons.js',
// (Modules must be shared between 2 entries)
minChunks: 2
})
...
])
}
}
我在这方面确实有些困难,所以任何帮助都将是非常好的。
