我有一個簡單的配置webpack-dev-middleware
和webpack-hot-middleware
使用熱重載(HMR)的反應。Webpack開發中間件反應熱重載太慢
一切都工作正常,除了我對代碼所做的每一個變化,它需要2 3-4秒!直到我在瀏覽器中看到它。 我做錯了什麼?它應該是這樣的?
我的代碼相當大,我的包縮小到841kb(200kb gzipped)是這個原因嗎?代碼庫越大,創建的包越慢?
Express服務器:
var webpack = require('webpack');
var webpackConfig = require('./webpack.hot.config');
var compiler = webpack(webpackConfig);
app.use(require("webpack-dev-middleware")(compiler, {
noInfo: true,
publicPath: webpackConfig.output.publicPath,
watchOptions: {
poll: true
}
}));
app.use(require("webpack-hot-middleware")(compiler, {
log: console.log,
path: '/__webpack_hmr',
heartbeat: 10 * 1000
}));
webpack.hot.config.js
const path = require('path');
const webpack = require('webpack');
module.exports = {
context: __dirname,
entry: [
'webpack-hot-middleware/client?path=/__webpack_hmr&timeout=20000',
'./src/js/index'
],
module: {
loaders: [{
test: /\.jsx?$/,
include: path.join(__dirname, 'src/js'),
//exclude: /node_modules/,
loader: 'react-hot!babel'
},
{
// Test expects a RegExp! Note the slashes!
test: /\.css$/,
loaders: ['style', 'css'],
// Include accepts either a path or an array of paths.
include: path.join(__dirname, 'src/css')
}
]
},
resolve: {
extensions: ['', '.js', '.jsx']
},
output: {
path: __dirname + '/public',
publicPath: '/',
filename: 'js/app.js'
},
plugins: [
new webpack.optimize.OccurenceOrderPlugin(),
new webpack.HotModuleReplacementPlugin(),
new webpack.NoErrorsPlugin()
]
};
而這正是我在控制檯中時,我的代碼改變的東西:
[HMR] App is up to date.
app.js:73223 [HMR] bundle rebuilding
app.js:73226 [HMR] bundle rebuilt in 335ms
app.js:73289 [HMR] Checking for updates on the server...
app.js:73362 [HMR] Updated modules:
app.js:73364 [HMR] - ./src/js/components/header.jsx
app.js:73369 [HMR] App is up to date.
所以'排除:/ node_modules /'被註釋掉。當它在配置中時,構建是否仍然很慢?除此之外,我建議刪除OccurrenceOrderPlugin。這個插件是爲了幫助分塊,它看起來並不像你正在實現的(除非你在不同的配置文件中)。 – garrettmaring
@garrettmaring,使用'include'代替'exclude'應該足夠了,因爲它是更明確的變體。在過去,我認爲我還需要使用'OccurenceOrderPlugin'來確保'webpack-dev-middleware'的熱重載。 –
