用webpack
的热加载文件在刚开始没几个的时候就快,但是加多了几个文件就变的很慢的,
随便改一个字都要6、7秒才能更新到
这是怎么回事?
这是我的启动dev-server
var path = require('path');
var fs = require('fs');
var express = require('express');
var webpack = require('webpack');
var routes = require('./router/index');
var config = require('./config');
var http = require('http');
var bodyParser = require('body-parser');
var compression = require('compression');
var consolidate = require('consolidate');
var webpackConfig = require('./webpack.dev.conf');
//端口
var port = process.env.PORT || config.dev.port;
var app = express();
//bodyparser 这个设置要放路由前原因:(http://blog.csdn.net/u013438638/article/details/48953143)
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.engine('html', consolidate.ejs);
app.set('views', path.resolve(__dirname, 'views'));
app.set('view engine','html');
app.use(compression()); //开启 gzip
//webpack编译器
var compiler = webpack(webpackConfig);
//webpack-dev-server 中间件
var devMiddleware = require('webpack-dev-middleware')(compiler, {
publicPath: webpackConfig.output.publicPath,
stats: {
colors: true,
chunks: false
}
});
//热更新中间件
var hotMiddleware = require('webpack-hot-middleware')(compiler);
app.use(devMiddleware);
app.use(hotMiddleware);
//具体路由action
routes(app);

樓主的問題之前遇到過,是因為babel-loader
编译了第三方类库导致的,我看了楼主已经exclude
了,建议楼主用下 webpack-bundle-analyzer
,生成分析圖看下是不是編譯了哪些不需要便衣隊第三方的庫
