我在React中实际提供我的bundle.js文件的gzip压缩时遇到了麻烦。我试图大幅度减小这个尺寸,我已经完成了uglify和重复数据删除等等......它从2.9mb下降到2.6mb这对我来说真的很奇怪。我现在使用压缩插件,我得到一个输出的gzip文件,但现在我仍在服务bundle.js而不是bundle.js.gz。
我不想使用express中的压缩中间件,因为我在构建过程中使用gzip。无论如何,这是我的distServer文件:
import express from 'express';
import path from 'path';
import open from 'open';
/* eslint-disable no-console */
const port = process.env.PORT || 3000;
const app = express();
app.use(express.static('dist'));
app.get('*.js', function(req, res, next) {
req.url = req.url + '.gz';
res.set('Content-Encoding', 'gzip');
res.set('Content-Type', 'text/javascript');
next();
});
app.get('*.css', function(req, res, next) {
req.url = req.url + '.gz';
res.set('Content-Encoding', 'gzip');
res.set('Content-Type', 'text/css');
next();
});
app.get('*', function(req, res) {
res.sendFile(path.join( __dirname, '../dist/index.html'));
});
app.listen(port, function(err) {
if (err) {
console.log(err);
} else {
open(`http://localhost:${port}`);
}
});
我的webpack配置是:
import webpack from 'webpack';
import path from 'path';
import ExtractTextPlugin from 'extract-text-webpack-plugin';
var CopyWebpackPlugin = require('copy-webpack-plugin');
var CompressionPlugin = require("compression-webpack-plugin");
var BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
export default {
devtool: 'source-map',
noInfo: false,
entry: [
'./src/index'
],
target: 'web',
output: {
path: __dirname + '/dist', // Note: Physical files are only output by the production build task `npm run build`.
publicPath: '/',
filename: 'bundle.js'
},
plugins: [
// new BundleAnalyzerPlugin(),
new webpack.optimize.OccurenceOrderPlugin(),
new webpack.DefinePlugin({
'process.env': {NODE_ENV: '"production"'}
}),
new ExtractTextPlugin('styles.css'),
new webpack.optimize.DedupePlugin(),
new webpack.optimize.UglifyJsPlugin({
mangle: true,
compress: {
warnings: false, // Suppress uglification warnings
pure_getters: true,
unsafe: true,
unsafe_comps: true,
screw_ie8: true
},
output: {
comments: false,
},
exclude: [/\.min\.js$/gi] // skip pre-minified libs
}),
new CopyWebpackPlugin([
{ from: 'src/robots.txt', to: 'robots.txt' },
{ from: 'src/sitemap.xml', to: 'sitemap.xml' }
], {
copyUnmodified: true
}),
new webpack.IgnorePlugin(/^\.\/locale$/, [/moment$/]),
new CompressionPlugin({
asset: "[path].gz[query]",
algorithm: "gzip",
test: /\.js$|\.css$|\.html$/,
threshold: 10240,
minRatio: 0
})
],
module: {
loaders: [
{test: /\.js$/, include: path.join(__dirname, 'src'), loaders: ['babel']},
{test: /(\.css)$/, loader: ExtractTextPlugin.extract("css?sourceMap")},
{test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, loader: 'file'},
{test: /\.(woff|woff2)$/, loader: 'url?prefix=font/&limit=5000'},
{test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=application/octet-stream'},
{test: /\.(jpe?g|png|gif|svg)$/i, loader: "url?limit=10000"},
{test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: 'url?limit=10000&mimetype=image/svg+xml'},
{
test: /favicon\.ico$/,
loader: 'url',
query: {
limit: 1,
name: '[name].[ext]',
},
}
]
}
};
我认为app.get函数会根据需要引入这些gzip文件,但我可能会错过一步?另外,在我的index.html文件中,是否需要省略一起引入捆绑文件的脚本标记?
任何指导和想法都将不胜感激!

听起来您首先要验证您是否正在提供gzip压缩文件,这可以通过Chrome DevTools轻松完成。
打开Chrome DevTools,转到performance
标签并查看您的网站。加载后,检查网络请求部分,找到要验证的Javascript文件正在被gzip压缩。如果操作正确,您将看到something like this,其中encoded data
是通过线路发送的(希望压缩的)数据的大小,decoded body
是未压缩数据的大小。
如果两者相等,那么你可以正确地进行gzipping,但不能发送它。
我建议您在反向代理级别处理此问题,理想情况下使用NGINX gzip static module来处理gzip压缩文件。你真的应该使用NGINX来提供静态内容,因为它会占用你的节点服务器。

您应该将静态列表放在中间件
之后import express from 'express';
import path from 'path';
import open from 'open';
/* eslint-disable no-console */
const port = process.env.PORT || 3000;
const app = express();
app.get('*.js', function(req, res, next) {
req.url = req.url + '.gz';
res.set('Content-Encoding', 'gzip');
res.set('Content-Type', 'text/javascript');
next();
});
app.get('*.css', function(req, res, next) {
req.url = req.url + '.gz';
res.set('Content-Encoding', 'gzip');
res.set('Content-Type', 'text/css');
next();
});
app.use(express.static('dist'));
app.get('*', function(req, res) {
res.sendFile(path.join( __dirname, '../dist/index.html'));
});
app.listen(port, function(err) {
if (err) {
console.log(err);
} else {
open(`http://localhost:${port}`);
}
});
