如何在express中壓縮fs.createReadStream

Question

我有這段代碼;

const express = require('express') 
const compression = require('compression') 
const app = express() 
const fs = require('fs'); 
const path = require('path'); 
const port = process.env.PORT || 3003; 

app.use(compression()) 
app.use('/public', express.static('public')); 

app.get('/', (req, res) => { 
    fs.createReadStream(__dirname + '/public/src/index/index.html').pipe(res); 
}); 

app.listen(port,() => { 
    console.log(`Portfolio listening on port ${port}`) 
}) 

在鉻開發工具被請求在index.html的app.js文件gzip壓縮，但該第一文件（index.html在上面的代碼稱爲）不是。

如何在流式傳輸之前壓縮index.html文件？

如何使用zlib模塊：

fs.createReadStream(__dirname + '/public/src/index/index.html') 
    .pipe(zlib.createGzip()) 
    .pipe(res);
