What is this?
Production optimization minifies assets, enables compression, sets cache busting, and strips dev markup.
Why should you care?
MarkupVerse production HTML drops source maps from public and hashes filenames.
See it live — copy this example
Save as demo.html and open in your browser, or use Run Example below.
<head>
<link rel="stylesheet" href="/css/app.a3f9c2.css">
<script src="/js/app.9b1e4d.js" defer></script>
</head>
<body>
<!-- prod: no dev comments -->
<main id="app"></main>
</body>Run Example »
Edit the code below and click Run to see the result in Toolliyo’s live editor.
What happened?
- Fingerprinted filenames = long cache.
- Brotli/gzip on server.
- Remove console.log and HTML comments.
Practice next
- Hash CSS/JS filenames.
- Enable compression on host.
- Strip dev comments.
- Add source maps private only.
- Set immutable cache on /css/*.hash.css.
Remember
Hashed assets. Compression on. Clean prod HTML.
MarkupVerse prod bundle
Build pipeline emits hashed assets.
Outcome: Repeat visitors load cached JS instantly.
