Converting a GitHub Raw File URL to a jsDelivr CDN URL

Original URL

The original file was hosted on GitHub using the raw content URL format:

https://raw.githubusercontent.com/Neurotech-HQ/js-workers/refs/heads/main/build/pdf.worker.5.1.91.mjs

This format directly fetches the raw file from the GitHub repository. However, it is not optimized for CDN delivery and may suffer from slower performance or rate limits under heavy traffic.

---

Goal

Convert the GitHub raw link into a CDN-compatible URL using jsDelivr, which provides:

• Global CDN delivery
• Better performance
• Version locking support
• Easy integration with web apps

---

jsDelivr CDN URL Format

The general format for jsDelivr GitHub CDN links is:

https://cdn.jsdelivr.net/gh/{USER}/{REPO}@{TAG_OR_BRANCH}/{FILE_PATH}

---

Conversion Steps

Step 1: Extract Components

From the original URL:

• User: Neurotech-HQ
• Repo: js-workers
• Branch: main
• File path: build/pdf.worker.5.1.91.mjs

Step 2: Construct jsDelivr URL

Combine the components using jsDelivr format:

https://cdn.jsdelivr.net/gh/Neurotech-HQ/js-workers@main/build/pdf.worker.5.1.91.mjs

✅ refs/heads/main becomes @main

---

Final CDN URL

https://cdn.jsdelivr.net/gh/Neurotech-HQ/js-workers@main/build/pdf.worker.5.1.91.mjs

---

Notes

• You can replace @main with a specific tag or commit SHA to lock the version and ensure stability.
• jsDelivr automatically caches files for better performance, but this may delay updates after a push.
• Consider adding a fallback strategy in production for better reliability.
