Most Next js devs don't know about this Cloudflare bug — I lost a full day to it

Next.js app not loading on Cloudflare? Rocket Loader silently breaks Next.js hydration in production — yahan hai full fix in 30 seconds.

Mere saath kya hua:
✅ Dev me sab fine — prod me frontend updated code dikha hi nahi raha tha
✅ Browser DevTools → Network tab → JS files cancelled, no console error
✅ Culprit: Cloudflare Rocket Loader (default ON in many CF accounts after free plan setup)
✅ Fix: Cloudflare Dashboard → Speed → Optimization → Rocket Loader → OFF
✅ Alternate: per-script attribute data-cfasync="false" — selective opt-out

The deep reason: Rocket Loader har script tag ko intercept karta hai aur apne async loader ke through inject karta hai. Next.js hydration relies on script execution order — RL randomizes that order, hydration mismatch hota hai, aur app silently degrades. Most dangerous bug type: koi error nahi, sirf "kinda works" mode.

Jab everyone Gemini 3.5, Google Antigravity, aur agent stacks launch kar raha hai — adhe production-killing bugs abhi bhi infra config gotchas hain. Real engineering ≠ vibe coding.

🛠️ Casagbic — AI coding agent platform, built from scratch. Devin-style autonomy without the price tag. Launching soon. Follow before it drops.
