Building a 9-Language Fan Site with Next.js 15 and next-intl (No Middleware)

I recently built a multilingual fan site for The Duskbloods, an upcoming FromSoftware game. The challenge: 9 languages (English, Japanese, Korean, Chinese, Spanish, French, German, Italian, Portuguese), static generation, and no middleware — all deployed on Cloudflare Workers.

Here's how I did it and what I learned.

The Architecture

The site uses Next.js 15 App Router with next-intl v4 for internationalization. The key constraint: I wanted to avoid middleware to keep Cloudflare Worker costs down.
