Infrastructure / Cloudflare

Static docs at the edge. Prices straight from the book.

Nexwest Docs is built for Cloudflare Workers with OpenNext. The docs are prerendered, and the live market ticker connects directly from the browser to the market data feed — no Worker in the data path.

Docs at the edge

100+ prerendered pages, static assets, global cache. No database or runtime content dependency.

Prices in the browser

The ticker connects to the market feed directly. Cloudflare serves the page; it does not relay every tick.

Relay only if needed

Use a Worker + Durable Object per market when you need normalization, auth, or fan-out.

01 / Build

Deploy the docs

The project includes wrangler.jsonc and open-next.config.ts. Next.js 16.4.5 is supported by @opennextjs/cloudflare 1.20.16. The SSG site uses the Workers Static Assets incremental cache, so no R2 bucket, D1 database, or queue is required.

code

# Build the Cloudflare Worker bundle
npm run build:cf

# Preview locally with workerd
npm run preview

# Deploy to your Cloudflare account
npm run deploy

code

  "name": "nexwest-docs",

Windows note: both the OpenNext build and the Wrangler preview completed on Windows. WSL remains recommended for production deploys.

02 / Real-time

Where Workers fit

Browser ── WSS ────────────────► Market data feed
   │
   └── HTTPS ──► Cloudflare Worker ──► Static docs / HTML

Optional relay:
Browser ── WSS ──► Worker /ws ──► Durable Object per market
                                      └── outbound WSS ──► Venue

Recommended

Direct WebSocket

Lowest latency, no per-message Worker cost, and no extra point of failure. Set NEXT_PUBLIC_MARKET_WS_URL to point the ticker at the Nexwest feed.

Optional

Worker + Durable Object

Use one Durable Object per market to hold the upstream connection and fan out. Outbound WebSockets prevent hibernation, so budget for duration and reconnect logic.

03 / Configuration

Environment

Variable	Purpose
`NEXT_PUBLIC_SITE_URL`	Canonical origin for metadata, sitemap, and AI files
`NEXT_PUBLIC_APP_URL`	Trading app origin for the Launch app button
`NEXT_PUBLIC_MARKET_WS_URL`	WebSocket URL for the live ticker; unset uses the demo feed
