Diátaxis: how-to

Snack Lab is a small Next.js storefront deployed to Cloudflare Workers with OpenNext. It uses:

• KV for products, orders, and item requests
• R2 for uploaded product images
• HTTP-only cookie auth for the admin area

Install dependencies:

npm clean-install

Create a local Cloudflare vars file for development:

cp .dev.vars.example .dev.vars

Then set your existing admin password in .dev.vars:

ADMIN_PASSWORD=your-existing-password

Start the app:

npm run dev

In the Cloudflare dashboard, use these commands:

• Build command: npx opennextjs-cloudflare build
• Deploy command: npx wrangler deploy
• Non-production branch deploy command: npx wrangler versions upload

Before deploying, store the admin password as a Wrangler secret:

npx wrangler secret put ADMIN_PASSWORD

Use the same password value you already use if you are not rotating it yet.

wrangler.toml expects these bindings:

• STORE_KV → KV namespace
• STORE_R2 → R2 bucket
• ADMIN_PASSWORD → Wrangler secret

npm run dev
npm run build
npm run preview
npm run deploy
npm run lint

• Public storefront with stock-aware cart limits
