DOOM INDEX is a Cloudflare-first generative art project. It turns live crypto market context into paintings, stores the resulting image on Arweave via ArDrive Turbo during recurring generation, and uploads the framed GLB plus NFT metadata only when a mint happens. D1 indexes the artwork and caches mint-time GLB refs for the web UI, archive, OGP, and mint flow.

• Frontend: Next.js 16 App Router
• Runtime: Cloudflare Workers via OpenNext
• Storage: Arweave for artwork assets, D1 for searchable metadata
• Generation inputs: CoinGecko, Fear & Greed, Tavily, Runware
• Minting: custom Doom NFT program on Solana

Install dependencies:

bun install

Copy .example.vars to .dev.vars, then fill in the required values:

cp .example.vars .dev.vars

Minimum local env:

NEXT_PUBLIC_BASE_URL=http://localhost:8787 RUNWARE_API_KEY=your_runware_api_key ARDRIVE_TURBO_SECRET_KEY='{"kty":"RSA", ...}'

Common optional env:

COINGECKO_API_KEY=your_coingecko_api_key TAVILY_API_KEY=your_tavily_api_key ARWEAVE_GATEWAY_BASE_URL=https://permagate.io

bun run dev uses Next.js' native .env.local loading. Point .env.local at .dev.vars so Next.js and the Bun scripts share the same values:

ln -s .dev.vars .env.local

Run the Next.js app:

bun run dev

Run the Cloudflare preview build:

bun run build:cf bun run preview

Trigger the cron loop locally:

bun run watch-cron

Generate a painting locally:

bun run generate

Generate the framed GLB directly:

bun run generate:framed-glb --image ./out/example.webp --out ./out/framed.glb

Upload an explicit image + GLB bundle to Arweave:

bun --env-file=.dev.vars scripts/upload-metadata-ardrive.ts \ --token-id 1 \ --thumbnail ./out/example.webp \ --glb ./out/framed.glb

Upload the built-in placeholder fixture bundle:

bun --env-file=.dev.vars scripts/upload-metadata-ardrive.ts \ --token-id 1 \ --fixture

Generate and apply Drizzle migrations:

bun run db:generate bun run db:migrate

Production migration and deployment commands:

bun run db:migrate:prod bun run deploy

bun run lint bun run typecheck bun run test

Focused test commands:

bun run test:unit bun run test:integration
