Support This Project

Stack

• Framework: Next.js 15 App Router, TypeScript
• Styling: Tailwind CSS 4, shadcn/ui, Geist font
• Auth: NextAuth.js (credentials)
• ORM/DB: Prisma + SQLite (file-based, easily swap to other drivers)
• State & Forms: React Hook Form, Zod, TanStack Query
• Email: Resend or SMTP (optional via env)

Getting Started

1. Install dependencies

   npm install

2. Environment variables

   • Copy .env.example to .env and adjust values (set NEXTAUTH_SECRET, update store identity, etc.).
   • DATABASE_URL defaults to file:./dev.db, which lives inside the prisma directory.

Environment configuration

Create a .env file in the project root using values that match your stack. The snippet below mirrors a local SQLite setup with optional payment and storage providers disabled by default:

DATABASE_URL="file:./prisma/dev.db"
NEXTAUTH_SECRET="change-me"

# Branding
STORE_NAME="Digital Goods Store"
STORE_CONTACT_EMAIL="hello@store.test"

# Storage (leave empty for local filesystem fallback)
STORAGE_PROVIDER="local"
STORAGE_BASE_URL=""
STORAGE_BUCKET=""

# Download policy overrides
DOWNLOAD_EXPIRY_HOURS="72"
DOWNLOAD_MAX_COUNT="3"

# Optional email providers
RESEND_API_KEY=""
SMTP_URL=""

# Payment gateways (populate when integrating)
STRIPE_SECRET_KEY=""
MIDTRANS_SERVER_KEY=""
MIDTRANS_CLIENT_KEY=""
MIDTRANS_MERCHANT_ID=""
XENDIT_API_KEY=""
DUITKU_MERCHANT_CODE=""
DUITKU_API_KEY=""

# Auto QRIS worker (optional)
AUTOQRIS_WORKER_URL=""
AUTOQRIS_API_KEY=""
AUTOQRIS_STATIC_QRIS=""

# Cloudflare R2 (optional)
R2_ACCOUNT_ID=""
R2_ACCESS_KEY_ID=""
R2_SECRET_ACCESS_KEY=""
R2_BUCKET=""
R2_PUBLIC_BASE_URL=""

3. Initialize the database

   • Apply the schema to SQLite using the provided migration SQL:

     mkdir -p prisma
     sqlite3 prisma/dev.db < prisma/migrations/0001_init/migration.sql

   • Seed demo data (admin user + sample products):

     npm run db:seed

     Default admin credentials: admin@demo.test / Admin123!

4. Run the development server

   npm run dev

   Visit http://localhost:3000 to explore the storefront. Admin routes live under /admin and require sign-in.

Available Scripts

Command	Description
npm run dev	Start local development server
npm run build	Build for production
npm run start	Start the production server
npm run lint	Run ESLint
npm run db:seed	Seed database with demo admin and products
npm run db:migrate:d1	Generate SQL script for Cloudflare D1 migration

Features Snapshot

• Storefront: search & tag filters, markdown product detail modal, checkout sheet integrated with active gateway configuration.
• Checkout Flow: creates orders, returns gateway instructions or redirect URLs (Stripe / Midtrans / Xendit / Duitku / Manual QRIS / Auto QRIS), issues download tokens on successful payment.
• Secure Downloads: /api/download/:token enforces expiry & quota, with optional Cloudflare R2 signed URLs or custom storage domains.
• Admin Console: dashboard metrics, order table + detail view (manual status updates & email resend), product CRUD (with file pointers), settings management for payment/storage/policies.
• Webhooks: Stripe, Midtrans, Xendit, and Duitku handlers map gateway payloads to unified order updates. Auto QRIS polling endpoint verifies payments against detected push notifications.

Testing & QA Notes

• Run npm run lint before committing changes.
• The project ships with sample products and an admin user via the seed script to accelerate manual QA.
• Webhook endpoints expect verified signatures in production. Current implementation focuses on payload handling; plug in verification when wiring to live gateways.

Deployment Tips

• Swap DATABASE_URL to your production database (SQLite, Postgres, etc.) and re-run migrations.
• Configure environment variables for the selected payment gateway, object storage, and email provider. For Duitku supply DUITKU_MERCHANT_CODE / DUITKU_API_KEY (and optionally DUITKU_BASE_URL). For Auto QRIS set AUTOQRIS_WORKER_URL, AUTOQRIS_API_KEY, AUTOQRIS_STATIC_QRIS, and AUTOQRIS_CALLBACK_URL (optional). To use Cloudflare R2 signed links, provide R2_ACCOUNT_ID, R2_ACCESS_KEY_ID, R2_SECRET_ACCESS_KEY, and R2_BUCKET (or R2_PUBLIC_BASE_URL if serving files via a public domain) and set the storage provider to R2 in the admin settings.
• next.config.ts sets images.unoptimized = true to support arbitrary remote assets (QR codes, marketing images). Adjust as needed for production CDN setups.
• Remember to update APP_BASE_URL to the deployed origin so receipt emails contain valid download links.
• To target Cloudflare D1, run npm run db:migrate:d1 to emit prisma/d1-migration.sql, then apply it with wrangler d1 execute <DB_NAME> --remote --file prisma/d1-migration.sql.
