🏗️ Monorepo Architecture

DFD is structured as an NPM Workspace Monorepo, decoupling the presentation layer from the secure data pipeline.

DFDWebsite/
├── client/           # Frontend: Next.js 15 (App Router), Tailwind, Framer Motion
├── server/           # Backend: Express.js, Prisma ORM, JWT, WhatsApp-Web.js
└── shared/           # Core library: Shared Zod schemas and TypeScript interfaces

The Data Flow

1. Edge Delivery: Vercel serves the heavily-cached React frontend to the client.
2. Type-Safe Ingress: HTTP Requests hit the Railway-hosted Express server. Routes instantly validate payloads against the exact same Zod schemas compiled in the shared workspace.
3. Deep Processing: Express executes business logic and interfaces with the Aiven MySQL database via Prisma ORM.

🔒 Security Hardening

• Zod Strict Validation: Absolutely no data touches the controllers without passing rigorous Zod type-checking.
• Encrypted State: Admin sessions rely on hardened, HttpOnly, Secure, SameSite=Strict cookies.
• Audit Logging: Mutative actions within the dashboard are tracked and stamped in an immutable AuditLog table.
• WhatsApp Defense: Client tracking dashboards are secured behind an involuntary 2FA WhatsApp lock to mask PII.

💻 Local Developer Setup

To run this platform locally, follow these strict execution bounds.

1. Install Dependencies

Initialize the monorepo from the root directory to link the workspaces.

npm install

2. Environment Variables

You must inject .env files into both the client/ and server/ directories.

client/.env

NEXT_PUBLIC_API_URL=http://localhost:5000/api/v1

server/.env

PORT=5000
DATABASE_URL="mysql://user:pass@host:port/db"
JWT_SECRET="your_secure_secret"
CLOUDINARY_URL="cloudinary://..."

3. Build the Shared Workspace (Critical)

The server cannot boot unless it has native local access to the compiled shared logic.

cd shared
npm run build

4. Ignite the Servers

Boot the backend API:

cd server
npx prisma generate
npx prisma db push
npm run dev

Boot the frontend React interface:

cd client
npm run dev
