⚡ Deployment: Vercel & Production

Deploying an instance of AI Social Post Generator to the web requires minimal configuration. The architecture is engineered explicitly for Vercel serverless environments.

One-Click Deploy

Pro Tip: Fork this repository, replace YOUR_GITHUB_USER in the link above, to streamline deployments for your private forks.

🔑 Required Environment Variables

To successfully deploy and run, you must populate the following environment variables in your Vercel project settings:

Service	Variable	Description & Source
Database	DATABASE_URL	PostgreSQL connection string (Supabase shared pool with pgbouncer)
	DIRECT_URL	Direct DB connection for Prisma migrations and pushes
NextAuth / Google	NEXTAUTH_SECRET	Secure random string generated via openssl rand -base64 32
	NEXTAUTH_URL	Your production domain (e.g. https://social-post-woad.vercel.app)
	GOOGLE_CLIENT_ID	Get from Google Cloud Console
	GOOGLE_CLIENT_SECRET	Get from Google Cloud Console
Stripe Billing	STRIPE_SECRET_KEY	Get from Stripe Dashboard
	NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY	Get from Stripe Dashboard
	STRIPE_WEBHOOK_SECRET	Webhook secret for resolving credit purchases
AI Generator	MU_API_KEY	Create an account and get key from muapi.ai/access-keys
	WEBHOOK_URL	Callback URL for receiving slow-running generation events

🚀 Launching on Vercel: Step-by-Step

1. Database Provisioning: Create a new Postgres database (via completely free tiers on Vercel Postgres, Supabase, or Neon). Retrieve the pooling connection string (DATABASE_URL) and direct connection string (DIRECT_URL).
2. Project Creation: Import your GitHub fork into the Vercel dashboard.
3. Configure Environment Variables: Copy the variables above into the Vercel project settings environment tab.
4. Deploy: Hit "Deploy". Vercel will automatically run the build steps (npm run build).
5. Database Push: Since Prisma does not automatically migrate via Vercel builds by default, you may want to append npx prisma db push && to your Vercel build command, or manually run it locally pointing to your production database URL.
6. Integrations Setup:
   • Establish a Google Cloud OAuth app, enabling the callback URL: https://social-post-woad.vercel.app/api/auth/callback/google
   • Setup a Stripe Webhook, pointing to https://social-post-woad.vercel.app/api/stripe/webhook and selecting the checkout.session.completed event to grab your webhook signing secret.

git clone https://github.com/SamurAIGPT/social-post
cd social-post

# 2. Install dependencies
npm install

# 3. Setup Environment
cp .env.example .env
# Open .env and insert your specific keys. You can use a local DB or your dev cloud DB.

# 4. Initialize Database Schema
npx prisma generate
npx prisma db push

# 5. Start the Development Server
npm run dev

The graphical console should now be heavily responsive on http://localhost:3000.

🗄️ Database Setup (Prisma Introspection Cycle)

⚠️ Database Safety Warning: This application shares a single PostgreSQL database instance on Supabase with other applications in this workspace. Follow the cycle below to synchronize models safely:

1. Pull all existing tables: npx prisma db pull (introspects all 20+ active tables)
2. Declare relation changes: Inject the SocialPostCreation model in your local schema.prisma and link it inside the User model.
3. Push to database: Run npx prisma db push to merge changes safely.
4. Local Schema Cleanup: Strip away other applications' models from your local schema.prisma, leaving only Account, Session, User, VerificationToken, and SocialPostCreation.
5. Compile local client: Run npx prisma generate to build your local Prisma client.
