Installation

1. Clone the repository

   git clone https://github.com/simplyrk/inspiro.git
   cd inspiro

2. Install dependencies

   npm install

3. Set up environment variables

   Copy the example environment file and update with your values:

   cp .env.example .env

   Update the .env file with your database credentials and NextAuth configuration:

   # Database
   DATABASE_URL="postgresql://user:password@host/database?sslmode=require"
   
   # NextAuth
   NEXTAUTH_URL="http://localhost:3000"
   NEXTAUTH_SECRET="your-secret-key-here"

   Generate a secure secret for NextAuth:

   openssl rand -base64 32

4. Set up the database

   Run Prisma migrations to create the database schema:

   npm run prisma:push

   Generate Prisma client:

   npm run prisma:generate

   (Optional) Seed the database with sample quotes:

   npm run seed

5. Start the development server

   npm run dev

   Open http://localhost:3000 in your browser.

Available Scripts

• npm run dev - Start development server with Turbopack
• npm run build - Build for production
• npm run start - Start production server
• npm run lint - Run ESLint
• npm run prisma:generate - Generate Prisma client
• npm run prisma:push - Push schema changes to database
