🛠️ Setup & Installation

Prerequisites

• Node.js 18+ and npm
• PostgreSQL database
• GitHub OAuth App
• OpenRouter API key (for DeepSeek model access)

1. Clone the repository

git clone https://github.com/yourusername/github-pr-reviewer.git
cd github-pr-reviewer

2. Install dependencies

npm install

3. Set up environment variables

Create a .env.local file in the root directory:

# Database

# NextAuth.js
NEXTAUTH_URL="http://localhost:3000"
NEXTAUTH_SECRET="your-secret-key"

# GitHub OAuth
GITHUB_CLIENT_ID="your-github-client-id"

# OpenRouter API
OPENROUTER_API_KEY="your-openrouter-api-key"

4. Set up the database

# Generate Prisma client
npx prisma generate

# Push the database schema
npx prisma db push
