Quick Start

Option 1: Use the Live Application

Visit the deployed application: https://ai-code-reviewer-5fq.pages.dev

Option 2: Local Development

# Clone the repository
git clone <your-repo-url>
cd ai_code_reviewer

# Install backend dependencies
npm install

# Install frontend dependencies
cd frontend
npm install
cd ..

# Start the backend Worker (in one terminal)
npm run dev

# Start the frontend (in another terminal)
npm run dev:frontend

The frontend will be available at http://localhost:5173 and connects to the local Worker at http://localhost:8787.

Option 3: HTTP API

Use the REST API directly without the frontend:

# Submit code for review
curl -X POST https://ai-code-reviewer-backend.mohammedfirdousaraoye.workers.dev/api/review \
  -H "Content-Type: application/json" \
  -d '{
    "code": "console.log(\"Hello World\");",
    "category": "quick",
    "language": "javascript"
  }'

# Get all reviews
curl https://ai-code-reviewer-backend.mohammedfirdousaraoye.workers.dev/api/reviews

# Check service status
curl https://ai-code-reviewer-backend.mohammedfirdousaraoye.workers.dev/api/status

Language Detection

The application intelligently detects programming languages using pattern recognition:

• Automatic Detection - Analyzes code syntax to identify the language
• Validation - Prevents mismatched language selections
• Smart Suggestions - Recommends correct language when mismatch detected
• Non-code Detection - Identifies and rejects plain text submissions

Supported Languages

JavaScript, TypeScript, Python, Java, Go, Rust, C++, C#, PHP, Ruby, Swift, Kotlin, and more.

Keyboard Shortcuts

• Ctrl/Cmd + K - Focus code input
• Ctrl/Cmd + Enter - Submit review
