Quick Start

Installation

The code intelligence package is included in FARM projects by default. To enable it, add configuration to your farm.config.ts:

export default defineConfig({
  codeIntelligence: {
    enabled: true,
    indexing: {
      include: ["src/**/*", "packages/**/*"],
      exclude: ["**/test/**", "**/*.test.*"],
      watch: true,
    },
    ai: {
      provider: "local",
      model: "codellama",
    },
  },
});

First Run

Code Intelligence initializes automatically when you start your FARM project:

farm dev
# ✓ Creating vector database
# ✓ Indexing codebase (found 127 files)
# ✓ Building semantic graph
# ✓ Code Intelligence ready!

Usage

CLI Commands

Search Your Codebase

export function CodeSearch() {
  const [query, setQuery] = useState('');
  const [results, setResults] = useState([]);
  const client = new CodeIntelligenceClient();

  const handleSearch = async () => {
    const response = await client.query({
      query,
      maxResults: 20,
      includeContext: true
    });
    setResults(response.results);
  };

  return (
    <div>
      <input
        value={query}
        onChange={(e) => setQuery(e.target.value)}
        placeholder="Search your codebase..."
      />
      <button onClick={handleSearch}>Search</button>

      {results.map(result => (
        <SearchResult key={result.id} result={result} />
      ))}
    </div>
  );
}

Real-time Updates

// Real-time indexing status
import { WebSocketClient } from '@farm-framework/code-intelligence/client';

export function IndexingStatus() {
  const [progress, setProgress] = useState({ completed: 0, total: 0 });
  const wsClient = new WebSocketClient({
    url: 'ws://localhost:8001/api/code-intelligence/stream'
  });

  useEffect(() => {
    wsClient.connect();

    wsClient.onIndexProgress(setProgress);

    return () => wsClient.disconnect();
  }, []);

  const percentage = Math.round((progress.completed / progress.total) * 100);

  return (
    <div>
      <div>Indexing Progress: {percentage}%</div>
      <progress value={progress.completed} max={progress.total} />
      <div>{progress.completed} / {progress.total} files</div>
    </div>
  );

Components

• CLI Interface - TypeScript commands integrated with FARM CLI
• API Layer - FastAPI endpoints for query execution
• Query Engine - Natural language query planning and execution
• Vector Store - ChromaDB for semantic search and entity storage
• File Watcher - Real-time incremental indexing
• Python Backend - AST parsing, embeddings, and AI integration

Data Flow

1. Indexing - File watcher detects changes → Python parser extracts entities → Embeddings generated → Vector store updated
2. Querying - Natural language query → Query planner → Vector search → AI synthesis → Formatted response
3. Real-time - WebSocket streams for live updates and streaming results

Performance

Benchmarks

• Initial Indexing - ~1000 files/minute on average hardware
• Incremental Updates - <100ms per file change
• Query Response - <500ms for semantic search
• Memory Usage - ~500MB for medium projects (10K+ files)

Optimization Tips

// Optimize for large codebases
export default defineConfig({
  codeIntelligence: {
    performance: {
      parallelism: 8, // Use more CPU cores
      embedBatchSize: 64, // Larger batches for embeddings
      cacheSize: "2GB", // More cache for better performance
    },
    indexing: {
      batchSize: 200, // Process more files at once
      maxFileSize: 2097152, // 2MB file limit
    },
  },
});

Troubleshooting

Common Issues

Index Not Building

# Check if watcher is disabled
echo $FARM_INTEL_DISABLE_WATCH

# Check index status
farm intel index --status

# Force rebuild
farm intel index --rebuild

Slow Performance

# Check memory usage
farm intel index --stats

# Clear cache
rm -rf .farm/intel

# Optimize configuration

Python Dependencies

# Install required Python packages
pip install chromadb sentence-transformers torch networkx numpy

# Check Python environment
python --version

Debug Mode

# Enable verbose logging
FARM_INTEL_DEBUG=1 farm dev

# Check API logs
curl http://localhost:8001/api/code-intelligence/status
