# Configuration

> Configure KafkaCode for your project

## Gitignore Support

KafkaCode automatically respects your `.gitignore` file. Add patterns to exclude files from scanning:

```gitignore theme={null}
# .gitignore
*.env
*.key
*.pem
secrets/
config/local.*
test-fixtures/
```

## Custom Ignore Patterns

Extend the built-in ignore patterns programmatically:

```javascript theme={null}
const FileScanner = require('kafkacode/dist/FileScanner');

const scanner = new FileScanner('./src');

// Add custom ignore directories
scanner.ignoreDirs.add('generated');
scanner.ignoreDirs.add('third-party');
scanner.ignoreDirs.add('mock-data');

// Add custom file extensions
scanner.supportedExtensions.add('.jsx');
scanner.supportedExtensions.add('.tsx');

const files = scanner.scanFiles();
```

## Environment-Specific Configuration

```javascript theme={null}
// config/kafkacode-config.js
module.exports = {
  development: {
    ignoreDirs: ['test-fixtures', 'mock-data'],
    verbose: true
  },
  production: {
    ignoreDirs: ['tests', 'docs'],
    verbose: false,
    exitOnIssues: true
  }
};

// Usage
const config = require('./config/kafkacode-config')[process.env.NODE_ENV];

const scanner = new FileScanner('./src');
config.ignoreDirs.forEach(dir => scanner.ignoreDirs.add(dir));

const engine = new AnalysisEngine(config.verbose);
```
