- ID: javascript-empty-catch-block
- Severity: MEDIUM
- CWE: CWE-1069 (CWE-1069)
- Languages: JavaScript, TypeScript
- Frameworks: nodejs, express, fastify, nextjs, koa, hapi, nestjs

## Description

Detects empty catch blocks that silently swallow exceptions without
any error handling, logging, or recovery logic.

Empty catch blocks hide errors and make debugging extremely difficult.
They can mask security issues, data corruption, and system failures.

## Detection Message

Empty catch block at {location} silently swallows exceptions

## Remediation

Add proper error handling:

```javascript
try {
  await riskyOperation();
} catch (error) {
  logger.error('Operation failed:', error);
  // Handle or re-throw the error
  throw error;
}
```
