## Overview

Network debugging identifies connectivity issues, latency problems, and data transmission errors that impact application performance.

## When to Use

- Slow loading times
- Failed requests
- Intermittent connectivity
- CORS errors
- SSL/TLS issues
- API communication problems

## Quick Start

Minimal working example:

```yaml
Chrome DevTools Network Tab:

Columns:
  - Name: Request file/endpoint
  - Status: HTTP status code
  - Type: Resource type (xhr, fetch, etc)
  - Initiator: What triggered request
  - Size: Resource size / transferred size
  - Time: Total time to complete
  - Waterfall: Timeline visualization

Timeline Breakdown:
  - Queueing: Waiting in queue
  - DNS: Domain name resolution
  - Initial connection: TCP handshake
  - SSL: SSL/TLS negotiation
  - Request sent: Time to send request
  - Waiting (TTFB): Time to first byte
  - Content Download: Receiving response

Network Conditions:

Throttling Presets:
  - Fast 3G: 1.6 Mbps down, 750 Kbps up
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Follow established patterns and conventions
- Write clean, maintainable code
- Add appropriate documentation
- Test thoroughly before deploying

### ❌ DON'T

- Skip testing or validation
- Ignore error handling
- Hard-code configuration values
