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:
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
