Fix TimeoutError in Gatsby

Handling Timeout Errors in Gatsby

Timeouts occur when an operation takes longer than the allowed duration. In Gatsby applications, unhandled timeouts cascade into poor user experiences and can even bring down entire services.

Why Timeouts Happen

• Slow or unresponsive external APIs
• Database queries running against large datasets without indexes
• Network latency spikes or DNS resolution delays
• Resource contention under high load

Implementing Proper Timeouts

// Bad: no timeout handling
useEffect(() => {
  fetch("/api/data").then(r => r.json()).then(setData);
}, []);

// Good: timeout + cleanup
useEffect(() => {
  const controller = new AbortController();
  const timer = setTimeout(() => controller.abort(), 8000);
  fetch("/api/data", { signal: controller.signal })
    .then(r => r.json())
    .then(setData)
    .catch(() => setError("Request timed out"));
  return () => { clearTimeout(timer); controller.abort(); };
}, []);

Timeout Strategy Tips

1. Set explicit timeouts on every external call — never rely on defaults
2. Use circuit breakers for repeatedly failing services
3. Return graceful fallbacks instead of hanging indefinitely
4. Log timeout events with enough context to identify patterns
