Writing resilient code

" summary

Covers techniques for making Laravel applications resilient to traffic spikes, flaky networks and failing third-party APIs by using robust input validation and sanitisation, safer error handling that avoids leaking sensitive info, and monitoring with tools like Sentry or Flare plus alerting. Walks through concrete practices such as using Laravel’s retry helper for quick recovery, graceful degradation and cached fallbacks when remote APIs fail, and testing edge cases and simulated outages (including expired caches) to catch non-happy-path failures.
