Zuzana Kunckova - Writing resilient code - Laracon AU 2025

Zuzana explores what it means to write resilient Laravel applications that keep working under stress, from traffic spikes and flaky networks to failing third party APIs. She walks through practical techniques including robust input validation, safer error handling, monitoring and logging, retries, graceful degradation and testing beyond the happy path so your users and future self are not blindsided when things go wrong. 📚 ## Chapters 04:41 Larabelles as a non profit, how it supports marginalised genders and a call for sponsors and allies 05:07 From human resilience vs confidence to defining resilient code and different kinds of stress on our apps 07:12 Users are creative and unpredictable, never trusting input, and introducing input validation and sanitisation 09:47 Naughty users, and the importance of only using validated data 10:03 Error handling that does not crash the application, avoids default error pages and protects sensitive information while keeping users informed 12:13 Monitoring and logging for resilient code, using tools like Sentry and Flare, and logging context developers will actually need later 13:42 Adding alerts so errors do not fail silently, being proactive instead of waiting for users to complain 14:40 Quick error recovery, retries with Laravel’s retry helper, and accounting for users with bad connectivity 15:57 Graceful degradation so one broken feature does not break everything 18:05 Expecting third party APIs to fail 19:01 Showing cached data when a remote API is down 19:35 Testing edge cases, going beyond the happy path 20:25 Simulating outages and expired caches in tests 21:41 Putting yourself in the user’s shoes, asking non developers to try the app 22:13 Resilient code checklist recap 23:07 Final thanks https://x.com/zuzana_kunckova https://bsky.app/profile/zuzana-k.com https://laracon.au
