Why Your Web App Fails Silent Data Corruption

Episode 32 of The Web Development Podcast tackles silent data corruption in web applications — the bug that doesn't crash, doesn't log, but slowly poisons your database. Lucas and Luna walk through a real-world case: an e-commerce site where price rounding errors cost $80,000 before anyone noticed. They explain how JavaScript's `Number` type behaves in financial math, why SQLite and Postgres handle decimal data differently, and the single test pattern you can adopt today to catch it. If you've ever seen a $0.01 discrepancy or a checkout total that felt 'off', this episode will change how you think about data integrity on the front end. #SilentDataCorruption #JavaScript #FloatingPoint #DecimalMath #Postgres #SQLite #ECommerceBug #DataIntegrity #WebDevelopment #Frontend #Backend #NumberType #RoundingErrors #Testing #SoftwareBugs #FexingoBusiness #BusinessPodcast #TechPodcast Keep every episode free: buymeacoffee.com/fexingo
