How the Web Locks API Prevents Double-Spend in Browser Apps

In episode 160 of The Web Development Podcast, Lucas and Luna explore the Web Locks API, a browser feature that lets web apps coordinate access to shared resources. They explain how it works, why it matters for everything from offline-first apps to real-time collaboration, and walk through a practical example: preventing double-spend in a client-side budget tracker. They also touch on the API's surprising history, its pitfalls, and how it fits into the broader evolution of the web platform. If you've ever written a race condition in JavaScript or wondered how to safely manage state across tabs, this episode gives you a concrete tool to add to your belt. #WebLocksAPI #BrowserAPIs #WebDevelopment #JavaScript #Concurrency #RaceConditions #OfflineFirst #WebWorkers #SharedWorker #IndexedDB #RealTimeCollaboration #TechPodcast #FexingoBusiness #BusinessPodcast #WebPlatform #BrowserFeatures #SoftwareEngineering #FrontendDevelopment Keep every episode free: buymeacoffee.com/fexingo
