Traditional web storage solutions like IndexedDB and LocalStorage are constrained by performance bottlenecks, memory limitations, and inefficiencies that can make advanced use cases—like video recording or large file manipulation—frustrating or impossible. Enter the Origin Private File System (OPFS), a game-changing web API designed to bring native-like storage performance to the browser. In this talk, we’ll demystify OPFS, explore its key features such as in-place writes and sandboxed security, and demonstrate its real-world impact through engaging demos. Learn how industry leaders like Photoshop and SQLite use OPFS to push the boundaries of what’s possible on the web. By the end of this session, you’ll be equipped with practical knowledge to start using OPFS in your own projects and a clear understanding of when and why to choose it over other storage solutions.
