OPFS: Next evolution in web storage or just another buzzword?
summary
OPFS is a sandboxed origin-scoped file system that supports in-place writes and a sync access handle for web workers, letting large video streams be written to disk in real time; a demo records camera video, force-crashes the tab and the .webm file remains. Benchmarks show async streams create temp files and take ~1 minute for 5,000 rows while the sync/worker path is orders of magnitude faster. Real users include Photoshop and projects using SQLite, and an OPFS Explorer reveals persisted files.
