Say what? WebSQL was an experiment that ended up being replaced by indexeddb- it has been deprecated ever since, and was never part of the web standards.
Itβs telling that despite IndexedDB being around forever people would still rather download an entire SQLite runtime than use it. A deeply unsatisfying API.
If I remember correctly, the main argument against web sql was that it really was just SQLite disguised as a web standard. I.e. there was a single implementation which defined the spec: SQLite. Every browser implementation relied on it.
In retrospect, with the chrome monoculture we have today, this seems like a silly argument but at the time it was a legitimate concern.
