• void persist()

Detailed Description

In a WebAssembly build, files live in memory and are gone when the page reloads. Clayground.Storage therefore keeps the data directory (where QML LocalStorage puts its databases) in the browser's IndexedDB: it is loaded from there before the app starts, and persist() writes it back.

KeyValueStore calls persist() after every change, so a KeyValueStore needs nothing more. Call it yourself only after writing to that directory some other way, e.g. with QtQuick.LocalStorage directly:

import QtQuick.LocalStorage
import Clayground.Storage

function save(db, score) {
    db.transaction(tx => tx.executeSql('INSERT INTO scores VALUES (?)', [score]))
    StorageSync.persist()
}

In a native build there is nothing to write back and persist() does nothing.
