I implement some logging library for Chrome that when my webapp codes call console.log(message), I also write the message data into IndexedDB store, something like

    const db = indexedDB.open("store", 1);
    const transaction = db.transaction(['devlogs'], "readwrite");
    const objectStore = transaction.objectStore('devlogs');

    const log = {
        timestamp: new Date(),
        message,
        level
    };

    await objectStore.add(log);
    await transaction.done;

I also want my logging library to delete the old log, say 10 days ago, automatically.

I only have limited experience with IndexedDB, so to me, the simple way to do that is in the db’s onsuccess handler I use a transaction to delete the old log.

But if there is another transaction to add the log, will the delete action cause the problem ? Is there a better place to delete the old log ?
