"numeric transaction modes are deprecated in idbdatabase.transaction. use "readonly" or "readwrite"" Code Answer

the indexeddb standard is still a work in progress (although version 1 is very close to finished), and one of the recent changes was switching from the numeric constants like "idbtransaction.read_write" to just plain strings like "readwrite". it's a good idea because it makes code more concise and more readable.

the old constants will likely continue to work for some time, albeit with a warning message like you observed, but using the strings is the "correct" way to do it now and that's probably what you should use, like:

    var trans = db.transaction([key], "readwrite");
