I’m seeing a few comments from people suggesting that localStorage on an iPad is unreliable. Can anyone confirm that they are happily using localStorage on an iPad? I understand that there is a 5Mb limit too – is that still the case?
Thanks
I’ve been working on a project that uses localStorage on an iPad. In my experience, the localStorage is perfectly stable. However, there are two things to consider:
Yes, the storage-limit is still 5Mb. Since characters are stored UTF16, only 2.5M characters can be stored in localStorage.
In contrast to other localStorage implementations, localStorage.setItem() doesn’t delete any previous items with the same key before storing the new item. In other words: When overwriting an item, one should always call localStorage.removeItem() before calling localStorage.setItem(), or you’ll quickly run out of space.
