Challenges in storing large amounts of client-side data

There are several web APIs that allow you to store data locally on the user’s device, some that even allow working with large datasets. But for large local datasets, there are currently some challenges related to the functionality of current APIs and how easy it can be for the user’s data to inadvertently be deleted, whether by accident or by some automated background cleanup by the browser to save space. In this talk I will discuss the current state of PWAs using large amounts of local data, as well as look to the future for how the situation could be improved.
