Storing data in indexedDB instead of sessionStorage is necessary due to the size exceeding 5 MB.
I'm uncertain about the cleanup strategy. I want the data to persist during page reloads or navigation, but I'd like it removed if the user closes the browser tab to save space.
What is the best way to achieve this? It needs to be functional at least in Chrome.
To prevent unnecessary database clutter, one approach is to store an indicator in the session storage. If this indicator is not present, you can then proceed to delete the designated database.
(async() =>
{
if (!sessionStorage.getItem('just-a-placeholder'))
{
indexedDB.deleteDatabase('temp');
sessionStorage.setItem('just-a-placeholder', true);
}
const databases = await indexedDB.databases();
console.log(databases.find(db => db.name === 'temp') !== undefined)
await indexedDB.open('temp');
})();
