Electron app with OPFS

[ankenu]

Hi. I would like to try to use OPFS in my Electron application. I have been using indexedDB before, but I noticed a performance issue with large amounts of data. I tried changing all my collections to persistence: createOPFSAdapter(“signaldb/supabase/<collection_name>.json”). I also changed in syncManager persistenceAdapter: (id) => createOPFSAdapter('signaldb/supabase/' + id + '.json')
As a result, on startup I get persistence.error TypeError: Failed to execute 'getFileHandle' on 'FileSystemDirectoryHandle': Name is not allowed. What could be the problem and is it possible to use OPFS in Electron?

I'm not sure if OPFS is available in electron. You could try to implement a custom persistence adapter that uses something like electron-store under the hood (also feel free to share your implementation afterwards 🙂)
