A reset with no backup wiped my whole portfolio to zero

Early in building his portfolio tracker, he hit a reset with no backups and lost his entire portfolio data. It was unrecoverable. Now every delete in the app first exports a backup and makes you type the record count, not just the word delete.

This one went wrong. Read what happened so you don’t hit the same problem.

How it works

Hit a reset in the app while building it
Find the whole portfolio gone, with no backup to bring back
Rebuild the data
Change the app so every delete exports a backup first and requires typing the record count

Why it’s worth knowing

The tool he built to keep his investing honest could not keep his investing data. One click and the record of it was gone.
