Getting events on IndexedDB updates from another tab

Question

If I have IndexedDB database opened in multiple tabs, can I track data changes on all tabs without reloading?

Answer 1

There's no built in way to do this with IndexedDB alone. You basically have two options:

1. Poll IndexedDB with some frequency and check for new values

2. Use some other way of cross-tab communication to send a signal that you need to check for new values from IndexedDB. For example localStorage (emits cross-tab events when something changes) or a BroadcastChannel (designed exactly for the purpose of cross-tab communication, but does not have perfect cross browser support).
