Debug mode makes Bloom log everything it’s doing - variant lookups, inventory checks, cart sync - to the browser console on every storefront page. Use it when you (or our support team) need to see what’s happening behind the scenes on a real product page.
Debug output is visible to every visitor to your store, not just you. Turn it off as soon as you’re done troubleshooting.
Turn it on
- In Shopify admin, open Apps → Bloom.
- Go to Settings → Advanced → Debug mode.
- Turn on Enable debug mode.
- Click Save.
- Open any product page on your storefront and open the browser console (right-click → Inspect → Console).
- Look for lines prefixed with
[bloom].
What it logs
- Variant detection and inventory state
- Pre-order and Notify Me eligibility decisions
- Cart sync activity (line item properties, quantity changes)
It also attaches two helpers to the page for manual inspection:
window.bloomDebug - current widget statewindow.bloomCartDebug - current cart sync state
Turn it off
Once you’re done, turn off Enable debug mode and click Save. Off is the default, and Reset to default does the same thing.
