Host-page demo

BPE L Extractor

Test the browser extension the same way a dealer portal would: drop a marker element on the page, keep attributes in sync, and listen for the result event.

Load this site over http://localhost with the extension installed. The content script does not run on file://. Use npx serve -p 1234 from this folder.

What the extension does

1. Discover

Scans the page (and iframes) for data-ext-fetch markers and injects an icon into each one.

2. Fetch

Opens LTA VRL, scrapes dereg rebate and/or transfer fee, then returns merged records plus optional screenshots.

3. Return

Dispatches form-result--{formId} on the host page and shows the same payload in the side panel.
