Function shouldExcludeProduct

shouldExcludeProduct(url: string, supplierName: string): Promise<boolean>

Check whether a given product (identified by URL + supplier name) is on the user's ignore list. Called from the supplier hot-path to drop results the user previously excluded. Returns false on any read error so a storage blip can't accidentally hide everything.

Parameters

url: string
Canonical product URL — same URL the supplier fetches.
supplierName: string
Supplier name, e.g. "Loudwolf".

Returns Promise<boolean>

true if an entry exists for this (url, supplier) pair.

Example

if (await shouldExcludeProduct("https://example.com/acetone", "Loudwolf")) {
  return undefined; // skip this result
}
// => true  (user previously right-click → Ignore)
// => false (not ignored, or read failed)
