Build drug recall and shortage alerts from FDA data

import { HealthcareDev } from "@healthcare.dev/sdk";

const hdev = new HealthcareDev();

export async function checkWatchlist(ndcs: string[], since: string) {
  const alerts = [];
  for (const ndc of ndcs) {
    const recalls = await hdev.drugs.recalls({ ndc, from: since });
    for (const r of recalls.data)
      alerts.push({
        ndc,
        kind: `Class ${r.classification ?? "?"} recall`,
        firm: r.recalling_firm,
        reason: r.reason_for_recall,
        lots: r.code_info,
      });
    const shortages = await hdev.drugs.shortages({ ndc, status: "current" });
    for (const s of shortages.data)
      alerts.push({ ndc, kind: "shortage", detail: s.availability, reason: s.shortage_reason });
  }
  return alerts.sort((a, b) => a.kind.localeCompare(b.kind)); // Class I first
}

await checkWatchlist(["0002-1433", "0006-0277"], "2026-10-01");

Are there any FDA recalls or current shortages for NDC 0002-1433? Give the class, firm and reason.
