Sync results

Pull a whole season into your database without duplicating rows on a re-run.

  1. 1

    Walk every page

    The listing answers with `total`, so you know when to stop without guessing.

    javascript
    async function fetchAllPages(path) {
  const out = [];
  let page = 1;
  for (;;) {
    const url = new URL(`https://www.kaax-agritech.com${path}`);
    url.searchParams.set("page", String(page));
    url.searchParams.set("limit", "100");

    const res = await fetch(url, {
      headers: { apiKey: process.env.KAAX_API_KEY },
    });
    if (!res.ok) throw new Error(`Kaax API ${res.status}: ${await res.text()}`);

    const { total, data } = await res.json();
    out.push(...data);
    if (out.length >= total || data.length === 0) return out;
    page += 1;
  }
}
  2. 2

    Upsert by the Kaax id

    That way re-running the sync duplicates nothing, which is what makes it safe to put on a cron.

    javascript
    for (const a of await fetchAllPages("/api/v2/analyses?type=counting")) {
  await db.analyses.updateOne(
    { kaaxId: a._id },
    { $set: { ...a.analysis, name: a.name, syncedAt: new Date() } },
    { upsert: true },
  );
}
