Ringkasan

Test edit dari production API

Data Model

struct RemoteProduk {
    id: String,
    nama: String,
    harga: i64,
    updated_at: Option<String>,
}

struct RemoteProduk {

id: String,

nama: String,

harga: i64,

updated_at: Option<String>,

}

Alur
  • First sync: since=null → full pull
  • Sync berikutnya: since=last_sync_ts → hanya yang berubah
  • Server query: WHERE updated_at > since
  • Client: upsert ke DB lokal, update sync_produk_at
  • Retry 2× kalau fetch gagal
API
GET /api/produk?semua=1&since=2026-10-08T12:00:00Z

Response: [{ id, nama, harga, updated_at }]
GET /api/produk?semua=1&since=2026-10-08T12:00:00Z
Response: [{ id, nama, harga, updated_at }]

Backwards compatible: tanpa `since` = full pull.
Backwards compatible: tanpa since = full pull.
Pitfall
⚠ Ganti tenant → reset sync_produk_at, wajib full pull
⚠ updated_at harus ada DB trigger auto-update
⚠ Jika server belum deploy ?since=, client fallback full pull
