💡 Tips Rekayasa Perangkat Lunak (SiHubung Engineering Best Practice)
Selalu gunakan pendekatan deklaratif, validasi input seawal mungkin di boundary layer, dan lakukan logging terstruktur untuk memudahkan observability ketika sistem dijalankan di lingkungan cloud produksi.
Kesimpulan
Dengan mengikuti langkah-langkah terstruktur di atas, implementasi modul Anda akan jauh lebih rapi, aman dari bug umum, serta siap diskalakan ke lingkungan produksi.
