## 🎯 Ringkasan Proyek
|
||||
|
||||
Proyek ini adalah pengembangan dari **Starter Project yang sudah disediakan**, bukan membuat dari awal. Kami mengambil codebase yang ada dan mengembangkannya dengan fitur-fitur baru, perbaikan bug, dan peningkatan UI/UX.
|
||||
|
||||
### Prinsip Pengembangan
|
||||
✅ **Mengembangkan code yang sudah ada** - Tidak membuat dari awal
|
||||
✅ **Improve, bukan Replace** - Perbaiki yang salah, kembangkan yang ada
|
||||
✅ **DRY Principle** - Hindari duplikasi code yang tidak perlu
|
||||
✅ **Reuse Code** - Manfaatkan code yang sudah berfungsi

|
||||
```
|
||||
|
||||
**Workflow:**
|
||||
1. App mengirim data absensi ke N8n
|
||||
2. N8n melakukan validation server-side
|
||||
3. Coordinate obfuscation (privacy)
|
||||
4. Image Base64 encoding
|
||||
5. Timestamp validation
|
||||
6. Record disimpan di server

## 📊 Database Schema Evolution
|
||||
|
||||
### Version 1.0 (Starter)
|
||||
```sql
|
||||
CREATE TABLE users (
|
||||
npm TEXT PRIMARY KEY,
|
||||
nama TEXT,
|
||||
password TEXT,
|
||||
createdAt TEXT
|
||||
);
|
||||
|
||||
CREATE TABLE absensi (
|
||||
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
||||
npm TEXT,
|
||||
timestamp TEXT,
|
||||
latitude REAL,
|
||||
longitude REAL,
|
||||
foto BLOB,
|
||||
status TEXT,
|
||||
FOREIGN KEY (npm) REFERENCES users(npm)
|
||||
);
|
||||
```
|
||||
|
||||
### Version 2.0 (Current)
|
||||
```sql
|
||||
CREATE TABLE users (
|
||||
npm TEXT PRIMARY KEY,
|
||||
nama TEXT,
|
||||
password TEXT,
|
||||
createdAt TEXT
|
||||
);
|
||||
|
||||
CREATE TABLE absensi (
|
||||
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
||||
npm TEXT,
|
||||
timestamp TEXT,
|
||||
latitude REAL,
|
||||
longitude REAL,
|
||||
foto BLOB,
|
||||
mata_kuliah TEXT, -- ✨ NEW FIELD
|
||||
status TEXT,
|
||||
FOREIGN KEY (npm) REFERENCES users(npm)
|
||||
);
|
||||
```
|
||||
|
||||
**Migration:** `fallbackToDestructiveMigration()` (untuk development)

## 🎯 Key Takeaways
|
||||
|
||||
### ✅ Yang Dilakukan dengan BENAR
|
||||
1. ✅ Menggunakan starter project yang ada
|
||||
2. ✅ Mengembangkan bukan membuat ulang
|
||||
3. ✅ Reuse code yang sudah berfungsi
|
||||
4. ✅ Fix bugs tanpa mengubah core logic
|
||||
5. ✅ Dokumentasi lengkap untuk handover
|
||||
6. ✅ Gunakan AI untuk productivity
|
||||
|
||||
### ⚠️ Yang Perlu Diperhatikan
|
||||
1. ⚠️ Radius validation masih unlimited (untuk testing)
|
||||
2. ⚠️ Database migration untuk production
|
||||
3. ⚠️ Webhook endpoint production
|
||||
4. ⚠️ Security review before deployment
|
||||
5. ⚠️ User acceptance testing needed
|
||||
|
||||
### 🚀 Next Steps
|
||||
1. Testing di production environment
|
||||
2. User feedback collection
|
||||
3. Performance optimization if needed
|
||||
4. Scale infrastructure untuk load
|
||||
5. Continuous monitoring & maintenance

## 📞 Catatan Penting
|
||||
|
||||
### Prinsip Pengembangan (DRY - Don't Repeat Yourself)
|
||||
```
|
||||
❌ JANGAN: Buat ulang code dari awal
|
||||
✅ LAKUKAN: Kembangkan yang sudah ada
|
||||
✅ LAKUKAN: Fix bug tanpa mengubah logic
|
||||
✅ LAKUKAN: Reuse module & function
|
||||
✅ LAKUKAN: Dokumentasi perubahan dengan jelas
|
||||
```
|
||||
|
||||
### Untuk Koordinat Privasi
|
||||
```
|
||||
📍 Data awal tetap dari GPS
|
||||
📍 Bisa ditambah/kurangi di aplikasi untuk privacy
|
||||
📍 Obfuscation final dilakukan di N8n server-side
|
||||
📍 Real coordinate disimpan di backend dengan encryption
|
||||
```
