API Development & Integration

Tolong design dan implement API user management RESTful lengkap project sekarang.

Fungsi yang dibutuhkan:
- User register (email + password, password encrypted storage)
- User login (JWT token auth)
- Dapatkan info user (butuh auth)
- Edit profil user (butuh auth)
- Daftar user (pagination, search, admin permission)

Kebutuhan teknis:
1. RESTful style, HTTP method + status code bener
2. Parameter validate (pakai Joi/Zod/Pydantic sesuai bahasa project)
3. Response format konsisten: { code, data, message }
4. Error handling + logging lengkap
5. Generate dokumentasi Swagger/OpenAPI
6. Generate test collection Postman/Insomnia

Generate sesuai tech stack project sekarang, keep code style consistent.

Ini dokumentasi API third-party:

[Copas JSON Swagger/OpenAPI atau URL]

Tolong generate TypeScript SDK client:
1. Generate method setiap endpoint (lengkap type definition)
2. HTTP client konsisten (base axios/fetch)
3. Request interceptor: auto-include Authorization header
4. Response interceptor: error handling unified + retry logic
5. Support request timeout sama cancel
6. Export semua TypeScript type definition
7. Tulis README + use example

SDK support Tree-shaking, import selective nggak bundle yang nggak pakai.

Tambahkan middleware berikut ke API service project sekarang:

1. Middleware Rate Limiting (Rate Limiting):
   - Default tiap IP 60 request per menit
   - Endpoint login tiap IP 5 request per menit
   - Kasih X-RateLimit-* response header
   - Exceed limit return 429 + pesan friendly

2. Middleware Authentication:
   - JWT Token verify
   - Token expire otomatis refresh (Refresh Token mechanism)
   - Check role permission (admin / user / guest)

3. Middleware Logging:
   - Log setiap request: method, path, durasi, status code
   - Error request otomatis log request body + stack trace
   - Format log cocok ELK atau CloudWatch

Pastikan order execution middleware bener, kasih juga code register ke route.
