Bekgram (Flutter + MySQL + Realtime Socket)

1. MySQL bazani yaratish

server/sql/init.sql ichida bekgram_local database va bekgram_app user tayyor.

cd server
./scripts/setup_mysql.sh

Agar root password so'rasa, kiriting.

2. Backend serverni ishga tushirish

cd server
cp .env.example .env
npm install
npm run start

Server: http://localhost:3000 Health: http://localhost:3000/api/health

3. Flutter appni ishga tushirish

flutter pub get
flutter run -d chrome

Android emulator (Chrome sekin bo'lsa tavsiya):

flutter emulators
flutter emulators --launch <emulator_id>
flutter run -d <device_id>

Eslatma:

• Android emulator uchun API_HOST default ravishda 10.0.2.2 bo'lib ishlaydi.
• Telefon (real device) ulasangiz, hostni qo'lda bering:

flutter run -d <device_id> --dart-define=API_HOST=192.168.1.34 --dart-define=API_PORT=3000

Yoki web build:

flutter build web --no-wasm-dry-run
python3 -m http.server 8080 --directory build/web

4. Telefon (iPhone) uchun

Agar iPhone orqali ko'rsangiz, backend host ham telefon uchun ochiq bo'lishi kerak.

Misol build:

flutter build web --dart-define=API_HOST=192.168.1.34 --dart-define=API_PORT=3000

Keyin frontend: http://192.168.1.34:8080 Backend: http://192.168.1.34:3000

API stack

• Auth: JWT
• DB: MySQL/MariaDB
• Realtime: Socket.IO (message:new, chat:updated, presence:update)
