A hobby full-stack project I built to learn modern app development end to end.

It scrapes the announcement boards of the Faculty of Electrical Engineering,
University of Banja Luka, stores the announcements in PostgreSQL, and lets
students browse and subscribe to subjects from a mobile app. Subscribers get
push notifications when new announcements are posted.

## Tech Stack

- **Backend:** Spring Boot 3.5 (Java 21), REST API, PostgreSQL
- **Frontend:** React Native / Expo (Expo Router, NativeWind)
- **Notifications:** Firebase Cloud Messaging
- **Tooling:** Docker, Gitea Actions for CI/CD, deployed to a self-hosted home server

## Project Structure

- `backend/` — Spring Boot REST API and the scraper
- `frontend/` — Expo mobile app

## Backend

```bash
cd backend
cp src/main/resources/application.properties.example src/main/resources/application.properties  # fill in datasource + jwt.secret
docker compose up -d   # local Postgres
./gradlew bootRun
```

Run tests: `./gradlew test`

## Frontend

```bash
cd frontend
npm install
# set EXPO_PUBLIC_API_URL in .env to the backend base URL
npm start
```

## Status

Semi-actively developed as a learning project. It is an app I actually use, and
maybe others will find it useful too.
