# Media Aggregation and Sorting System
This is my final-year mobile app project.

It is an Expo/React Native app that pulls media from multiple sources (device storage, Google Photos picker flow, and NAS) and shows everything in one timeline-style view.

## What This Project Does

- Local user accounts (register/login)
- Local SQLite database on-device (`PhotosApp.db`)
- Service onboarding for:
  - Google Photos
  - NAS
  - iCloud placeholder
- Unified media view with source badges
- Collections/albums screen
- Search screen
- Settings screen for theme, services, and backup options

## Current Architecture

### App entry and navigation

- Entrypoint is `App.js`
- `App.js` initializes the database, then mounts navigation
- Stack flow:
  - `Login`
  - `Register`
  - `Onboarding`
  - `MainTabs`
  - `Settings`
- Bottom tabs in `MainTabs`:
  - `Library` (`HomeScreen`)
  - `Search` (`SearchScreen`)
  - `Collections` (`AlbumsScreen`)

### Data layer

Database setup lives in `src/services/DatabaseService.js`.

Tables currently used:
- `users`
- `linked_accounts`
- `media`

Passwords are hashed with SHA-256 via `src/services/CredentialEncryption.js`.
Linked account payloads are stored as Base64-encoded JSON strings.

### Service/auth layer

Auth services are in `src/AUTH/`:
- `GoogleAUTH.js`
- `NASAUTH.js`
- `IOSAUTH.js` (placeholder)

Common interface base: `src/AUTH/AuthServiceBase.js`.

API client wrappers are in `src/API/`.

### Backend (NAS side)

There is a separate Node/Express backend in `ServerFiles/server.js`.

It handles NAS connection and file operations for the mobile app.
