### Project Idea
This is a travel app based on wikipedia informations.
The user can choose a city, we show the city on the map with some info about it (from wikipedia, like city summary) and show things to do there.
We need to store in mysql data from wikipedia, opentripmap and overpass for cache.
---
## Technical Architecture
### Tech Stack
**Frontend:**
- Alpine.js for interactive UI components
- Tailwind CSS for styling (or Bootstrap 5)
- Leaflet.js for interactive maps
- Laravel Livewire (optional) for dynamic components
- Blade templating engine
**Backend:**
- Laravel 10/11 (PHP)
- MySQL database for caching API responses
- Redis for caching and queue management
- Laravel HTTP Client (Guzzle) for API requests
- Laravel Cache for API response caching
- Laravel Jobs/Queues for background API fetching
**External APIs:**
- Wikipedia API - City summaries and information
- OpenTripMap API - Points of interest and attractions
- Overpass API (OpenStreetMap) - Geographic data and additional POIs
---
## Database Schema
### Migrations
**cities** (create_cities_table.php)
```php
$table->id();
$table->string('name');
$table->string('country');
$table->decimal('latitude', 10, 7);
$table->decimal('longitude', 10, 7);
$table->text('wikipedia_summary')->nullable();
$table->string('wikipedia_url')->nullable();
$table->string('wikipedia_page_id')->nullable();
$table->timestamps();
$table->timestamp('wikipedia_cached_at')->nullable();
// Indexes
$table->index(['name', 'country']);
$table->index('wikipedia_cached_at');
```
**attractions** (create_attractions_table.php)
```php
$table->id();
$table->foreignId('city_id')->constrained()->onDelete('cascade');
$table->string('name');
$table->text('description')->nullable();
$table->decimal('latitude', 10, 7);
$table->decimal('longitude', 10, 7);
$table->string('category')->nullable();
$table->enum('source', ['opentripmap', 'overpass', 'wikipedia']);
$table->string('source_id')->nullable();
$table->decimal('rating', 3, 2)->nullable();
$table->string('image_url')->nullable();
$table->timestamps();
$table->timestamp('cached_at')->nullable();
// Indexes
$table->index('city_id');
$table->index('category');
$table->index('cached_at');
```
**users** (Laravel's default users table with modifications)
```php
$table->id();
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
```
**favorites** (create_favorites_table.php)
```php
$table->id();
$table->foreignId('user_id')->constrained()->onDelete('cascade');
$table->foreignId('city_id')->constrained()->onDelete('cascade');
$table->timestamps();
// Indexes
$table->unique(['user_id', 'city_id']); // Prevent duplicate favorites
$table->index('user_id');
```
**trips** (create_trips_table.php)
```php
$table->id();
$table->foreignId('user_id')->constrained()->onDelete('cascade');
$table->string('name');
$table->text('description')->nullable();
$table->timestamps();
// Indexes
$table->index('user_id');
```
**city_trip** (create_city_trip_table.php) - Pivot table
```php
$table->id();
$table->foreignId('trip_id')->constrained()->onDelete('cascade');
$table->foreignId('city_id')->constrained()->onDelete('cascade');
$table->integer('order')->default(0); // Order of cities in trip
$table->timestamps();
// Indexes
$table->index(['trip_id', 'city_id']);
```
**personal_access_tokens** (Laravel Sanctum - auto-generated)
- Handles API tokens for mobile app authentication
**Note:** Laravel's built-in caching system (Redis/Database) will handle cache metadata, so a separate cache_metadata table is optional.

## Implementation Steps
### Phase 1: Laravel Project Setup
1. Initialize Laravel project: `composer create-project laravel/laravel wiki_travel_site`
2. Install Laravel Sanctum for API authentication: `composer require laravel/sanctum`
3. Publish Sanctum config: `php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"`
4. Install Tailwind CSS: `npm install -D tailwindcss postcss autoprefixer && npx tailwindcss init`
5. Configure MySQL database connection in `.env`
6. Set up Redis for caching
7. Create database migrations for cities, attractions, users, favorites, trips
8. Run migrations: `php artisan migrate`
9. Configure CORS for mobile app in `config/cors.php`
### Phase 2: Models & Services
1. Create Eloquent models: `City`, `Attraction`, `Trip`, `Favorite`
2. Define model relationships:
- City hasMany Attractions
- User hasMany Favorites
- User hasMany Trips
- Trip belongsToMany Cities (pivot: city_trip)
- City belongsToMany Trips
3. Add HasApiTokens trait to User model for Sanctum
4. Create service classes:
- `WikipediaService` - Fetch city data from Wikipedia API
- `OpenTripMapService` - Fetch attractions from
- OpenTripMap API
- `OverpassService` - Fetch geographic data from Overpass API
5. Implement Laravel Cache facade for API response caching
6. Create Jobs for background API fetching:
- `FetchCityDataJob`
- `FetchAttractionsJob`
### Phase 3: Authentication & Controllers
1. Create `AuthController` for registration/login/logout
2. Create `CityController` for web routes
3. Create API controllers:
- `API\CityController` - City and attraction endpoints
- `API\FavoriteController` - Favorite management
- `API\TripController` - Trip/itinerary management
- `API\UserController` - User profile management
4. Define web routes in `routes/web.php`
5. Define API routes in `routes/api.php` with Sanctum middleware
6. Implement API resource classes for JSON responses:
- `CityResource`
- `AttractionResource`
- `TripResource`
- `UserResource`
7. Create Form Request validators for registration and trip creation
### Phase 4: Frontend Views
1. Create Blade layouts:
- `layouts/app.blade.php` - Main layout with Tailwind/Bootstrap
- `welcome.blade.php` - Homepage with search
- `cities/show.blade.php` - City details page
2. Install and configure Alpine.js
3. Integrate Leaflet.js for maps
4. Create Alpine.js components:
- City search with autocomplete
- Interactive map with markers
- Attractions filter and list
5. Style with Tailwind CSS utility classes
### Phase 5: Integration & Caching
1. Implement cache logic in services (30 days for Wikipedia, 7 days for attractions)
2. Configure Redis cache driver in `config/cache.php`
3. Add error handling and logging
4. Create artisan commands:
- `php artisan cache:clear-cities` - Clear city cache
- `php artisan attractions:refresh {cityId}` - Refresh attraction data
5. Test all API integrations
### Phase 6: Polish & Optimization
1. Add loading states with Alpine.js
2. Implement responsive design (mobile-first with Tailwind)
3. Optimize database queries (eager loading, indexing)
4. Add pagination for attractions list
5. Implement search history using Laravel sessions
6. Write feature tests with PHPUnit
7. Deploy to production (Laravel Forge, Vapor, or custom server)
---
## Data Flow
1. User searches for a city
2. Frontend sends request to backend
3. Backend checks MySQL cache:
- If cached and not expired: return cached data
- If not cached or expired: fetch from Wikipedia API, store in cache, return data
4. User selects a city
5. Backend fetches attractions:
- Check cache for OpenTripMap and Overpass data
- If expired, fetch fresh data and update cache
- Merge data from multiple sources
6. Frontend displays city info on map with markers
7. User interacts with map and attraction list

## Mobile App Integration
The backend API is designed to support a mobile application using Laravel Sanctum for token-based authentication.
### Mobile App Authentication Flow
1. **Registration:** POST /api/register → Returns user + token
2. **Login:** POST /api/login → Returns user + token
3. **Authenticated Requests:** Include token in header: `Authorization: Bearer {token}`
4. **Logout:** POST /api/logout → Revokes token
### Mobile App Features
- Browse and search cities (no auth required)
- View city details and attractions on map
- User registration and login
- Save favorite cities
- Create and manage trip itineraries
- Sync favorites and trips across devices
- Offline caching (handle on mobile side)
### CORS Configuration
Configure `config/cors.php` to allow requests from mobile app:
```php
'paths' => ['api/*'],
'allowed_origins' => ['*'], // Or specify mobile app origins
'allowed_methods' => ['*'],
'allowed_headers' => ['*'],
'supports_credentials' => false,
```
