Installation

1. Clone the repository

   git clone <repository-url>
   cd evwiki
   

2. Install dependencies

   composer install
   

3. Configure environment

   cp .env.local.example .env.local
   

   Edit .env.local and set your MongoDB connection:

   APP_ENV=dev
   APP_SECRET=your-secret-key-here
   MONGODB_URI=mongodb://localhost:27017
   

4. Start MongoDB Make sure MongoDB is running on your system.

5. Seed the database

   php bin/console app:seed-data

API Endpoints

Search

• GET /api/search?query={term} - Search for vehicles, brands, or models

• GET /api/brands/{brandId}/models - Get models for a specific brand

Models

• GET /api/models/category/{category} - Get models by category

Architecture

This application follows clean architecture principles:

Domain Layer

• Documents: MongoDB document models (Brand, CarModel, CarRevision)
• Repositories: Data access interfaces

Application Layer

• Services: Business logic (CarSearchService)
• Commands: Console commands for data management

Infrastructure Layer

• Controllers: HTTP request handlers
• Templates: Twig templates for rendering

Key Design Principles

1. SOLID Principles: Each class has a single responsibility
2. Dependency Injection: All dependencies are injected via constructor
3. No Else Statements: Code uses early returns for better readability
4. Readable Names: Self-documenting code with descriptive names

Development

Adding New Data

Use the seed command to populate the database:

php bin/console app:seed-data

Console Commands

List all available commands:

php bin/console list

Database Operations

The application uses MongoDB with Doctrine ODM. All database operations are handled through repositories following the Repository pattern.

Styling Guidelines

• No External CSS Frameworks: Pure CSS following modern standards
• Responsive Design: Mobile-first approach
• Modern UI: Clean, minimalist design inspired by search engines
• Accessibility: Semantic HTML and proper contrast ratios

Contributing

1. Follow PSR-12 coding standards
2. Write clean, self-documenting code
3. Use dependency injection
4. Follow SOLID principles
5. Avoid else statements
6. Use meaningful variable and method names
