🛠️ Installation

1. Create the project

Use Composer to install the project:

composer create-project semhoun/slim-skeleton-mvc [your-app]

2. Configuration

1. Copy the .env.example file to .env:

cp .env.example .env

2. By default, the application uses a SQLite database located in var/database.sqlite. For production, configure your database and other settings in the .env file or via environment variables.

3. Initialize the database:

./console migrations:migrate

4. (Optional) Generate Doctrine proxies:

./console orm:generate-proxies

3. Run the application

You can use the PHP built-in development server:

composer start

Or use the console command:

./console serve

The application will be accessible at http://localhost:8080.

4. Available Console Commands

# Clear application cache
./console cache:clear

# Initialize cache
./console cache:init

# Generate Doctrine proxies
./console orm:generate-proxies

# Run development server
./console serve

# List all available commands
./console list

🧪 Development Tools

Run unit tests:

composer test

Check code quality with PHP Insights:

composer insights-check

Apply automatic Rector fixes:

composer rector-fix

Fix code style issues:

composer insights-fix

Run pre-commit checks (code style + rector + dos2unix):

composer pre-commit

A compose.yml file is provided to facilitate deployment. Here is a configuration example:

services:
  slim:
    image: semhoun/webserver
    ports:
      - "8080:80"
    volumes:
      - .:/www
    environment:
      - APP_ENV=dev
      - DEBUG_MODE=true

To launch the environment with Docker:

docker compose up -d

📝 Notes

• Ensure that the var folder has write permissions (for cache, logs, database)
• Default credentials: admin / admin (change in production!)
• The project includes an error rendering system (HTML/JSON) based on the Accept header
• API routes are prefixed with /api (configurable in config/settings/_base_.php)
