# What is a lumen?

Laravel Lumen is a micro-framework based on the Laravel framework, designed for building fast, lightweight, and efficient applications and APIs. Here are some key aspects of Laravel Lumen:

1. **Purpose**: Lumen is tailored for microservices and API development. It focuses on providing a minimalist framework that retains the essential features of Laravel without the additional overhead.
    
2. **Performance**: Because it strips away many of Laravel's features that are not essential for building APIs, Lumen can handle requests faster and with lower latency.
    
3. **Similarity to Laravel**: Lumen shares the same core components as Laravel, which means developers familiar with Laravel will find it easy to pick up and use Lumen. It retains a similar syntax and many of the same features, such as routing, middleware, and service providers.
    
4. **Components**: It includes essential components like:
    
    * **Routing**: For defining API endpoints.
        
    * **Middleware**: For filtering HTTP requests entering the application.
        
    * **Validation**: For ensuring the data passed to the API meets certain criteria.
        
    * **Eloquent ORM**: For interacting with the database.
        
    * **Queuing**: For background job processing.
