bknd simplifies app development by providing fully functional backend for data management, 
authentication, workflows and media. Since it's lightweight and built on Web Standards, it can 
be deployed nearly anywhere, including running inside your framework of choice. No more 
deploying multiple separate services!

## ✨ Features
**📊 Data**: Define, query, and control your data with ease. 
  - Define entities with fields and relationships, synced directly to your database.  
  - Supported field types: `primary`, `text`, `number`, `date`, `boolean`, `enum`, `json`, `jsonschema`.  
  - Relationship types: `one-to-one`, `many-to-one`, `many-to-many`, and `polymorphic`.  
  - Advanced querying with the **Repository**: filtering, sorting, pagination, and relational data handling.
  - Seamlessly manage data with mutators and a robust event system.  
  - Extend database functionality with batching, introspection, and support for multiple SQL dialects.

**🔐 Auth**: Easily implement reliable authentication strategies.
  - Built-in `user` entity with customizable fields.  
  - Supports multiple authentication strategies:  
    - Email/password (with hashed storage).  
    - OAuth/OIDC (Google, GitHub, and more).  
  - Secure JWT generation and session management.

**🖼️ Media**: Effortlessly manage and serve all your media files.
  - Upload files with ease.  
  - Adapter-based support for S3, S3-compatible storage (e.g., R2, Tigris), and Cloudinary.

**🔄 Flows** (UI integration coming soon!): Design and run workflows with seamless automation.
  - Create and run workflows with trigger-based automation:  
    - Manual triggers or events from data, auth, media, or server actions.  
    - HTTP triggers for external integrations.  
  - Define tasks in sequence, parallel, or loops, with conditional execution.  
  - Use reusable sub-workflows to organize complex processes.  
  - Leverage OpenAPI specifications for API-based tasks.
