The architecture of reflex is fundamentally built around a reactive, component-based paradigm, enabling Python developers to create full-stack web applications. The core design principles revolve around a clear separation of concerns while maintaining tight integration for seamless data flow and UI updates.
This is the central orchestrator of a Reflex application. It manages the application's lifecycle, registers pages, handles global exception handlers, and coordinates the compilation and serving processes. It acts as the primary entry point for defining and running a Reflex app, integrating the FastAPI backend and SocketIO for real-time communication. It also ensures the development environment is correctly set up by interacting with prerequisites.
Related Classes/Methods:
Responsible for loading, managing, and providing access to application-wide configurations. This includes environment variables, database settings, and logging levels. It ensures that all parts of the application operate with consistent and correct settings, acting as a single source of truth for application parameters.
Related Classes/Methods:
The core of Reflex's reactivity. It defines how application data is stored, updated, and accessed using reactive variables (Var and ComputedVar). It manages state persistence (in-memory, disk, or Redis) and tracks changes to trigger automatic UI updates, forming the backbone of the application's dynamic behavior.
Related Classes/Methods:
Defines and processes all user interactions and backend logic triggers. It provides the mechanisms for defining event handlers that modify the application state in response to actions (e.g., button clicks, form submissions). It ensures that user actions are translated into state changes, driving the application's interactivity.
Related Classes/Methods:
Provides the foundational classes and utilities for building all user interface elements in Reflex. It defines how components are created, rendered, manage their properties, and handle their internal logic and dependencies. This component also integrates the styling system, managing visual properties, color modes, and converting Python styles to frontend-compatible CSS.
Related Classes/Methods:
The engine that translates Python-defined Reflex components and state into a runnable frontend application (React/JavaScript). It handles code generation for pages, components, state contexts, and themes, resolving imports and optimizing the output for deployment. It also includes utilities for packaging, file system operations, and executing external commands necessary for the build process.

Provides an abstraction layer for interacting with databases, primarily using SQLModel/SQLAlchemy. It handles database engine creation, session management, and migration capabilities, allowing developers to define and interact with database models directly within their Reflex application, ensuring data persistence.
