Define a class inheriting from rx.State with typed class attributes as base vars, such as count: int = 0. Add computed vars with the @rx.var decorator and event handlers as methods decorated with @rx.event.

Create pages as functions decorated with rx.page or register them via app.add_page(). Dynamic routes use bracket syntax like [slug] in the route path to capture URL parameters.

Yes, Reflex includes built-in SQLModel integration for database tables. You define models, run queries, and set up relationships directly in Python, as covered in the database documentation at reflex.dev/docs/database/overview.

Yes, Reflex supports wrapping existing React components so they can be used as rx components in Python. The official guide at reflex.dev/docs/wrapping-react/overview explains the wrapping process and custom component publishing.

Event handlers must be methods on an rx.State class, and UI updates only occur when state vars change through those handlers. Use auto-generated set_<var> setters for simple updates and check the events documentation for chaining rules.
