New Public API for wrapping Components
To make wrapping components easier and less error prone, the following functions should be overridden when wrapping components:
* `add_style` - return an `rx.style.Style` for default component styles
* `add_imports` - return a dictionary of `{"library-name0.5.0": {"tag1", "tag2", "tag3"}}` of required imports -- it will automatically be merged with the other component imports.
* `add_hooks` - return a list of javascript snippets that will go inside the component function -- it will be deduped automatically with any other hooks
* `add_custom_code` - return a list of javascript snippets that will go inside the module for each page the component is included in.
With these new methods, Reflex will internally call them for each parent class your component inherits from, so there is no need to call `super().add_*` or do any merging yourself.

Experimental Toast Component

def try_some_toast():
return rx.fragment(
rx.button("🥂", on_click=rx._x.toast.info("Cheers"), variant="outline"),
rx._x.toast.provider(),
)

Generic `.throttle` and `.debounce` for all Event types
python
class ThrottleState(rx.State):
last_event: datetime.datetime = datetime.datetime.now()
def handle_mouse_move(self):
self.last_event = datetime.datetime.now()
def throttle_example():
return rx.box(
ThrottleState.last_event,
background_color=rx.color("red", 7),
width="500px",
height="500px",
on_mouse_move=ThrottleState.handle_mouse_move.throttle(500), one event every 500ms
)
* Implement `throttle` and `debounce` as event actions by masenf in https://github.com/reflex-dev/reflex/pull/3091
`rx.container` new prop `stack_children_full_width`
For a nice streamlit-like wide layout, use the following snippet:
python
def index():
return rx.container(
rx.vstack(content()),
stack_children_full_width=True,
)
This will cause all vstack/hstack children and most stack child components to have `width="100%"` automatically, which provides a nice aesthetic for many apps without applying CSS to individual components.
