Progress

Progress is used to display the progress status for a task that takes a long time or consists of several steps.

python
import reflex as rx

Basic Example

rx.progress expects the value prop to set the progress value. width is default to 100%, the width of its parent component.

python
rx.vstack(
    rx.progress(value=0),
    rx.progress(value=50),
    rx.progress(value=100),
    width="50%",
)

For a dynamic progress, you can assign a state variable to the value prop instead of a constant value.

python
import asyncio


class ProgressState(rx.State):
    value: int = 0

    @rx.event(background=True)
    async def start_progress(self):
        async with self:
            self.value = 0
        while self.value < 100:
            await asyncio.sleep(0.1)
            async with self:
                self.value += 1


def live_progress():
    return rx.hstack(
        rx.progress(value=ProgressState.value),
        rx.button("Start", on_click=ProgressState.start_progress),
        width="50%",
    )
