Progress

Displays the status of a task that takes a long time.

"use client"

import * as React from "react"

import { Progress } from "@/components/ui/progress"

export function ProgressDemo() {
  const [value, setValue] = React.useState(20)

  React.useEffect(() => {
    const interval = setInterval(() => {
      setValue((current) =>
        Math.min(100, Math.round(current + Math.random() * 25))
      )
    }, 1000)
    return () => clearInterval(interval)
  }, [])

  return <Progress value={value} />
}

Installation


pnpm dlx shadcn@latest add https://coss.com/ui/r/progress.json

Usage

import {
  Progress,
  ProgressLabel,
  ProgressValue,
} from "@/components/ui/progress"

<Progress value={40} />

Note: If you render children inside Progress, you must also include ProgressTrack and ProgressIndicator inside it. Without them, the bar will not display. When no children are provided, a default track and indicator are rendered for you.

Examples

        <ProgressLabel>Export data</ProgressLabel>
        <ProgressValue />
      </div>

Comparing with Radix / shadcn

If you’re already familiar with Radix UI and shadcn/ui, this guide highlights the small differences and similarities so you can get started with coss.com ui quickly.

Quick Checklist

Prefer ProgressLabel and ProgressValue for label/value instead of inline elements
If you render children inside Progress, you must include ProgressTrack and ProgressIndicator (otherwise the bar will not display). Without children, a default bar is rendered for you
If you used asChild, switch to the render prop

Additional Notes

Base UI introduces separate parts — ProgressLabel, ProgressValue, ProgressTrack, and ProgressIndicator — which you compose inside Progress for greater flexibility.
