Progress bar

A progress bar communicates the status of a system process.

Install

One package and one stylesheet. The stylesheet carries the tokens every component reads.

pnpm add @wolf-rayet/react
import '@wolf-rayet/react/css/wolf-rayet.css';
import { ProgressBar } from '@wolf-rayet/react';

Props

A required prop is marked with an asterisk.

PropTypeDefaultDescription
valuenumber—How far along the work is, from 0 to 1. Leave it out when you cannot know, and the bar runs indeterminate instead.
appearance'default' | 'success' | 'inverse''default'Success marks work that finished. Inverse is for a bar sitting on a bold ground.
labelstring'Progress'Names the work for a screen reader. Say what is happening, as in Uploading files.

Accessibility

What the component does for you, and what it needs from you.

  • A bar with a value reports it, so a screen reader hears the fraction rather than a description of a rectangle.
  • An indeterminate bar says work is happening without claiming to know how much is left, which is the honest thing to announce.
  • The label is the accessible name and is required in practice, since Progress on its own does not say what is running.
