Progress.

A clear sense of how far along.

In practice

Native progress element: set value and max for a determinate value, omit value for indeterminate progress. Always label it.

Installation

Install Coal once. Components and TypeScript declarations are included. React 19 and React DOM 19 are peer dependencies.

npm install http://localhost:3100/downloads/chlohal-coal-ui-0.5.0.tgz

This installs the local package. It is not yet published on npm. See installation for stylesheet setup and integration.

Usage

"use client";
import * as React from "react";
import "@chlohal/coal-ui/styles.css";
import { Progress } from "@chlohal/coal-ui";
export default function Example() {
    return (<div>
          <div>
            <span>Bringing it together</span>
            <span>68%</span>
          </div>
          <Progress value={68} aria-label="Project completion"/>
        </div>);
}

Source

The original Coal implementation. Use the package export to integrate it.

import * as React from "react";
import { cn } from "./internal.js";
export function Progress({
  className,
  ...props
}: React.ComponentPropsWithRef<"progress">) {
  return (
    <progress max={100} className={cn("coal-progress", className)} {...props} />
  );
}

Accessibility checklist

• Provide an accessible name for controls, including icon-only buttons.
• Check keyboard navigation, visible focus and disabled states in your application.
• Do not rely on color alone to communicate status.
