The decision inside it

The meter goes past the limit

A bar that clamps at 100% hides the only number that matters in the week it matters. The scale is whichever is larger, the allowance or where this ends, so an overage is drawn as an overage.

When to use it

Use Usage & Overage for metered usage: used against what's included, where the period is heading, the day it crosses the limit and what the overage will cost (rates in cents per unit block).

Installation

How you get it

Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.

Use Liro's Usage & Overage for this.
Install it: npx shadcn@latest add @liro/usage-meter
(the @liro registry is set up in components.json, with LIRO_KEY in .env.local)
Import it from @/components/ui/usage-meter.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.

For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Free components install through the @liro registry with your CLI token: see the Namespaced tab.

Usage

components/api-usage.tsx
import { UsageMeter } from "@/components/ui/usage-meter";

export function ApiUsage() {
  return (
    <UsageMeter
      title="API calls"
      unit="calls"
      included={100_000}
      used={72_400}
      day={18}
      daysInPeriod={30}
      periodEnd="14 Nov"
      overage={{ per: 1000, price: 20 }}
    />
  );
}

Props

Read from the component’s own TypeScript interface when the site is built, so this table cannot drift from the file you install.

Accessibility

  • Keyboard reachable throughout, in visual order
  • Focus trapped in overlays, Escape closes them
  • Focus returns to whatever opened it
  • Live regions announce what changed, not that something did
  • Honours prefers-reduced-motion

Responsive behavior

  • Sizes to its container, not the viewport
  • Usable from 320px up
  • Pointer-based interaction, so trackpad and touch both work
  • No hover-only affordances
