@inputcn/duration

90m, 1:30 and 1.5h are the same number.

Live demo · The contract · All 11 components

Accepts the three ways people actually write durations and emits seconds. multipleOf takes a duration too, so the message reads “must be a multiple of 15 minutes” rather than “must be a multiple of 900”.

Install

Recommended — copy the component source into your project, the way shadcn/ui does:

npx shadcn@latest add https://input-cn.vercel.app/r/duration-input.json

Or install the package and import it directly:

npm i @inputcn/duration

[!NOTE] Either way, import the stylesheet once in your app root:

import "@inputcn/core/styles.css"

Every colour and radius resolves from the shadcn CSS variables you already define, so it matches your theme with no configuration.

Usage

<DurationInput
  label="Session timeout"
  value={seconds}      // 5400
  onChange={setSeconds}
  min="30s"
  max="4h"
  multipleOf="15m"
  layout="segmented"   // or "text" | "presets"
/>

[!IMPORTANT] onChange emits the canonical value, never the formatted string.

| Type | Form | Example | |---|---|---| | number | seconds | 5400 |

Pass name and a hidden input carries that value, so FormData and Server Actions receive it too — with no client component.

What makes it different

• Three input styles. Free text, segmented h/m/s, or preset pills.
• ISO 8601 out too. The hook exposes PT1H30M alongside the seconds.

Validation

Rules are props. No schema, no resolver, no onBlur handler. Errors stay silent until the first blur, then clear the moment the value becomes valid.

| Prop | Type | Description | |---|---|---| | min? | DurationBound | — | | max? | DurationBound | — | | multipleOf? | DurationBound | Must be a whole multiple of this. Accepts "15m". | | maxUnit? | DurationUnit | Largest unit shown when formatting. Default "d". |

Every error element carries a data-rule attribute naming the rule that failed, so tests assert the rule rather than the sentence.

A matching Zod schema ships from a separate entry point, so Zod never enters your component bundle:

import { durationSchema } from "@inputcn/duration/schema"

Props

| Prop | Type | Description | |---|---|---| | bareUnit? | DurationUnit | What a bare number means. Default "m". | | presets? | readonly string[] | Presets offered by the presets layout. | | label? | ReactNode | Visible label. Supply this or aria-label — a field with neither has no accessible name. | | hint? | ReactNode | Helper text under the field. Replaced by the error message while one is showing. | | layout? | DurationLayout | PRD §6. text is fastest for keyboard users; segmented is unambiguous. | | showNormalised? | boolean | Show the normalised value as a trailing affix. Default true. |

Plus the 23 props every inputcn component implements identically — value, onChange, name, required, variant, size and the rest. See the props contract.

Accessibility

Keyboard complete, labelled, and errors announced once through role="alert" rather than on every keystroke. 50 axe-core checks run on every commit.

[!CAUTION] Screen readers have not been verified yet. Until they are, this library is structurally accessible, not screen-reader verified. The full audit, including what is untested and why, is in ACCESSIBILITY.md.
