Timepicker Ui MCP Server

timepicker-ui

A time picker for web forms. Attach it to an <input> and users pick a time on a clock face or a scroll wheel.

Why timepicker-ui

• Zero dependencies.
• ~26 KB gzipped core. The range and timezone plugins are about 3-4 KB each, the wheel plugin about 9 KB, and a plugin only gets bundled if you import it (bundle stats).
• Clock, wheel or compact wheel (a small dropdown under the input).
• Plain JS API, so it works the same in React, Vue, Angular, Svelte or without a framework.
• Doesn't touch window or document on import, so it's safe in Next.js, Nuxt and other SSR setups.
• Keyboard and screen reader support. All texts, the screen-reader ones included, can be translated via labels.

Features

• 12h / 24h, hour and minute steps, disabled times
• Optional seconds (HH:MM:SS) in the clock, wheel and compact wheel
• 12 themes (Material 2/3, Crane, Dark, Cyberpunk, Blueprint, ...)
• Inline mode, clear button, mobile layout
• Time ranges and timezones via plugins
• TypeScript types included

Installation

npm install timepicker-ui

Quick start

<input id="timepicker" type="text" />

import { TimepickerUI } from "timepicker-ui";
import "timepicker-ui/main.css";

const input = document.querySelector("#timepicker");
const picker = new TimepickerUI(input, {
  clock: { type: "24h" },
  ui: { theme: "dark" },
  callbacks: {
    onConfirm: (data) => console.log("Selected:", data),
  },
});
picker.create();

No global CSS reset is needed: the picker sets box-sizing: border-box on its own elements (details).

API

picker.create();               // render the picker and attach it to the input
picker.open();
picker.close();
picker.destroy();
picker.getValue();             // { hour, minutes, seconds, type, time }, seconds only with clock.showSeconds
picker.setValue("14:30");      // "2:30 PM" works too
picker.setValue("14:30:15");   // with clock.showSeconds
picker.setOptions({ ui: { theme: "crane" } });

picker.on("confirm", (data) => {});
picker.on("cancel", (data) => {});
picker.on("open", () => {});
picker.on("update", (data) => {});
picker.on("clear", (data) => {});
picker.on("error", (data) => {});
picker.once("confirm", handler);
picker.off("confirm", handler);

TimepickerUI.getById("my-id");
TimepickerUI.getAllInstances();
TimepickerUI.isAvailable("#timepicker");
TimepickerUI.destroyAll();

Options

Grouped by area. Pass only what you need, the rest has defaults (full list).

new TimepickerUI(input, {
  clock: {
    type: "12h" | "24h" | "auto", // default "12h"; "auto" follows the browser locale
    incrementHours: 1,
    incrementMinutes: 1,
    showSeconds: false,         // true adds seconds (HH:MM:SS)
    incrementSeconds: 1,
    disabledTime: { hours: [], minutes: [], seconds: [], ranges: "" },
    defaultTime: "now" | { time, updateInput },
  },
  ui: {
    theme: "basic" | "dark" | "m3-green" | "crane" | "blueprint" | ...,
    mode: "clock" | "wheel" | "compact-wheel",   // default "clock"
    animation: true,
    backdrop: true,
    initialView: "clock",       // or "keyboard"
    editable: false,
    inline: { enabled: false, container: "#picker" | element, showButtons: false, autoUpdate: false },
    clearButton: false,         // or { clearInput: false } to keep the input value on Clear
    cssClass: "",
  },
  labels: { am, pm, ok, cancel, clear, clockTitle, hour, minute, second, rangeFrom, rangeTo, timezone, ... },
  behavior: { focusTrap: true, returnFocus: false, delayHandler: 0, id: "" },
  callbacks: { onConfirm, onCancel, onOpen, onUpdate, onSelectHour, onSelectMinute, onSelectSecond, onSelectPeriod, onClear, onError, ... },
  wheel: { placement: "auto" | "top" | "bottom", hideFooter: false, commitOnScroll: false, hideDisabled: false, ignoreOutsideClick: false },
  range: { enabled: false, minDuration, maxDuration },
  timezone: { enabled: false, default, list },
});

Themes

Preview all of them: basic, crane, crane-straight, m3-green, m2, dark, glassmorphic, pastel, ai, cyberpunk, blueprint, blueprint-dark.

main.css is required and already includes basic. The rest are separate files:

import "timepicker-ui/main.css";
import "timepicker-ui/theme-dark.css";

new TimepickerUI(input, { ui: { theme: "dark" } });

Or import timepicker-ui/index.css to get all of them. Writing your own theme: styling guide.

Plugins

Range, timezone and wheel ship as separate imports. Register them once before creating pickers. You need WheelPlugin for the wheel and compact-wheel modes.

import { TimepickerUI, PluginRegistry } from "timepicker-ui";
import { RangePlugin } from "timepicker-ui/plugins/range";
import { TimezonePlugin } from "timepicker-ui/plugins/timezone";
import { WheelPlugin } from "timepicker-ui/plugins/wheel";

PluginRegistry.register(RangePlugin);
PluginRegistry.register(TimezonePlugin);
PluginRegistry.register(WheelPlugin);

new TimepickerUI(input, { range: { enabled: true } });

Upgrading

From 4.4, 4.5 adds optional seconds (clock.showSeconds) and fixes many bugs. It also renames many options to clearer names, for example ui.initialView instead of ui.mobile, and adds setOptions() in place of update(). The old names keep working until 5.0, and the options page lists every pair. A few changes can affect an existing setup: the AM/PM part of the value is always AM / PM whatever labels.am / labels.pm say, out-of-range clock.disabledTime.ranges edges such as 25:00 are reported as errors, the old .tp-ui-ripple classes are gone, and some focus-ring and radius tokens changed. The CHANGELOG lists them under "Check before upgrading".

From 4.3 nothing breaks. 4.4 adds the blueprint and blueprint-dark themes, 16 new labels.* for screen-reader text, and Home/End/PageUp/PageDown keys. See the CHANGELOG.

From 3.x, options are now grouped (clock, ui, labels, ...), events go through picker.on(), and CSS class names changed. There's a migration guide.

From 2.x, you have to import the CSS yourself and some event names changed (legacy guide).

Frameworks

React:

import { useEffect, useRef } from "react";
import { TimepickerUI } from "timepicker-ui";
import "timepicker-ui/main.css";

function TimePicker() {
  const ref = useRef<HTMLInputElement>(null);
  useEffect(() => {
    if (!ref.current) return;
    const picker = new TimepickerUI(ref.current);
    picker.create();
    return () => picker.destroy();
  }, []);
  return <input ref={ref} />;
}

There's also a React wrapper (docs). Vue and Angular examples are in the quick start docs.

Coming in 5.0

5.0.0 is planned but has no release date yet. 4.5.0 prepares for it. Planned changes:

• Plugins will be built and registered differently. PluginRegistry.register(...) and the exported plugin types (PluginRegistry, Plugin, PluginManager, PluginFactory, TemplateProvider, ClearHandler, CoreState, EventEmitter) will change. The built-in range, timezone and wheel plugins stay. A migration guide ships with 5.0.
• CSS class names keep the tp-ui- prefix, but the part after it is reworked to follow Material Design component naming. Custom CSS that targets these classes will need updating. 5.0 ships a table of old and new names.
• The options renamed in 4.5.0 lose their old names, for example ui.mobile (now ui.initialView) and clock.smoothHourSnap (now clock.discreteHourJump). The options page lists every pair. The select:am / select:pm events go too (use select:period), and so does update() (use setOptions()).
• behavior.returnFocus becomes true by default: on close, focus goes back to the input, or to the data-open element that opened the picker. Set behavior.returnFocus: true now to return focus to the input.
• Code that is no longer needed is removed, including backward-compatibility paths for the deprecated items and dead code. This reduces bundle size and load cost for the core and each plugin. No size target is set yet. 4.5.0 already removes internal dead code that has no effect on the public API or markup. 5.0 removes the rest together with the items below.
• Items deprecated in 4.5.0 are removed:
  • OptionTypes (use TimepickerOptions)
  • clock.currentTime.locales
  • getValue().degreesHours and getValue().degreesMinutes
  • labels.toggleLabel, labels.format24Label, labels.timezoneSelectorLabel
  • the legacy focusInputAfterCloseModal option (use behavior.returnFocus)
  • the hide event and HideEventData (never emitted)
  • the range:get-disabled-time and range:update-disabled events (never emitted)
  • ErrorEventData.rejectedHour and rejectedMinute (always undefined)
• Also removed, because they do nothing or mislead:
  • internal events in the public TimepickerEventMap (range:minute:commit, animation:*) and its catch-all index signature, so on('typo') becomes a type error
  • behavior.delayHandler (it only delays closing and never debounced buttons)
  • TimepickerUI.isAvailable() (same as document.querySelector(...) !== null)
  • the undocumented DOM getters hour, minutes, okButton, cancelButton, clockHand
  • the callback arguments of open(cb) and destroy() in both forms, destroy(cb) and destroy({ callback }) (use once('open') or run the code after the call)
  • RangeManager, TimezoneManager and WheelManager exported from the plugin entry points (you can't get an instance today, and the new plugin API replaces them)
• Changed events and options:
  • select:hour, select:minute and select:second fire once when a value of their unit is picked, in every mode. Today, in clock mode, they fire when a field is activated, so picking an hour fires select:minute. To follow face changes, use switch:face, which 4.5.0 already emits
  • ui.footer replaces ui.inline.showButtons and wheel.hideFooter: false hides OK, Cancel and Clear in every mode, and true shows them in inline mode too
  • behavior.commitOnChange replaces ui.inline.autoUpdate and wheel.commitOnScroll: each picked value is written to the input and emits confirm, and the picker stays open
  • wheel.ignoreOutsideClick moves to behavior.ignoreOutsideClick and works in every mode, the clock modal included
  • the minute announcement reads labels.minute, so its default changes from Minutes to Minute
  • ui.cssClass is applied to one element instead of two
• Package and CSS:
  • the plugins no longer ship UMD builds (the UMD core never exposed PluginRegistry, so they could not be registered from a <script> tag). The core UMD build stays
  • about 50 CSS custom properties that no rule reads are removed, for example --tp-tertiary-container, --tp-on-tertiary-container, --tp-radius, --tp-hover-bg and 18 of the 34 --tp-size-* tokens. 5.0 lists them all
  • the ./plugins/* wildcard in package.json exports is removed, while ./plugins/range, ./plugins/timezone and ./plugins/wheel stay
  • crane-straight becomes a variant of crane with square corners (option name not decided)
  • ui.keyboardIcon / ui.clockIcon take an element or a factory function instead of an HTML string

Details are on the roadmap.
