timescape

A powerful, headless library that elegantly fills the void left by HTML's native <input type="time"> and <input type="date">.

Crafted in TypeScript, timescape is your toolkit to build custom date and time input components, masterfully managing the complexities of date and time data. The design and presentation are entirely in your hands, with timescape offering extensive support for a variety of libraries.

Key features such as accessibility and keyboard navigation are at the core of timescape, allowing you to focus on creating user-centric date and time inputs that integrate seamlessly into your projects.

See Storybook or check out the examples of how to use it + StackBlitz ⚡️ for more demonstrations.

Features

• 🧢 Headless Architecture: You control the UI – timescape handles the logic.
• 🧩 Framework Compatibility: Adapters for React, Preact, Vue, Svelte, and Solid.
• ⚙️ Flexible API️: Hooks (or equivalents) return getters for seamless component integration. Order of inputs (i.e. format) is completely up to you by just rendering in the order you prefer.
• 👥 Accessibility: Full A11y compliance, keyboard navigation and manual input.
• ⏰ Date and time flexibility: Supports min/max dates and 24/12 hour clock formats.
• 🪶 Lightweight: No external dependencies.
• 🔀 Enhanced input fields: A supercharged <input type="date/time">, offering additional flexibility.
• 🤳 Touch device support: Use it on any device, including touch devices.

Options

The options passed to timescape are the initial values. timescape returns the options either as store/signal or with an updater function (depending on the library you are using).

type Options = {
  date?: Date
  minDate?: Date | $NOW // see more about $NOW below
  maxDate?: Date | $NOW
  hour12?: boolean
  wrapAround?: boolean
  digits?: 'numeric' | '2-digit'
  snapToStep?: boolean
}

$NOW value

$NOW is a convenience value you can use for minDate and maxDate. It represents the current date and time at the moment of the user's interaction, dynamically adjusting to always reflect the current datetime value. This means you don't need to manually update it, as it always keeps itself current.

$NOW is exported as a constant for better type safety. By doing so, it eliminates the need for casting it as const, which would be required if $NOW were simply a string."

It can be imported from the package like so:

import { $NOW } from 'timescape'

// or from a specific module
import { $NOW } from 'timescape/react'

// Svelte import names prohibit a $ prefix, so it's renamed to NOW there
import { NOW } from 'timescape/svelte'

placeholder on input elements

The placeholder attribute on the input elements is supported and will be used to display the placeholder text. Usually it's to indicate the expected format of the input, e.g. yyyy/mm/dd

step on input elements

The step attribute on the input elements is supported and will be used to increment/decrement the values when the user uses the arrow keys. The default value is 1, but you can set it to any value you want. Also see snapToStep if you want to snap to the nearest step.

Ranges

timescape supports ranges for the date/time inputs. This means a user can select a start and end. This is useful for things like booking systems, where you want to allow the user to select a range of dates.

This is achieved by using two timescape instances, one for the start and one for the end. You can set their options independently, and they return the respective options and update functions in the from and to objects.

Example usage (this works similar for all supported libraries):

import { useTimescapeRange } from 'timescape/react'
// Use `createTimescapeRange` for Svelte

const { getRootProps, from, to } = useTimescapeRange({
  from: { date: new Date('2000-01-01') },
  to: { date: new Date() },
})

return (
  <div {...getRootProps()}>
    <div>
      <input {...from.getInputProps('days')} />
      <span>/</span>
      <input {...from.getInputProps('months')} />
      <span>/</span>
      <input {...from.getInputProps('years')} />
    </div>
    <div>
      <input {...to.getInputProps('days')} />
      <span>/</span>
      <input {...to.getInputProps('months')} />
      <span>/</span>
      <input {...to.getInputProps('years')} />
    </div>
  </div>
)

Anatomy & styling

The component is designed to be as un-opinionated as possible, so it doesn't come with any styling out of the box. You can style it however you want, but here are some tips to get you started.

This is how it could look like:

A typical anatomy of a timescape component may look like this:

HTML

<div class="timescape">
  <!-- Date inputs -->
  <input />
  <span class="separator">/</span>
  <input />
  <span class="separator">/</span>
  <input />

  <span class="separator">&nbsp;</span>

  <!-- Time inputs -->
  <input />
  <span class="separator">:</span>
  <input />
  <span class="separator">:</span>
  <input />
</div>

CSS

/**
 * Root element
 */
.timescape {
  display: flex;

  gap: 1px;
  width: fit-content;
  border: 1px solid #b2b2b2;
  padding: 5px;
  user-select: none;
  border-radius: 10px;
}

.timescape:focus-within {
  outline: 1px solid #8f47d4;
  border-color: #8f47d4;
}

/**
 * Date and time input elements
 */
.timescape input {
  /* This is an important style, as it ensures that the inputs have
  the same width regardless of the number of characters they contain. */
  font-variant-numeric: tabular-nums;
  height: fit-content;
  /* These are handled by the `:focus` selector */
  border: none;
  outline: none;
  cursor: default;
  user-select: none;
  box-sizing: content-box;
  /* For touch devices where input fields are not set to readonly */
  caret-color: transparent;

  /* For the calculation of the input width these are important */
  font-family: inherit;
  font-size: inherit;

}

.timescape input:focus {
  background-color: #8f47d4;
  color: #fff;
  border-radius: 6px;
  padding: 2px;
}

/**
 * Separator elements
 */
.timescape .separator {

  color: #8c8c8c;
  margin: 0;
}
