svelte-keyboard

A svelte component for when you want a permanent, on-screen keyboard. View Demo.

Installation

npm install svelte-keyboard

Usage

<script>
  import Keyboard from "svelte-keyboard";

  const onKeydown = (event) => {
    console.log(event.detail);
  }
</script>

<Keyboard on:keydown="{onKeydown}" />

Localization Layouts

• qwerty - (default)
• azerty

Preset Layouts

• standard - (default) two pages with all basic keys
• crossword - one page, just capitalized letters and Backspace
• wordle - one page, just capitalized letters, Backspace, and Enter

Custom Layout

<script>
  const keys = [{ row: 0, value: "Q"}, ...];
</script>

<Keyboard custom="{keys}" />

If you want value to be different than the display key, pass a display property. If you want keys to be laid out on the second page, include page: 1 (defaults to page: 0) .

<Keyboard layout="wordle" />

Custom Styles

Use style props on the component (showing defaults):

<Keyboard
	--height="3.5rem"
	--background="#efefef"
	--color="currentColor"
	--border="none"
	--border-radius="2px"
	--box-shadow="none"
	--flex="1"
	--font-family="sans-serif"
	--font-size="20px"
	--font-weight="normal"
	--margin="0.125rem"
	--min-width="2rem"
	--opacity="1"
	--stroke-width="3px"
	--text-transform="none"
	--active-background="#cdcdcd"
	--active-border="none"
	--active-box-shadow="none"
	--active-color="currentColor"
	--active-opacity="1"
	--active-transform="none"
>

For any other properties, use global CSS on the selector .svelte-keyboard button.key. Note: stroke-width is for svg icons.

To give specific keys a class (e.g., "clicked") you can use the keyClass prop:

<Keyboard keyClass="{{ "x": "clicked"}}" />

The keyClass object is key/value pairs where they key is the key name (e.g., "x" or "Enter") and the value is the class name(s) to apply (e.g., "clicked" or "clicked hide"). You can then use global styling :global(.key.clicked) { ... } to apply custom styles.

Special values

• Backspace displays a backspace svg icon
• Enter displays an enter svg icon
• Space displays a spacebar
• Shift displays "ABC" or "abc" to toggle case, no event fires
• Page1 displays "123" and will switch to the second page, no event fires
• Page0 displays "abc" and will switch to the first page, no event fires

If you want to say the word instead of an icon, add this prop:

<Keyboard noSwap={["Enter"]} />
