@matrajs/svelte

Svelte bindings for Matra: a use: action and a store that follows the editor.

npm i @matrajs/core @matrajs/svelte

<script>
  import { starterKit } from '@matrajs/core'
  import { matra } from '@matrajs/svelte'

  const { action, editor, state } = matra({
    extensions: starterKit,
    content: '<p>Hello</p>',
  })
</script>

<button onclick={() => editor.commands.toggleBold()}
        aria-pressed={$state.isActive('bold')}>
  Bold
</button>

<div use:action></div>

What it adds

Svelte already has the right shape for this — an action runs when the element exists and is told when it goes away — so the binding is thin on purpose. What it adds over eight lines written inline is the two things people get wrong:

• The double-mount guard. A component rendered twice, or an action re-run by a hot reload, would otherwise attach a second view to one element, which is two carets fighting over it.
• A store. $state republishes on every change and every selection move, so a toolbar's pressed states come from the document rather than from what was last clicked.

The editor is created immediately rather than on mount, so commands, getJSON() and getText() all work before anything is on screen — which is what a server render and a test both need.

Svelte 4 and 5

Stores, not runes, so the same package works in both. A rune-only build would be a version boundary in exchange for nothing: $state on a store reads identically.
