React vs SvelteKit — Rich Text Explorer

Editor Availability by Framework

Editor	React	Svelte	Notes
ProseMirror	Wrappers	Direct use	Framework-agnostic core. Works everywhere.
Tiptap	Official	Community	React gets more attention. Svelte works but less polished.
CodeMirror 6	Wrappers	Direct use	Framework-agnostic. Easy to wrap in either framework.
Lexical	Official	No support	React-only by design. DecoratorNodes use React components.
Slate	Required	No support	Deeply coupled to React. Rendering IS React.
Plate	Required	No support	Built on Slate. Inherits React dependency.
BlockNote	Required	No support	React-only Notion-like editor.
Milkdown	Official	Official	Framework adapters for both. Equal support.
Editor.js	Wrappers	Direct use	Vanilla JS. Works anywhere.
Quill	Wrappers	Wrappers	Framework-agnostic core.

Developer Experience

React

Largest ecosystem of editor components
Most examples and tutorials target React
Hooks-based integration (useEditor, etc.)
Virtual DOM can conflict with editor DOM management
Need to be careful about re-renders
Mature but verbose component model

SvelteKit

Fewer ready-made editor wrappers
Direct DOM access via actions/onMount — cleaner integration
No virtual DOM conflicts
Smaller bundle overhead
Reactive stores work well with editor state
Less boilerplate, more concise

Integration Patterns

tsx

// React: useEditor hook (Tiptap)
import { useEditor, EditorContent } from '@tiptap/react';
import StarterKit from '@tiptap/starter-kit';

function MyEditor() {
  const editor = useEditor({
    extensions: [StarterKit],
    content: '<p>Hello</p>'
  });
  return <EditorContent editor={editor} />;
}

svelte

<!-- Svelte: onMount + bind (Tiptap/CodeMirror/ProseMirror) -->
<script>
  import { onMount } from 'svelte';
  let container;

  onMount(() => {
    // Direct DOM access — no virtual DOM conflicts
    const editor = new Editor({
      element: container,
      extensions: [StarterKit],
      content: '<p>Hello</p>'
    });
    return () => editor.destroy();
  });
</script>

<div bind:this={container}></div>

Verdict

When to choose React

You need Lexical, Slate, Plate, or BlockNote (React-only)
Your team already uses React
You need the largest possible ecosystem of editor components

When to choose SvelteKit

You're using framework-agnostic editors (CodeMirror 6, ProseMirror, Editor.js)
Bundle size matters
You want cleaner DOM integration (no virtual DOM conflicts)
You prefer less boilerplate and simpler reactivity
Your editor needs are standard (not needing React-specific features)

Our Recommendation

SvelteKit with CodeMirror 6 for markdown editing, and SvelteKit with Tiptap/ProseMirror for rich text. The framework-agnostic editors work beautifully with Svelte's direct DOM model. React-only editors (Lexical, Slate) are excellent but not worth switching frameworks for.
