Quick start

npm install stilo-editor

<div id="toolbar"></div>
<div id="editor"></div>

import 'stilo-editor/style.css';
import { Editor, defaultExtensions } from 'stilo-editor';
import { createToolbar } from 'stilo-editor/ui';

const editor = new Editor({
  element: document.querySelector<HTMLElement>('#editor')!,
  extensions: [defaultExtensions()],
  content: '<p>Hello <strong>world</strong></p>',
});

createToolbar(editor, { container: document.querySelector<HTMLElement>('#toolbar')! });

editor.getHTML(); // '<p>Hello <strong>world</strong></p>'

✅ That is the whole setup.

Want your own UI?

Skip the toolbar: the core is headless.

import 'stilo-editor/content.css';
import { Editor, defaultExtensions } from 'stilo-editor';

const editor = new Editor({
  element: document.querySelector<HTMLElement>('#editor')!,
  extensions: [defaultExtensions()],
});

document.querySelector('#bold')!.addEventListener('click', () => editor.commands.toggleBold());
document.querySelector('#undo')!.addEventListener('click', () => editor.commands.undo());

Commands, button states and events: API reference.
