Ckeditor5
Что это такое?CKEditor 5 — это современный JavaScript-редактор форматированного текста (WYSIWYG) с MVC-архитектурой, собственной моделью данных и виртуальным DOM, написанный с нуля на TypeScript.
Это готовый редактор или фреймворк, чтобы собрать свой?И то, и другое: вы устанавливаете готовые пакеты редактора в своё веб-приложение, а CKEditor 5 одновременно является фреймворком для создания собственных решений для работы с форматированным текстом.
Как добавить его в свой проект?Установите npm-пакет (npm install ckeditor5) и соберите проект сборщиком вроде Vite, либо воспользуйтесь онлайн-конструктором CKEditor 5 Builder: выберите тип редактора и плагины и скачайте готовый пакет. Есть также официальные интеграции с Angular, React и Vue.
Нужно ли что-то особенное в моём стеке, например TypeScript или сборщик?Подходит обычный современный JavaScript-стек: для установки через npm нужен сборщик (рекомендуется Vite), а в официальных пакетах начиная с версии v37.0.0 идут нативные типы TypeScript.
Можно ли бесплатно использовать его в коммерческом продукте, или есть подвох?Подвох есть: проект распространяется по двойной лицензии — GNU GPL v2 или новее либо на коммерческих условиях от CKSource. Бесплатное использование означает соблюдение GPL; иначе нужна платная коммерческая лицензия.
Что редактор умеет из коробки?Совместное редактирование с комментариями и отслеживанием правок, таблицы, списки и стили шрифта, средства доступности, поддержка многих языков, ввод и вывод Markdown, правка исходного кода, экспорт в PDF и Word. Изображения и видео поддерживаются с разными системами загрузки и хранения.
Может ли ИИ-агент для кодинга настроить его за меня?Да. Установите официальное умение CKEditor — и агенты вроде Claude Code, Cursor, Codex или Copilot сами займутся установкой, настройкой и лицензированием.
Можно ли попробовать платные функции до оплаты?Да — зарегистрируйтесь на бесплатную 14-дневную пробную версию без обязательств и испытайте все возможности CKEditor 5, включая премиум-функции.
Какие редакторы можно с его помощью сделать?Что угодно — от редакторов в духе Google Docs или Medium до приложений вроде Slack или Twitter. В README сказано, что всё это возможно в рамках одного редакционного фреймворка.
What are similar projects?tinymce, tiptap, slate, quill, BlockNote, pell, lexical, draft-js
Which topics is it in?contenteditable, wysiwyg-editor, rich-text-editor, wysiwyg, text-editor, gpl, plugins, angular, gplv2, collaboration, monorepo, editor
