ContentTools
What it is
ContentTools is a free, open-source JavaScript library for adding WYSIWYG editing to HTML pages. Developers include its CSS and JavaScript files, mark selected page regions as editable, and initialize the editor from those regions. Editing controls shown in the demo handle inserting and converting images, videos, tables, and lists. Users can drag content blocks into new positions, resize images and videos, and use unlimited undo and redo during an editing session. An image interface supports uploading, rotating, and cropping, although the demo simulates those actions without a server-side API. ContentTools is framework agnostic and extensible, and its five libraries can be used independently. The maker describes integrations with WordPress, Yii, Laravel, and Django, including a Django REST Framework tutorial. The editor emits a saved event so an application can send changed content to its own server. Developers must provide storage, authentication, and broader content-management functions.
