ContentTools is a free, open-source JavaScript library for building WYSIWYG editors for HTML content.
What ContentTools is
ContentTools is a free, open-source JavaScript library for building WYSIWYG editors for HTML content. Developers can add its CSS and JavaScript to a page and designate regions for in-place editing. The editing tools support inserting and converting content such as images, videos, tables, and lists. Users can move content blocks, resize images and videos, and undo or redo changes without a stated session limit. Developers can define style palettes for eligible elements. The library is framework agnostic and extensible; its five component libraries can be used independently. The maker describes integrations with CMS applications and frameworks including WordPress, Yii, Laravel, and Django. ContentTools does not store edited content, so an application needs a configured save mechanism. It also does not provide user authentication or function as a content management system. Its image upload, rotation, and cropping interface is shown in a demo that simulates the functionality without a server-side API. The project is MIT licensed, and its getting-started guide directs developers to pre-built files in the repository's build folder.
Good
- Free and MIT licensed
- Supports in-page editing of selected regions
- Provides unlimited undo and redo during a session
- Framework agnostic and extensible
Watch out
- Does not store edited content
- Does not provide user authentication
- Demo image uploads lack a server-side API
Who it suits
ContentTools suits developers building custom HTML editing experiences for web pages. It may be useful when a project needs an editor library that can be integrated with its own storage and authentication.
Verdict
ContentTools supplies editing components for developers rather than a complete content management system. Plan for your own content storage and authentication, and note the demo limitation around image uploads.
