SunEditor

SunEditor is a lightweight, fast, and extensible WYSIWYG (What You See Is What You Get) web editor built entirely with vanilla JavaScript. It is designed for creating structured content such as articles, documentation, and emails, focusing on consistency and content validation. The current stable version is 3.1.2, with the project actively maintained and receiving regular bug fixes and enhancements. A major rewrite in version 3.0.2 completely revamped the codebase, introduced a modular plugin system, and dropped support for Internet Explorer. SunEditor boasts no external dependencies, offers a responsive user interface, and is easily integrated into modern web application frameworks like React, Vue, and Svelte. Its rich plugin ecosystem includes features like advanced table editing, LaTeX support, drawing tools, code blocks with language selectors, Markdown view mode, and built-in media galleries. It distinguishes itself by providing a robust, highly customizable editing experience without the overhead of external libraries.
