Easy-to-use Markdown editor, born to adapt to different application scenarios
Vditor is a browser-side Markdown editor, Support WYSIWYG, instant rendering (similar to Typora) and split-screen preview mode. It is implemented using TypeScript and supports native JavaScript and frameworks such as Vue, React, Angular, and Svelte..
Welcome to Vditor Official Site to learn more.
With the popularization of Markdown typesetting methods, more and more applications begin to integrate the Markdown editor. The current status of mainstream integrable Markdown editors is as follows:
- Some only support split-screen preview, that is, the editing area and preview area are separated
- Some support WYSIWYG and split-screen previews at the same time, but they cannot fully support Markdown syntax typesetting in WYSIWYG mode
- There is almost no instant rendering similar to Typora
These three points correspond to three application scenarios:
- Split screen preview: adapt to the traditional Markdown usage scene, suitable for editing and typesetting on a large screen
- WYSIWYG: Friendly to users who are not familiar with Markdown, users who are familiar with Markdown can also use it seamlessly
- Instant rendering: In theory, this is the most elegant Markdown editing method, allowing users familiar with Markdown to focus more on content creation
Therefore, a Markdown editor that can adapt to application scenarios is essential, it needs to consider:
- Use scenes of traditional Markdown users, providing split screen preview
- Rich text editing users' usage scenarios, providing WYSIWYG
- High-end Markdown users' use scenes, providing instant rendering
Vditor has made efforts in these areas, hoping to make some contributions to the modern general Markdown editing field.
- Support three editing modes: WYSIWYG(wysiwyg), Instant Rendering(ir) and Split View(sv)
- Support outline, mathematical formulas, mind maps, charts, flowcharts, Gantt charts, timing charts, staffs, multimedia, voice reading, heading anchors, code highlighting and copying, graphviz rendering
- Built-in security filtering, export, image lazy loading, task list, multi-platform preview, multi-theme switching, copy to WeChat/zhihu function
- Implementation of CommonMark and GFM specifications, formatting and syntax tree viewing of Markdown, and support for 10+ configurations
- The toolbar contains 36+ items of operations. In addition to support for expansion, the shortcut keys, tip, tip positions, icons, click events, class names, and sub-toolbars can be customized
- Extend auto-complete for emoji/@/# and so on
- You can use drag and drop, paste and paste to upload, display real-time upload progress, support CORS cross-domain upload
- Save content in real time to prevent accidental loss
- Recording support, users can directly publish voice
- The markup HTML is automatically converted to Markdown, if the paste contains images of external links, it can be uploaded to the server through the specified interface
- Support main window size drag and drop, character counting
- Multi-theme support, built-in black, white and green three sets of themes
- Multi-language support, built-in Chinese, English, Korean text localization
- Support mainstream browsers, mobile friendly
WYSIWYG mode is more friendly to users who are not familiar with Markdown, and you can use it seamlessly if you are familiar with Markdown.
Instant Rendering mode should not be unfamiliar to users who are familiar with Typora. In theory, this is the most elegant Markdown editing method.
The traditional Split View mode is suitable for Markdown editing on a large screen.
- All CommonMark syntax: Thematic breaks, ATX headings, Setext headings, Indented code blocks, Fenced code blocks, HTML blocks, Link reference definitions, Paragraphs, Block quotes, Lists, Backslash escapes, Entity and numeric character references, Code spans, Emphasis and strong emphasis, Links, Images, Raw HTML, Hard line breaks, Soft line breaks, and Textual content.
- All GFM syntax: Tables, Task list items, Strikethrough, Autolinks, XSS filtering
- Common Markdown extended syntax: Footnotes, ToC, Custom Heading ID
- Chart syntax
- Flow chart, sequence diagram, Gantt chart, supported by Mermaid
- Graphviz
- Line chart, pie chart, brain chart, etc., supported by ECharts
- Stave: supported by abc.js
- Math formulas: Math formula blocks, row-level math formulas, supported by MathJax and KaTeX
- YAML Front Matter
- Chinese context optimization
- Insert space between Chinese and Western
- Terminology spelling correction
- Chinese followed by English comma period and other punctuation are replaced with Chinese corresponding punctuation
Most of the above features can be enabled or disabled through the switch configuration, developers can choose to match according to their own application scenarios.

Due to the on-demand loading mechanism, the default CDN is https://unpkg.com/vditor@version number
If the code is modified or you need to use a self-built CDN, you can follow the steps below:

In the initial stage of developing Sym, we directly used WYSIWYG rich text editor. At that time, HTML-based editors were very popular, and it was very convenient to quote them in the project, which also conformed to the usage habits of users at that time.
Later, the rise of Markdown gradually changed everyone's typography. In addition, several of our other projects are for programmer users, so it is also a general trend to migrate to md. We chose CodeMirror, which is an excellent editor, it provides a rich programming interface for developers, and is also compatible with various browsers. it is good.
Later, as the business needs of our projects have precipitated, using CodeMirror sometimes feels more "cumbersome." For example, to implement @automatically complete the user name list, insert Emoji, upload files, etc., it requires more in-depth secondary development, and these business requirements are precisely common and necessary in many project scenarios.
Finally, we decided to start implementing the editor ourselves in Sym. With the iterations of several versions, Sym's editor has matured.
