ProMarkdown

Introduction

ProMarkdown is a professional grade React markdown editor based on CodeMirror, for programmers and professional tech writters.

Github home

It provides following features for more sophiscated markdown editing:

• Frontmatters, YAML / TOML /JSON, which is the main reason for developing ProMarkdown
• Keymap, Vim / Sublime / Emacs, and obviously default
• Line numbers
• Block folding
• Preview / Fullscreen / Editing and live preview
• Search and replace
• I18n, with build zh-CN ( Simplified Chinese ) suppport. Developers can provide custom phrases for menu tips / search / replace labels.
• Toolbar / menu: a default menu supporting major markdown formats
• Extensible - it exposes underlying CodeMirror instance and allows you to plugin your own menu, custom preview and low level CodeMirror eventhandlers.

renderPreview?: (props: { value: string, frontmatter: string }) => React.ComponentElement<any, any> // Your custom preview component

The value is the editor's entire content, including frontmatter. You need to parse the value on your own. The preset frontmatter is passed in, with values of yaml-frontmatter or toml-frontmatter or json-frontmatter
