A markdown Previewer Component Supporting Auto-Scroll

A problem of most online markdown previewer is simply that the previewer does not follow the cursor.
This previewer solves that problem by unist and remark.

This previewer is a React Component providing markdown compied VDOM and auto-scroll feature. Therefore, you can style it by css or by the provided interface props.styles.

Demo

See Demo at github pages, styled by skeleton.css.

Usage

Just like other npm package

npm i --save remark-react-previewer

Then you can put the following code in JSX.

<Previewer
    cursorPosition = {line, column}
    markdown = {string}
    />

For customizing styles, you could use css or pass an styles:{tagName:cssInJS} to props.

• props.styles CSS in JS like Radium to style elements.
  props.styles should be a nested Object like props.styles = {tagName: cssInJS}, where the tagName is
  1. li, h1 and other html tags
  2. root for the root div
  3. scrolled for the cursor matched element.

On the Plan

• [ ] Passing a callback function for smoothie scroll~
• [ ] FootNote Support
• [ ] Clever Scroll for Code and Blockquote
• [ ] Editor Support as neovim-extension. (Will be another package)
• [ ] After Editor Support, A greasemonkey plugin for render markdown in rich-text editors like in quora and zhihu.

For someone want to rebuild auto-scroll previewer on other frameworks

I write an unist plugin to find the mdast node matching the cursor. You may like it~
