remark plugin to compile Markdown as a Slate 0.50+ compatible object.

Usage

Slate object to Markdown:

remark-slate exports an opinionated serialize function that is meant to be invoked with a slate 0.50+ state object and will transform the object into a markdown document.

import { serialize } from 'remark-slate';

export default ({ onChange }) => {
  const [value, setValue] = useState(initialValue);

  const handleChange = useCallback((nextValue) => {
    setValue(nextValue);
    // serialize slate state to a markdown string
    onChange(value.map((v) => serialize(v)).join(''));
  }, [onChange]);

  return (
    <Slate editor={editor} value={value} onChange={handleChange}>
      <Editable
        renderElement={renderElement}
        renderLeaf={renderLeaf}
        placeholder="Enter some rich text…"
        ...
      />
      ...
    </Slate>
  );
};

Markdown to Slate object:

When deserializing from markdown to slate, this package is meant to be used with remark-parse and unified.

Our JS looks something like this:

import fs from 'fs';
import unified from 'unified';
import markdown from 'remark-parse';
import slate from 'remark-slate';

unified()
  .use(markdown)
  .use(slate)
  .process(fs.readFileSync('example.md'), (err, file) => {
    if (err) throw err;
    console.log({ file });
  });

And example.md looks like this:

# Heading one

## Heading two

### Heading three

#### Heading four

##### Heading five

###### Heading six

Normal paragraph

_italic text_

**bold text**

~~strike through text~~

> A block quote.

- bullet list item 1
- bullet list item 2

1. ordered list item 1
1. ordered list item 2

Results in the following Slate object
