commonmark-react-object-renderer

Renderer for CommonMark which returns a React description object

This renders a "description" of a React element which can be then used for rendering, e.g. with react-from-object. It's especially useful for passing rendered markdown from server to the client.

Example

import { Parser } from 'commonmark';
import Renderer from 'commonmark-react-object-renderer';
 
const parser = new Parser();
const renderer = new Renderer();
 
const input = `
# This is a header
 
And this is a paragraph
`;
const ast = parser.parse(input);
const result = renderer.render(ast);
 
assert.deepStrictEqual(result, {
  type: 'div',
  children: [
    {
      type: 'h1',
      children: ['This is a header'],
    },
    {
      type: 'p',
      children: ['And this is a paragraph'],
    },
  ],
});

Methods

Each instance of Renderer has these methods:

render(ast)

Returns the rendered markdown in the React element "description" format.

The first argument should be the ast as returned by the commonmark parser.

Options

Options can be passed as the first argument to the Renderer constructor, e.g. new Renderer(options).

renderers

This object should contain properties named after the possible node types as returned by the commonmark parser. Those include: block_quote, code_block, code, document, emph, heading, html_block, html_inline, image, item, linebreak, link, list, paragraph, softbreak, strong, text, thematic_break.

Each property should be a function that takes two arguments, in the following order:

  • The node, as returned by the commonmark parser (for possible properties please refer to the documentation)
  • The newly created element in an initial (empty) state

Those functions should return the rendered element, which can be either the modified second argument or a completely new object.

For an example usage please refer to the tests.
