This package is created for people who using Chakra-UI's and react-markdown together.

CSSReset component is turning down every default style of elements that provided by browser. HTML elements like h1, h2, h3... aren't get default styles but Markdown need them for rendering purposes. This package is solving the problem by changing renderer defaults with chakra-ui's components.

• Install @chakra-ui/react by following their Getting Started - Chakra UI guide.
• Install react-markdown.
• Install chakra-ui-markdown-renderer.

$ yarn add chakra-ui-markdown-renderer
# or
$ npm i chakra-ui-markdown-renderer

import ChakraUIRenderer from 'chakra-ui-markdown-renderer';
<ReactMarkdown components={ChakraUIRenderer()} children={markdown} skipHtml />;

chakra-ui-markdown-renderer is merging standart theme with your theme by default.

import ChakraUIRenderer from 'chakra-ui-markdown-renderer';
const newTheme = {
  p: props => {
    const { children } = props;
    return (
      <Text mb={2} fontSize={'12px'}>
        {children}
      </Text>
    );
  },
};
<ReactMarkdown
  components={ChakraUIRenderer(newTheme)}
  children={markdown}
  skipHtml
/>;
