notion-block-renderer

v2.0.x ~: isNextJS of main props was removed.

v2.3.x ~: Added new block type table_of_contents.

This package is suitable for use with Reactjs or Nextjs. Notion blocks are rendered into React components. That component has a CSS class name corresponding to the block type.

I'm a programmer (@takumafujimoto). I first created this feature for myself. Later, I thought it would be useful for everyone, so I made it public.

Available Blocks

Code Block Usage

By default, code blocks are unstyled. The option isCodeHighlighter can be used to easily set the style.

This package defaults to react-syntax-highlighter when isCodeHighlighter is true. Use.

const Sample = ({ blocks }) => {
    return (
        <div>
            <NotionBlocks
                blocks={blocks}
                isCodeHighlighter={true}
            />
        </div>
    );
}

You can also set custom style CSS for the syntaxHighlighterCSS option.

You can choose to provide

• your own CSS or
• use react-syntax-highlighter's style.

react-syntax-highlighter style usage

Only Highlight.js of react-syntax-highlighter(not Prism.js) is supported at this time. So please use to import from "react-syntax-highlighter/dist/cjs/styles/hljs". See: https://react-syntax-highlighter.github.io/react-syntax-highlighter/demo/

First you need to install react-syntax-highlighter.

https://www.npmjs.com/package/react-syntax-highlighter

Then import styles to use.

import {
  monokaiSublime,
  irBlack,
  tomorrowNightBright,
  monokai,
} from "react-syntax-highlighter/dist/cjs/styles/hljs";

const Sample = ({ blocks }) => {
    return (
        <div>
            <NotionBlocks
                blocks={blocks}
                isCodeHighlighter={true}
                syntaxHighlighterCSS={monokaiSublime}
            />
        </div>
    );
}

your own CSS style usage

syntaxHighlighterCSS has the following type.

{
    [key: string]: React.CSSProperties;
}

Props

The NotionBlocks component has several props.

type

The props type for blocks is as follows. This is just a reference code. See currect type: types.ts.

type BlocksProps = {
  blocks: BlockType[];
  prefix?: string;
  blockPrefix?: string;
  blocksPrefix?: string;
  isCodeHighlighter?: boolean;
  syntaxHighlighterCSS?: {
    [key: string]: React.CSSProperties;
  };
};

The BlockType is our original declarative type. The best way may refer to @notionhq/client's type. Replacing code would be taking time. So please contribute if you can.
