notion-blocks-to-markdown

Converts Notion BlockObjectResponse[] or RichTextItemResponse[] to markdown.

In contrast to notion-to-md, this package does not automatically fetch unresolved children. Fetcing blocks from Notion is left to the user, and if some blocks have unresolved contents, a message will be displayed instead.

Usage

import { Client as NotionClient } from "@notionhq/client";
import {
  notionBlocksToMarkdown,
  notionRichTextItemsToMarkdown,
} from "notion-blocks-to-markdown";

const notionClient = new NotionClient({
  auth: process.env.NOTION_API_KEY,
});

const response = await notionClient.blocks.children.list({
  block_id: args.block_id,
});

const markdown = notionBlocksToMarkdown(blocks, {
  headingStartingLevel: 2,
  cleanOutput: true,
  noHtml: false,
});

const markdown = notionRichTextItemsToMarkdown(blocks[0].heading_1.rich_text, {
  noHtml: false,
});

Supported block types

Here is a list of the supported block types at this point, feel free to open a PR if you'd like to expand this list.

Block type	Support
heading_1	✅
heading_2	✅
heading_3	✅
paragraph	✅
bulleted_list_item	✅
numbered_list_item	✅
table_row	✅
quote	✅
to_do	❌
toggle	❌
equation	❌
code	✅
callout	❌
divider	✅
breadcrumb	❌
table_of_contents	❌
image	✅ Only if image.type === "external"
video	✅ Only if video.type === "external"

... there are a lot more types, but not all of them makes sense to convert to markdown.

Colors

Coloring the text in notion will result in a <span className="blue" />. So you'll have to write some CSS in order to get the colors you want. If you don't want this, you can use the noHtml: true option.

Notes

Fetching the BlockObjectResponse[] is left to the user of this package. If a BlockObjectResponse with has_children === true, a simple string...

"Block has unresolved children"

...will show up in markdown. You can hide these warnings using the cleanOutput: true option.
