Martian: Markdown to Notion Parser

Convert Markdown and GitHub Flavoured Markdown to Notion API Blocks and RichText

Martian is a Markdown parser to convert any Markdown content to Notion API block or RichText objects. It uses unified to create a Markdown AST, then converts the AST into Notion objects.

Designed to make using the Notion SDK and API easier.

Supported Markdown Elements

• All inline elements (italics, bold, strikethrough, inline code, hyperlinks)
• Lists (ordered, unordered, checkboxes)
• All headers (header levels >= 3 are treated as header level 3)
• Code blocks (treated as paragraphs)
• Block quotes (treated as paragraphs)

Usage

import {markdownToBlocks, markdownToRichText} from '@instantish/martian';
import type {RichText, Block} from '@notionhq/client/build/src/api-types';
