Why notion-page-to-html?

It's perfect as content manager system

• This tool can get any public page from Notion and convert it to html. This is perfect for the ones who want to use Notion as CMS. Once it gets page content from Notion, it becomes completely independent (images are converted to base64 so you do not have to call Notion again to get content). You can convert a page and then make it private again.

It's fully customizable

• You can choose how you want to get page content. Do you want title, cover, and icon in html body? You can do that! Do you want they apart of html so you can choose where place it? You have it. Do want html without style? Without Equation and Code Highlighting scripts? Do you want body content only? You have those options too.

Basic Usage

Install it in a NodeJS project using npm

npm install notion-page-to-html

Then, just import it and paste a public Notion page url

const NotionPageToHtml = require('notion-page-to-html');

// using async/await
async function getPage() {
  const { title, icon, cover, html } = await NotionPageToHtml.convert("https://www.notion.so/asnunes/Simple-Page-Text-4d64bbc0634d4758befa85c5a3a6c22f");
  console.log(title, icon, cover, html);
}

getPage();

cover is a base64 string from original page cover image. icon can be an emoji or base64 image based on original page icon. html is a full html document by default. It has style, body, MathJax and PrismJS CDN scripts by default. You can pass some options to handle html content.

NotionPageToHtml.convert(
  'https://www.notion.so/asnunes/Simple-Page-Text-4d64bbc0634d4758befa85c5a3a6c22f',
  options,
);

options is an object with the following keys

Key	Default value	If true
excludeCSS	false	returns html without style tag
excludeMetadata	false	returns html without metatags
excludeScripts	false	returns html without script tags
excludeHeaderFromBody	false	returns html without title, cover and icon inside body
excludeTitleFromHead	false	returns html without title tag in head
bodyContentOnly	false	returns html body tag content only
