A type-safe and powerful Notion client.

🚀 Get started • 🔧 Configure • 🔍 Query • 🏗 Extend

⚠ Pre-release

This project is currently in pre-release, you can use it but some features are lacking and few things will have to change in a near future.

Do not hesitate to open an issue to provide your feedback, report bugs and to propose new features.

🚀 Getting started

Install libraries

$ npm install @notionx/client @notionx/renderer
$ yarn add @notionx/client @notionx/renderer

⚠ We highly recommend to use a Static Website Generator to use @notionx/client. The Notion API is extremely slow, avoid querying it on each visit.

Create a database

Query your database

import { Client, DatabaseSchema } from '@notionx/client';

const client = new Client({
  auth: process.env.NOTION_TOKEN,
});

const schema: DatabaseSchema = {
  slug: {
    name: 'Slug',
    type: 'right_text',
  },
  status: {
    name: 'Status',
    type: 'select',
  },
};

// Query a database
const pages = await client.queryDatabase(
  '<databaseId>',
  schema
  {
    filter: [
      {
        status: {
          equals: 'Published',
        },
      },
    ],
    sorts: {
      slug: 'ascending',
    },
  }
);

const page = await client.page(schema, '<pageId');

// Render your page content
const html = await page.html()

Get a Notion Token

To interact with Notion you need to create an integration and give it the correct permissions.

Create a new integration by heading to the following link.

You should then be able to get an Internal Integration Token.

⚠️ Make sure that you are giving the correct permissions. If the token is directly accessible from your Frontend it can be a real problem!

Add the integration to your databases

On each databases you want to query click on the ••• in the top right corner.

Click on Add connection and select your Integration. Your token should now have access to your database.

🔧 Configure

`NotionCMS`

NotionCMS is used to interact with a Notion Account.

import { Client } from '@notionx/client';

const cms = new Client({
  auth: '<your-authentication-token>', // Your Notion Internal Integration Token
  renderer: notionRenderer, // A NotionRenderer instance
  parser: notionParser, // A NotionParser instance
});

`NotionDatabase`

The NotionDatabase is used to interact with a specific Notion database.

import { NotionDatabse } from '@notionx/client';

const database = new NotionDatabase({
  cms: notionCMS, // Your NotionCMS instance
  databaseId: '<my-database-id>', // The ID of the Notion Database
  mapping: {
    title: {
      // The property key of the final object
      name: 'Title', // The name of the page Property
      id: 'title', // The id of the page Property
    },
    shortDescription: {
      name: 'Short description',
    },
  },
});

The mapping is optionnal, if you do not specify it, the keys will be taken from the properties name.

`NotionRenderer`

The NotionRenderer instance is used to transform properties and content into HTML. It accepts custom Blocks.

🔍 Query

List pages of a database

import { NotionDatabase } from '@notionx/client';

const database = new NotionDatabse({ ... })

const posts = await database.list()

const posts = await database.list({
    // Filtering
    filter: {
        property: 'Status', // The property name
        type: 'status', // The property type
        status: {
            equals: 'Published' // What status you want to query
        }
    },

    // Pagination
    pageSize: 2, // The number of pages to query
    cursor: '<cursor>', // At what page the list starts

    // Sorting [WIP]
})

Query a single page by ID

import { NotionDatabase } from '@notionx/client';

const database = new NotionDatabse({ ... })

const post = await database.get('<page-id>');

Query a single page by property

import { NotionDatabase } from '@notionx/client';

const database = new NotionDatabse({ ... })

const post = await database.findFirst({
    property: 'Slug',
    rich_text: {
        equals: 'my-super-post'
    }
})

Get the content of a page

When querying pages, you will only get the properties. You must query the content with the getContent method.

The content is automatically rendered into HTML.

import { NotionDatabase } from '@notionx/client';

const database = new NotionDatabse({ ... })

const post = await database.findFirst({
    property: 'Slug',
    rich_text: {
        equals: 'my-super-post'
    }
})

const content = await database.getContent(post.id);

🏗 Extend

Parsers

Parsers transform page properties sent by the Notion API.

For example, a date property in Notion results in a string but we parse it to transform it into a Date and make it directly accessible into the final object.

In the following examples we replace the first part of each email with fake data.

import { faker } from '@faker-js/faker';
import { NotionParser, NotionCMS, PropertyParser } from '@notionx/client';

const fakeEmailParser: PropertyParser<string, string> = (data) => {
  const domain = data.email.split('@').at(-1);
  return `${faker.internet.userName()}@${domain}`;
};

// Add it through the constructor
const parser = new NotionParser({
  propertyParsers: {
    email: fakeEmailParser,
  },
});

// Or with the method addParser
parser.addParser('email', fakeEmailParser);

// Use it in NotionCMS
const cms = new NotionCMS({ parser });

Renderers

Notion does not transform the rich content into HTML. It returns a JSON object with the configuration of each block.

You can add custom renderer to override the current Renderers or to handle more blocks.

import { createBlockRenderer, NotionRenderer } from '@syneki/notion-renderer';

const customParagraphRenderer = createBlockRenderer(
  'paragraph',
  (data, renderer) => {
    return `<p class="custom-paragraph">${renderer.render(
      ...data.paragraph.rich_text
    )}</p>`;
  }
);

// Add it through the constructor
const renderer = new NotionRenderer(customParagraphRenderer);
// Or with the method addBlockRenderer
renderer.addBlockRenderer(customParagraphRenderer);

// Use it in NotionCMS
const cms = new NotionCMS({ renderer });

As you can see we can render Blocks into blocks. In this case a Code Block contains Rich text, we call the renderer.render method to render it with the RichTextRenderer.
