Development Tool

Notion

Overview

Notion is an all-in-one workspace. It integrates document creation, databases, and project management to streamline team collaboration.

Details

Notion was founded in 2016 by Ivan Zhao and Simon Last, achieving rapid growth through an innovative approach that integrates traditionally dispersed tool groups into a single platform. The block-based editor allows free combination of text, images, videos, databases, and embedded content to create documents. Database functionality enables structured management of relational data, displayable in various views including calendar, board, list, and gallery formats. Template functionality maintains consistent document formatting, while task management and project tracking can be performed in an integrated manner. Real-time collaboration features enable simultaneous editing with team members, with detailed comment and permission management settings. Since 2023, AI functionality has been integrated, providing document creation automation, summarization, translation, and other support features. For developers, this is a highly versatile tool applicable to a wide range of uses including technical documentation, API specifications, project planning, and knowledge bases.

Automation Using API

// Notion API example (Node.js)
const { Client } = require('@notionhq/client');

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

// Creating a page
async function createPage() {
  const response = await notion.pages.create({
    parent: {
      database_id: 'database_id_here',
    },
    properties: {
      'Task Name': {
        title: [
          {
            text: {
              content: 'New Task',
            },
          },
        ],
      },
      'Status': {
        select: {
          name: 'In Progress',
        },
      },
      'Due Date': {
        date: {
          start: '2025-07-01',
        },
      },
    },
  });
  
  return response;
}

// Querying database
async function queryDatabase() {
  const response = await notion.databases.query({
    database_id: 'database_id_here',
    filter: {
      property: 'Status',
      select: {
        equals: 'In Progress',
      },
    },
    sorts: [
      {
        property: 'Due Date',
        direction: 'ascending',
      },
    ],
  });
  
  return response.results;
}
