Using Notion API to Select All Pages with a Specific Emoji

In this technical blog, we will discuss how to use the Notion API to select all subpages of a Notion page that use a specific emoji icon. We will provide a code example that demonstrates this functionality.

To begin with, you will need to have the Notion API key and the ID of the Notion page you want to work with. Make sure to include these in your code.

const notion = new Client({ auth: process.env.NOTION_API_KEY })
const pageId = process.env.NOTION_PAGE_ID

Next, we will define an asynchronous function called getAllSubpagesOfPage that takes a page object and the notion client as parameters. This function will retrieve all the subpages of the given page.

async function getAllSubpagesOfPage(page, notion) {
  const pages = []
  
  const blocks = await notion.blocks.children.list({
    block_id: page.id,
  })
  
  for (const block of blocks.results) {
    if (block.type === 'child_page') {
      const temp = await notion.pages.retrieve({ page_id: block.id })
      block.icon = temp.icon
      pages.push(block)
    }
  }
  
  return pages
}

In the above code, we use the blocks.children.list method to retrieve all the blocks within the given page. We iterate through these blocks and check if each block is a child page. If it is, we retrieve the page object using the pages.retrieve method and add the icon property to the block.

Finally, we call the getAllSubpagesOfPage function and store the result in the pages variable.

const pages = await getAllSubpagesOfPage(page, notion)

To further filter the pages based on a specific emoji icon, we can use the map method and check the emoji property of the icon object.

pages.map(async (page) => {
  if (page.icon?.emoji === '✅') {
    // Page has the desired emoji icon
    // Perform necessary actions here
  }
})

This code snippet demonstrates how to utilize the map method to iterate through the pages array and check if each page’s icon emoji matches the desired emoji icon.

By following these steps and using the provided code example, you can select all subpages of a Notion page that contain a specific emoji icon using the Notion API.
