Query Notion DB with JS

main.js

const { Client } = require("@notionhq/client")

const notion = new Client({
  auth: "<NOTION_SECRET>",
  notionVersion: "2022-02-22"
})

;(async() => {
  const res = await notion.databases.query({
    database_id: "<NOTION_DBID>"
  })

  console.log(JSON.stringify(res))
})()

Note the API version on line 5. Its part of the Options object passed into the constructor when creating a new client.
