This repo provides the foundation for any Notion API project that uses the JavaScript SDK.
This repo uses an express server for its back-end and you can change its specs on server.js but you should be ready to work with your data right off the bat!
If you would like to run this project, you'll need to create a .env file in the root directory and inside it you should add your NotionAPI key and your Database ID like so
NOTION_API_KEY = [Here you should insert your key]
NOTION_API_DATABASE = [Here you should insert your key]
If you don't know how to get your key, go to developers.notion.com, press My Integrations, choose New Integration and once you fill all the info, you should get a Internal Integration Token.
If you don't know how to get your Database id, check the Where can I find my database's ID? of this NotionAPI doc
