This is a very simple tool to export a workspace from Notion, designed to work as part of a GitHub workflow.

It reads NOTION_TOKEN and NOTION_SPACE_ID from the environment, and outputs the export to both html and markdown directories in the current working directory, as well as to html.zip and markdown.zip.

NOTE: if you log out of your account, the NOTION_TOKEN will get invalidated and this process will fail. There isn't anything that I know of that I can do about that until Notion decide to add a backup endpoint to their official API, at which point this will be able to use a proper authentication token.

This assumes you are looking to set this up to back up Notion to GitHub.

1. Create a repo for your backup. You probably want it private.
2. Get the NOTION_TOKEN and NOTION_SPACE_ID as explained in this blog post.
3. Set them as secrets in your GitHub repo.
4. Install the following under .github/workflows/whatever.yml in your repo.

  push:
    branches:
      - main
  # schedule:
  #   -   cron: "*/5 * * * *"
