This is a tiny script for my use that migrates all my Gandi domains to use Cloudflare DNS.

To install dependencies, ensure you have the latest version of bun installed, and then run:

bun install

Create a file called .env with your Gandi API token and a Cloudflare token with the following permissions:

• User > Memberships > Edit
• Zone > Zone Settings > Edit
• Zone > Zone > Edit

Then simply run:

bun run index.ts

This script is idempotent; it's safe to run more than once as it will skip domains that already have their nameservers updated to CF.
