Service that checks current external IP and updates DNS records with Porkbun accordingly.
In order to utilise the Fetch() API that this service uses you will need Node.js 19 or higher installed on your server.
The Porkbun API documentation can be found here.
Run npm install in order to install dotenv.
Copy .env.example to .env and populate with your Porkbun API key and secret key.
In the third environment variable called DOMAINS add a comma separated list of the domains you want to update.
Run node pbDNSUpdater.js
You may want to use a NPM module such as PM2 or Forever to run this service perpetually.
This script will work with some modifications.
Install node-fetch at version 2.
npm install node-fetch@2
Import it into pbDNSUpdater.js by adding the following line to the top of the file:
const fetch = require('node-fetch');
The service will now resolve to using the library.
