do-dns-update

Update a dns record through the DigitalOcean API.

Personally im using it to make sure that my gaming server that is sitting behind a dynamic IP got a working subdomain pointing to it :)

Installation

npm install do-dns-update

Example code

As simple as it gets, you won't really know if the change went through or not. Check out the return object below the example code.

const api_key = 'bd17aec......ec8'; // API key from Digital Ocean (https://cloud.digitalocean.com/account/api/)
const Updater = require('do-dns-update');

(async () => {

    try {
        const updater = new Updater(api_key);
        await updater.setIP('game', 'example.com'); //Sets the ip of game.example.com to your currently external resolved IP.

    } catch (error) {
        console.log(error);
    }

})();

setIP() returns an object that you can access to figure out if the change went through or not.

{
  success: true/false
  subdomain: affected subdomain with domain.
  ip: the ip that got set
  message: short message, could be that an update was done, failed or didnt run because it is already pointing to the same ip.
}
