Hint: If a record is not existing, CDS will automatically create it when syncing.

Javascript Example

const Cddnss = require('cloudflare-ddns-sync').default;

const cddnss = new Cddnss('your@email.com', '<your-cloudflare-api-key>');

const records = [
  {
    name: 'test-1.domain.com',
    type: 'A',          // optional
    proxied: true,      // optional
    ttl: 1,             // optional
    priority: 0,        // optional
    content: '1.2.3.4', // optional
  },
  {
    name: "test-2.domain.com"
  }
];

cddnss.syncRecords(records).then((result) => {
  console.log(result);
});

Typescript Example

import Cddnss, {Record, RecordData} from 'cloudflare-ddns-sync';

const cddnss: Cddnss = new Cddnss('your@email.com', '<your-cloudflare-api-key>');

const records: Array<Record> = [
  {
    name: 'test-1.yourdomain.com',
    type: 'A',          // optional
    proxied: true,      // optional
    ttl: 1,             // optional
    priority: 0,        // optional
    content: '1.2.3.4', // optional
  },
  {
    name: "test-2.yourdomain.com"
  },
];

cddnss.syncRecords(records).then((result: Array<RecordData>) => {
  console.log(result);
});
