Cloudflare Account

Installation

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

Javascript Example

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

// either email and key or token
const cddnss = new Cddnss({
  email: 'your@email.com',
  key: '<your-cloudflare-api-key>',
  token: '<your-cloudflare-api-token>',
});

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';

// either email and key or token
const cddnss = new Cddnss({
  email: 'your@email.com',
  key: '<your-cloudflare-api-key>',
  token: '<your-cloudflare-api-token>',
});

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);
});
