cloudflare-dynamic-dns2

Overview

cloudflare-dynamic-dns2 is a Node.js module that updates a Cloudflare DNS address record with an IP address. See CHANGES.md for difference from original, and reason for this fork.

Command-line program

Installation of command-line program

npm install -g cloudflare-dynamic-dns2

Usage via cli

Create a /etc/cloudflare/config.json for example like this:

{
  "email": "hugo@josefson.org",
  "key": "17b8137B813b585c",
  "domain": "hugojosefson.com",
  "subdomains": [
    "www",
    "@"
  ]
}

The properties are described for the API below.

Run the built-in command-line tool:

update-cloudflare-dns

If the program exits with exit code 0 and prints nothing, all went well. Otherwise it will print whatever error occurred and exit with a non-zero exit code.

API

Installation for API use

npm install --save cloudflare-dynamic-dns2

Usage via API

The cloudflare-dynamic-dns2 module is a function which takes one argument, an options object, with the following properties:

  • email - the email associated with your Cloudflare account (string, mandatory)
  • key - the API key associated with your Cloudflare account (string, mandatory)
  • domain - the domain corresponding to the DNS address record you wish to change (string, mandatory)
  • subdomain - the subdomain corresponding to the DNS address record you wish to change; "@" to update the apex record (string, mandatory)
  • ip - the new IP address for the address record; if no IP address is specified, the external IP address of the current machine is used (string, optional)

The function returns a Promise which resolves to the actual IP address if the request was successful, or rejects with an Error if it was not.

Example

The following example illustrates the basic usage of cloudflare-dynamic-dns2, updating the A record for boo.example.com:

const cloudflareddns = require('cloudflare-dynamic-dns2');
 
// Use external IP address of current machine
cloudflareddns({
    email: 'jsmith@example.com',
    key: 'abcde12235',
    domain: 'example.com',
    subdomain: 'boo'
}).then(
    ip => console.log(`Updated boo.example.com to ${ip}`),
    reason => console.error(reason)
);
