Welcome to nodedig

nodedig is a powerful Node.js library designed for developers to interact with DNS and network services seamlessly. In this guide, we dive deep into the most useful APIs that nodedig offers, along with practical code snippets to help you understand how to use them effectively.

Getting Started with nodedig

First, you need to install nodedig into your project:

  
  npm install nodedig
  

APIs Overview

Let’s explore some of the most useful nodedig APIs:

1. DNS Lookup (A Record)

This API allows you to fetch the A Record for a given domain:

  
  const nodedig = require('nodedig');

  nodedig.lookup('example.com', 'A')
    .then(response => {
      console.log(response);
    })
    .catch(error => {
      console.error(error);
    });
  

2. DNS Lookup (MX Record)

Fetch the MX Records for a domain, commonly used to retrieve email server information:

  
  nodedig.lookup('example.com', 'MX')
    .then(response => {
      console.log(response);
    })
    .catch(error => {
      console.error(error);
    });
  

3. Reverse DNS Lookup

This API enables you to perform a reverse DNS lookup:

  
  nodedig.reverse('8.8.8.8')
    .then(response => {
      console.log(response);
    })
    .catch(error => {
      console.error(error);
    });
  

4. DNS Lookup (TXT Record)

Retrieve the TXT Records for specified domains:

  
  nodedig.lookup('example.com', 'TXT')
    .then(response => {
      console.log(response);
    })
    .catch(error => {
      console.error(error);
    });
  

Putting It All Together: Building an Application

Let’s create a simple application that utilizes the nodedig APIs:

  
  const nodedig = require('nodedig');

  const domains = ['example.com', 'google.com'];

  domains.forEach(domain => {
    nodedig.lookup(domain, 'A')
      .then(response => {
        console.log(`A Records for ${domain}: `, response);
      })
      .catch(error => {
        console.error(error);
      });

    nodedig.lookup(domain, 'MX')
      .then(response => {
        console.log(`MX Records for ${domain}: `, response);
      })
      .catch(error => {
        console.error(error);
      });
  });
  

This code will output the A and MX records for each domain in our list, making it simple to gather essential DNS information.
