The best way to fetch data from external APIs in Node.js is to use a dedicated HTTP client library such as Axios or Node-Fetch. These libraries provide a simple and easy-to-use interface for making HTTP requests and parsing the responses.

Here is an example of how to fetch data from an external API using Axios:

const axios = require('axios');

const API_URL = 'https://api.example.com/users';

axios.get(API_URL)
  .then(response => {
    const users = response.data;

    // Do something with the users data
  })
  .catch(error => {
    // Handle the error
  });

Node-Fetch is another popular HTTP client library for Node.js. It has a similar API to Axios, but it is slightly more lightweight and efficient.

Here is an example of how to fetch data from an external API using Node-Fetch:

const fetch = require('node-fetch');

const API_URL = 'https://api.example.com/users';

fetch(API_URL)
  .then(response => response.json())
  .then(users => {
    // Do something with the users data
  })
  .catch(error => {
    // Handle the error
  });

Which HTTP client library you choose is a matter of personal preference. However, I recommend using Axios or Node-Fetch, as they are both popular and well-maintained libraries.
