How do I use fetch in Node.js?

You can use the 'node-fetch' package to use fetch in Node.js. First, install it using npm: npm install node-fetch.

Can you show me a simple example of fetching data from an API?

Sure! Here's a basic example:

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

fetch('https://api.example.com/data')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('Error:', error));

What if I want to send data with a POST request?

You can send data with a POST request like this:

fetch('https://api.example.com/data', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ key: 'value' })
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));

Is there a way to handle errors more effectively?

Yes! You can check the response status before parsing the JSON:

fetch('https://api.example.com/data')
  .then(response => {
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    return response.json();
  })
  .then(data => console.log(data))
  .catch(error => console.error('Error:', error));
