Making HTTP GET requests

This code sample demonstrates how to make a simple HTTP GET request to retrieve data from a specified URL and then process the JSON response.

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

Making HTTP POST requests

This code sample shows how to make an HTTP POST request to send JSON data to a server and then handle the JSON response.

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));

Handling HTTP errors

This code sample illustrates how to handle errors in HTTP requests by checking the response status and throwing an error if the response is not successful.

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));
