How to make an HTTP request in Javascript

How do I make an HTTP request in Javascript?

You can make an HTTP request in JavaScript using the built-in XMLHttpRequest object or the newer fetch() function. Here's an example using fetch():

****************************************

1 2 3 4

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

**************************************** 

This code sends a GET request to https://example.com/api/data and logs the JSON response to the console. If an error occurs, it will be logged to the console as well.

If you need to send data along with the request, you can pass an options object to fetch() with a method property set to 'POST' or 'PUT' and a body property containing the data to be sent.

***************************************

const data = { name: 'John', age: 30 };

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

***************************************

This code sends a POST request with the JSON-serialized data object in the request body and sets the 'Content-Type' header to 'application/json'. The response is logged to the console as before.
