How to Make an HTTP Request with JavaScript

JavaScript uses the Fetch API for HTTP requests. It's built into modern browsers and Node.js (18+), and returns Promises.

GET request example

Making a GET request to fetch data with custom headers:

const response = await fetch("https://api.example.com/users", {
  method: "GET",
  headers: {
    "Accept": "application/json",
    "Authorization": "Bearer YOUR_TOKEN"
  }
});
const data = await response.json();

POST request example

Making a POST request to send JSON data:

const response = await fetch("https://api.example.com/users", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ name: "John", email: "john@example.com" })
});
const data = await response.json();
