Today I am going to discuss about the Fetch API which is the most powerful and modern way to handle HTML requests.
The Fetch API is a built-in JavaScript interface that allows you to make network requests similar to XMLHttpRequest, but with a cleaner, promise-based syntax. It’s widely used for fetching resources like JSON data from APIs, submitting form data, or uploading files.
It is mainly used because:
- Replaces the more complex XML requests.
- Uses Promises to make async operations which is more effective. 3.Works in both browser and worker contexts.
Syntax:
fetch(url, options)
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));
The most common HTTP methods are
GET Retrieve data
POST Add new data to server
PUT Update existing data
DELETE Remove existing data from server
Fetch supports Cross-Origin Resource Sharing (CORS), allowing requests to external domains if the server permits it.
That's all about the Fetch API....see you all in the next post.
