The Fetch API is a modern JavaScript interface for making HTTP requests and handling responses. It provides a more straightforward and flexible way to interact with APIs compared to the older XMLHttpRequest. The Fetch API is promise-based, making it easier to work with asynchronous operations.
Basic Syntax
The core function of the Fetch API is fetch(), which takes the URL of the resource you want to fetch as its first argument. Optionally, you can include an object as the second argument to specify settings such as the HTTP method, headers, and more.
Here's a simple example of a basic fetch request:
fetch('https://api.example.com/data').then(response => response.json()).then(data => console.log(data)).catch(error => console.error('Error:', error));Copied!âś•CopyIn this example, the fetch() function makes a GET request to the specified URL. The response is then converted to JSON using the json() method, and the data is logged to the console. If an error occurs, it is caught and logged.
