Fetch Api Development Tutorials, Guides & Insights

JavaScript isn't limited to the browser anymore. It's being used in diverse domains:

• Tools like React Native enable building native apps using JavaScript.
• Example: Facebook's mobile app.

• The form is submitted without a page reload by preventing the default form submission behavior.
• We send a POST request to the API using fetch(), including the form data as JSON in the request body.
• The server's response is displayed on the page.

When working with AJAX, it’s important to handle errors properly. Both XMLHttpRequest and Fetch API provide mechanisms to catch and handle errors.

• Custom Headers: Extend the hook to accept custom headers or authentication tokens in the options parameter.
• Polling: Implement a polling mechanism by setting up a setInterval within the useEffect for periodically fetching data.
• Data Transformation: Add a callback function to transform the fetched data before setting it in state.
