How does the AbortController work with async/await in JavaScript?

Can you explain how the AbortController works with async/await in JavaScript?

Sure! The AbortController is used to abort ongoing asynchronous operations, like fetch requests. When you create an instance of AbortController, it provides an abort signal that can be passed to the async function.

How do I implement it in a fetch request?

You can implement it by creating an instance of AbortController, then passing its signal to the fetch request. If you need to abort the request, you call the abort method on the controller.

Can you show me a code example?

Absolutely! Here's a simple example:

const controller = new AbortController();
const signal = controller.signal;

async function fetchData() {
    try {
        const response = await fetch('https://api.example.com/data', { signal });
        const data = await response.json();
        console.log(data);
    } catch (error) {
        if (error.name === 'AbortError') {
            console.log('Fetch aborted');
        } else {
            console.error('Fetch error:', error);
        }
    }
}

// To abort the fetch request:
controller.abort();

What happens if I abort the request?

If you abort the request, the fetch promise will reject with an AbortError, allowing you to handle it gracefully in your code.
