How can I implement a fetch error retry mechanism in my code?

You can implement a fetch error retry mechanism by using a loop to attempt the fetch multiple times before failing.

What should I do if the fetch keeps failing after several attempts?

You can add a delay between retries and also handle specific error types to decide whether to retry or not.

Can you show me a code example for that?

Sure! Here's a simple example in JavaScript:

async function fetchWithRetry(url, options, retries = 3, delay = 1000) {
    for (let i = 0; i < retries; i++) {
        try {
            const response = await fetch(url, options);
            if (!response.ok) throw new Error('Network response was not ok');
            return await response.json();
        } catch (error) {
            if (i < retries - 1) {
                await new Promise(res => setTimeout(res, delay));
            } else {
                throw error;
            }
        }
    }
}

This function will retry fetching the URL up to the specified number of retries.
