How can I handle retrying fetch requests in my application?

You can implement retry logic by using a loop or a library like axios with interceptors. Would you like a code example?

Yes, please provide a code example for retrying fetch requests.

Here's a simple example using fetch:

async function fetchWithRetry(url, options, retries = 3) {
    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) throw error; // Rethrow if it's the last attempt
        }
    }
}

This function will attempt to fetch the URL up to 3 times before failing.

What if I want to add a delay between retries?

You can use setTimeout to add a delay. Here's an updated version:

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)); // Delay before retrying
            } else {
                throw error; // Rethrow if it's the last attempt
            }
        }
    }
}
