How do I use fetch with retry in React Native?

You can use the fetch API along with a retry mechanism. One common approach is to create a function that wraps the fetch call and retries it a specified number of times on failure.

Can you show me an example of that?

Sure! Here's a simple example:

const fetchWithRetry = async (url, options = {}, retries = 3) => {
    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 (retries > 0) {
            return fetchWithRetry(url, options, retries - 1);
        }
        throw error;
    }
};

This function will attempt to fetch the URL and retry if it fails.

What options can I pass to the fetch function?

You can pass options like method (GET, POST), headers, body, and more. For example:

const options = {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
    },
    body: JSON.stringify(data),
};
