Attempt re-fecth on network error

When API call fails due to network error this is how to wait 1 second and try again once more before calling it quits.

// Thin wrapper around native fetch that allows
// passing arbitrary number of retries.
const fetchWithRetry = (url, options, retry = 1) => {
    return fetch(url, options)
    .then((resp) => resp.json())
    .catch((error) => {
        // fetch throws TypeError for network errors.
        // Need to handle other API error is some other way.
        if (error instanceof TypeError) {
            // In case of NETWORK_ERROR wait for 1s and try re-fetch once.
            return new Promise((resolve) => setTimeout(resolve, 1000))
            .then(() => fetchWithRetry(url, options, retry - 1))
            .catch((error) => {
                throw error;
            });
        }
    });
