Highlights of This Release

shouldRetryOnError accepts a function

Previously shouldRetryOnError is either true or false. Now it accepts a function that conditionally determines if SWR should retry. Here's a simple example:

const fetcher = url => fetch(url).then(res => {
  // Fetcher throws if the response code is not 2xx.
  if (!res.ok) throw res
  return res.json()
})

useSWR(key, fetcher, {
  shouldRetryOnError: (error) => {
    // We skip retrying if the API is returning 404:
    if (error.status === 404) return false
    return true
  }
})
