No-cache policy with Vercel's SWR

no-cache-swr.js

import useNativeSWR from 'swr'
import { useRef } from 'react'

// inspired by https://github.com/vercel/swr/discussions/456
export default function useSWR(key, fetcher, options = {}) {
  const { cachePolicy, ...opts } = options
  const random = useRef(new Date())

  return useNativeSWR(
    () => {
      const shouldAvoidCache = cachePolicy === 'no-cache'
      if (!shouldAvoidCache) {
        return typeof key === 'function' ? key() : key
      }
      let finalKey = key
      if (typeof key === 'function') finalKey = key()
      if (!Array.isArray(finalKey)) finalKey = [finalKey]

      return [...finalKey, random]
    },
    fetcher,
    opts
  )
}

// usage:
const fetcher = () => getUsers()
const { data } = useSWR('users', fetcher, { cachePolicy: 'no-cache' })
