How to revalidate manually and trigger data update immediately?

[TROJAN]

I'm using swrv in Vue3 + Pinia project.

In the Pinia store there's the following code:

export const useClusterStore = defineStore('cluster', () => {
  const clusters = ref()

  // Omit fetcher to use the default Fetch API
  const { data, mutate: getClusterList } = useSWRV(`${baseUrl}/cnpgs`), {
    refreshInterval: 30000,
  })
  watch(data, (newVal) => {
    clusters.value = newVal?.items
  }, { deep: true })

  return {
    clusters,
    getClusterList,
  }
})

Now, I want to revalidate manually at some time, eg. every time the clusters page show (after cluster created and navigate to this page), so there's the following code in .vue file:

<script lang="ts" setup>
const clusterStore = useClusterStore()

onMounted(() => {
  clusterStore.getClusterList()
})
</script>

But this didn't trigger revalidate and "watch" observer, also the clusters data is the old, not the latest.

Is there some logic error of my code or bug? What's the right way to revalidate manually and refresh data immediately? Thanks guys.

You could also add a dynamic key (a ref) in your swrv key that can be mutated.

export const useClusterStore = defineStore('cluster', () => {
  const clusters = ref()
  const cacheKey = ref(0)

  // Omit fetcher to use the default Fetch API
  const { data, mutate: getClusterList } = useSWRV(
    () => cacheKey.value && '/cnpgs',
    () => fetch(`${baseUrl}/cnpgs`), 
    { refreshInterval: 30000 }
  )

  watch(data, (newVal) => {
    clusters.value = newVal?.items
  }, { deep: true })

  return {
    clusters,
    getClusterList,
    cacheKey,
  }
})

<script lang="ts" setup>
const { cacheKey } = storeToRefs(useClusterStore())

onMounted(() => {
  cacheKey.value++
})
</script>

@adamdehaven Thanks for your replay, but it still not work. cacheKey actually increased, but didn't revalidate immediately.

And there's a TS error when set () => cacheKey.value && '/cnpgs': The type '() => string | 0' cannot be assigned to the type 'IKey'. Also when I use () => Boolean(cacheKey.value) && '/cnpgs'.
