Specifies caching behavior for the loader and its dependencies.

• no-store:

  • Completely bypasses the cache, ensuring that the loader always runs and fetches fresh data.
  • This setting also changes ctx.vary.shouldCache to false, which prevents other dependent sections from being cached.
  • The vary is not set, even if the loader has a cache key.

• no-cache:

  • Ignores the cache for the current loader run, but does not affect the caching behavior of other dependent blocks.
  • This is useful for loaders that should always execute but whose results can still be cached.

• stale-while-revalidate:

  • If no data exists for a cache key, the loader runs, and the fresh data is returned.
  • If stale data is available, it is returned immediately while the loader runs in the background to revalidate and update the cache if the data is outdated.
