withCache<TData>(fn, __namedParameters): Promise<TData>

Defined in: utils/cache/withCache.ts:61

Returns the result of a given promise, and caches the result for subsequent invocations against a provided cache key.

Also deduplicates concurrent calls — if multiple callers request the same cache key while the promise is pending, they share the same promise.
