type alias MemoizeOptions
Unstable

Options for memoize.

Type Parameters

Fn extends (...args: never[]) => unknown

The type of the function to memoize.

Key

The type of the cache key.

Cache extends MemoizationCache<Key, MemoizationCacheResult<ReturnType<Fn>>>

The type of the cache.

Properties

optional
cache: Cache

Provide a custom cache for getting previous results. By default, a new Map object is instantiated upon memoization and used as a cache, with no limit on the number of results to be cached.

Alternatively, you can supply a LruCache with a specified max size to limit memory usage.

optional
getKey: (
this: ThisParameterType<Fn>,
...args: Parameters<Fn>,
) => Key

Function to get a unique cache key from the function's arguments. By default, a composite key is created from all the arguments plus the this value, using reference equality to check for equivalence.

optional
errorIsCacheable: (err: unknown) => boolean = () => false

Callback to determine if an error or other thrown value is cacheable.
