Question 1

How does p-memoize handle caching for multiple arguments or objects?

Accepted Answer

By default, p-memoize only uses the first argument for caching, but you can configure it with a custom cacheKey function, such as JSON.stringify, to handle multiple arguments or objects by value, as described in the caching strategy section.

Question 2

Does p-memoize cache rejected promises or errors?

Accepted Answer

No, p-memoize specifically avoids caching rejected promises to prevent error propagation; it only caches resolved values, making it safer for async workflows where failures shouldn't be stored.

Question 3

p-memoize vs memoize: which one should I use?

Accepted Answer

Use p-memoize for promise-returning or async functions, as it handles async caching and error avoidance, while memoize is better for synchronous functions. p-memoize is explicitly designed as an async-enhanced version, as mentioned in the README.

Question 4

How to implement LRU cache with p-memoize?

Accepted Answer

You can integrate p-memoize with LRU cache libraries like quick-lru by passing the cache instance in the options, allowing automatic eviction of least recently used items to manage memory efficiently, as shown in the API examples.

Question 5

Can I use p-memoize in browser environments?

Accepted Answer

Yes, p-memoize works in both Node.js and browser environments since it relies on standard JavaScript features like Promises and Maps, but ensure polyfills for older browsers if needed, as it doesn't specify browser compatibility.

Question 6

How to clear the cache for a memoized function?

Accepted Answer

Use the pMemoizeClear utility function provided by the library to clear all cached data for a memoized function, which throws an error if applied to non-memoized functions, as detailed in the API section.
