Question 1

How do I debounce an async API call in JavaScript?

Accepted Answer

Wrap your async function with p-debounce, specifying the wait time in milliseconds. For instance, for a search input, use pDebounce(fetchData, 300) to delay calls until after user typing pauses, preventing excessive requests.

Question 2

p-debounce vs lodash debounce: which is better for promises?

Accepted Answer

p-debounce is purpose-built for promises with features like promise deduplication and abort signals, making it more robust for async workflows. Lodash debounce is general-purpose but requires manual promise handling and lacks native async optimizations.

Question 3

Can I cancel a debounced function with p-debounce?

Accepted Answer

Yes, use the 'signal' option with an AbortSignal to cancel pending executions. This is useful for scenarios like component unmounting in React or aborting outdated user requests.

Question 4

What's the difference between p-debounce and p-throttle?

Accepted Answer

p-debounce delays execution until after a wait time since the last call, ideal for events like typing. p-throttle limits execution to once per specified interval, better for continuous events like scrolling. Choose based on whether you need delay-based or rate-based control.

Question 5

How to use p-debounce with React hooks?

Accepted Answer

Import p-debounce and use it inside useEffect or useCallback. For example, wrap an async handler with pDebounce and cleanup with abort signals to prevent memory leaks on component updates.

Question 6

Does p-debounce work in Node.js?

Accepted Answer

Yes, it's compatible with both Node.js and browser environments, as shown in the install and usage examples. It relies on standard JavaScript features, making it versatile for server-side or client-side async operations.
