Question 1

How to use throttle-debounce with React hooks?

Accepted Answer

Import throttle or debounce and use them inside useEffect or custom hooks. For example, wrap a state update function with debounce to limit API calls on input changes, and remember to cancel in the cleanup function to prevent memory leaks.

Question 2

throttle-debounce vs Lodash debounce: which should I use?

Accepted Answer

throttle-debounce is lighter and dependency-free, ideal if you only need throttle/debounce. Lodash's debounce is part of a larger library, so if you're already using Lodash for other utilities, stick with it to avoid extra dependencies.

Question 3

Can I cancel a pending debounced call in throttle-debounce?

Accepted Answer

Yes, call the cancel method on the returned function. Use debounceFunc.cancel() to stop all pending executions, or pass upcomingOnly: true to cancel only the next call, as shown in the README examples.

Question 4

What's the difference between throttle and debounce in this library?

Accepted Answer

Throttle limits calls to at most once per delay period, while debounce delays execution until after a quiet period. The library adds options like atBegin for debounce to trigger at the start or end, making it versatile for different use cases.

Question 5

Does throttle-debounce work in Node.js?

Accepted Answer

Yes, it's a plain JavaScript utility without browser-specific code, so you can use it in Node.js for rate-limiting async operations. However, the README focuses on browser events, so test it in your Node environment.

Question 6

How to set throttle to only run at the end of the delay?

Accepted Answer

Configure throttle with noLeading: true and noTrailing: false. This skips the immediate execution on the first call and ensures the callback runs after the delay when calls stop, as explained in the API options.
