useUpdateEffect

useEffect that skips the initial mount and runs only on subsequent dependency changes.

Usage#

import { useUpdateEffect } from '@primereact/hooks/use-update-effect';

useUpdateEffect(() => {
    onValueChange(value);
}, [value]);

The effect does not run on the first render. Every time one of the dependencies changes afterwards, it fires like a normal useEffect.

Signature#

function useUpdateEffect(effect: React.EffectCallback, deps?: React.DependencyList): void;

When to use it#

Triggering side effects that only make sense after a user-driven change — firing a controlled onChange, syncing to a remote store, or announcing transitions.
