use-effect-once-when v1.0.1

use-effect-once-when

React useEffect() that waits for a condition to be met, then runs only once.

Installation

Install use-effect-once-when locally within your project folder, like so:

npm install use-effect-once-when

Or with yarn:

yarn add use-effect-once-when

Basic Usage

You can use this hook as an alternative to useEffect() when you want the effect to be run only once.

useEffectOnceWhen() will wait for a condition to be met, and then will run the effect only once. useEffectOnce() will run once on first render only without waiting for any condition to be met.

Typescript

    },
    []);

Javascript

        // Do something with data
