useToggle
A hook to toggle a boolean value with useToggle.
Install:
npm i @uidotdev/usehooks
Description:
Basically, what this hook does is that, it takes a parameter with value true or false and toggles that value to opposite. It’s useful when we want to take some action into its opposite action, for example: show and hide modal, show more/show less text, open/close side menu.
Parameters
| Name | Type | Description |
|---|---|---|
| initialValue | boolean | (Optional) The initial value of the toggle state. |
Return Value
The useToggle hook returns an array with the following elements:
| Index | Type | Description |
|---|---|---|
| 0 | boolean | The current state of the toggle. |
| 1 | function | A function to toggle the state of the toggle. |
Demo:
Example:
import * as React from "react";
import { useToggle } from "@uidotdev/usehooks";
function ToggleDemo({ on, toggle }) {
return (
<div>
<label className="toggle">
<input
onChange={toggle}
className="toggle-checkbox"
type="checkbox"
checked={on}
/>
<div className="toggle-switch"></div>
<span className="toggle-label">{on ? "On" : "Off"}</span>
</label>
</div>
);
}
export default function App() {
const [on, toggle] = useToggle(true);
return (
<section>
<h1>UseToggle</h1>
<button disabled={on} className="link" onClick={() => toggle(true)}>
Turn On
</button>
<button disabled={!on} className="link" onClick={() => toggle(false)}>
