@react-hook/switch v1.3.3
A React hook for controlling a boolean value with toggle, on, and off callbacks. This
is extremely useful for adding controlled/uncontrolled component behavior to components
like <Checkbox/>, <Toggle/>, <Modal/>, etc.
Quick Start
import useSwitch from '@react-hook/switch'
// Basic usage
const Component = (props) => {
  const [value, toggle] = useSwitch(false /*default value*/)
  return (
    <>
      <span>Value: {value}</span>
      {/* toggles the current value to its opposite*/}
      <button onClick={toggle}>Toggle</button>
      {/* toggles the current value to true*/}
      <button onClick={toggle.on}>On</button>
      {/* toggles the current value to false*/}
      <button onClick={toggle.off}>On</button>
    </>
  )
}
// Creating a toggle component with a controlled and uncontrolled
// value pattern
const Toggle = ({value: controlledValue, defaultValue, onChange}) => {
  const [value, toggle] = useSwitch(defaultValue, controlledValue, onChange)
  return (
    <>
      <span>Value: {value}</span>
      <button onClick={toggle}>Toggle</button>
      <button onClick={toggle.on}>On</button>
      <button onClick={toggle.off}>On</button>
    </>
  )
}API
useSwitch(defaultValue?, controlledValue?, onChange?)
function useSwitch(defaultValue?: boolean, controlledValue?: boolean, onChange?: (value: boolean, prevValue: boolean) => any): readonly [boolean, (() => void) & {
    on: () => void;
    off: () => void;
}]Arguments
| Argument | Type | Default | Required? | Description | 
|---|---|---|---|---|
| defaultValue | boolean | false | No | Sets the default value of the switch | 
| controlledValue | boolean | undefined | No | Sets the controlled value of the switch, which will override the defaultValue | 
| onChange | (value: boolean) => any | undefined | No | A callback invoked whenever toggle callbacks that change state are invoked | 
Returns [value: boolean, toggle: Toggle]
| Variable | Type | Description | 
|---|---|---|
| value | boolean | Defines the initial value | 
| toggle | () => void & {on: () => void, off: () => void} | If the value is true, calling this will make it false and vice-versa | 
() => void & {on: () => void, off: () => void}
| Method | Type | Description | 
|---|---|---|
| on | () => void | Switches the value to true | 
| off | () => void | Switches the value to false |
