useIsOpen

useIsOpen is a react hook for managing open and close states, designed to simplify the management of open/close states

Installation

Install the package using npm:

npm install useisopen

Or with yarn:

yarn add useisopen

Usage:

import useIsOpen from 'use-is-open'

function App() {
  const [isOpen, { open, manualClose }] = useIsOpen({
    open(e) {
      log(e)
    },
    manualClose([state, setState, reset], anchor) {
      log(anchor)
      setState(null)
    },
  })

  return (
    <React.Fragment>
      <Button onClick={open}>Open Modal</Button>
      <Modal open={isOpen} onClose={manualClose} />
    </React.Fragment>
  )
}

Configuration Options

• initialState (optional): The initial state of your component (default: false).
• openIndicator (optional): Indicator for the open state (default: true).
• closeIndicator (optional): Indicator for the close state (default: false).
• open (optional): Custom logic to execute when opening.
• close (optional): Custom logic to execute when closing.
• manualOpen (optional): Custom logic for manual opening, you have to set the open state yourself.
• manualClose (optional): Custom logic for manual closing, you have to set the close state yourself.

When useIsOpen is called, it will return an array of two members, the first member is the current opening state, initially, it's defined in your configuration object (which you can provide to useIsOpen(config)), it's the initialState property. by default the initialState is config.closeIndicator, which is false. you can tweak that of course, using the config object as well.

the second member in the returned array is an object holding four methods, open, close, manualOpen, manualClose.

open and close, you can invoke them when you want to open/close something. Both methods can be called with one argument. these arguments can be used within your config object as parameters. You can have any argument you want.

In case you wanted to pass multiple arguments, you pass them as one argument in an array or object. for example:

open([a, b, c])

you can then use a, b and c as follows in the config object as follows:

const [isOpen, { open, manualClose }] = useIsOpen({
  open(args) {
    args[0] // the variable a
    args[1] // the variable b
    args[2] // the variable c
  },
})

When the function open is invoked, the state is changed to indicate that the modal, menu, or whatever you're working on is now opened.

close is to set the state to close that thing.

in case you want to have more control, use the manualOpen and manualClose methods instead.

They give you the freedom to set the state yourself, so you can for example set the state as follows:

const [isOpen, { open, manualClose }] = useIsOpen({
  manualOpen(stateToolkit, args) {
    const [state, setState, reset] = stateToolkit
    setState((previousState) => !previousState) // a react thing, nothing fancy. useful for setting the state synchronously
  },
})

manualOpen and manualClose gets called with two arguments, the stateToolkit argument, which is an array holding three members, [state, setState, reset].

• state and setState are obvious, they're the react useState() returned values.
• reset is a method to set the state (setState) back to the initialState.

The second argument manualOpen and manualClose gets called with is the argument you provide when you call these methods.
