useModal

🖼 React hook for Modals

undefined undefined undefined Known Vulnerabilities Known Vulnerabilities

Simple, lightweight hook for Modals/Dialogs.

This hook is also isomorphic, meaning it works with SSR (server side rendering).

Features

  • SSR (server side rendering) support
  • TypeScript support
  • 2 dependencies (use-ssr, react-useportal)
  • Built in state

Examples

Installation

yarn add use-react-modal      or     npm i -S use-react-modal

Usage

Basic Usage

import useModal from 'use-react-modal'

const App = () => {
  const { isOpen, openModal, closeModal, Modal } = useModal()

  return (
    <>
      <button onClick={openModal}>Open Me!</button>
      {isOpen && (
        <Modal>
          <button onClick={closeModal}>close</button>
          Whatever you put here will be centered to the middle of the screen.
        </Modal>
      )
    </>
  )
}

With Provider

import useModal, { Provider } from 'use-react-modal'

const MyComponent = () => {
  const { isOpen, openModal, Modal } = useModal()

  return (
    <>
      <button onClick={openModal}>Open Me!</button>
      {isOpen && (
        <Modal>
          Now, whatever you put here will be centered AND have a backdrop
          with the color specified in the Provider
        </Modal>
      )
    </>
  )
}


const App = () => (
  <Provider background='rgba(0, 0, 0, 0.5)'>
    <MyComponent />
  </Provider>
)

Make sure you are passing the html synthetic event to the openModal and toggleModal . i.e. onClick={e => openModal(e)}

Usage with a ref

If for some reason, you don't want to pass around the event to openModal or toggleModal, you can use a targetRef like this.

import useModal from 'use-react-modal'

const App = () => {
  const { targetRef, openModal, closeModal, isOpen, Modal } = useModal()

  return (
    <>
      {/* see below how I don't have to pass the event if I use the ref */}
      <button ref={targetRef} onClick={() => openModal()}>
        Open Modal
      </button>
      {isOpen && (
        <Modal>
          <p>
            <button onClick={closeModal}>Close me!</button>, hit ESC or
            Cool Modal 😜
          </p>
        </Modal>
      )}
    </>
  )
}

Options

Option Description
background sets the color of the backdrop, if nothing is set, there will be no backdrop
closeOnOutsideClick This will close the modal when not clicking within the modal. Default is true
closeOnEsc This will allow you to hit ESC and it will close the modal. Default is true
bindTo This is the DOM node you want to attach the modal to. By default it attaches to document.body
isOpen This will be the default for the modal being open or closed. Default is false
onOpen This is used to call something when the modal is opened
onClose This is used to call something when the modal is closed
html event handlers (i.e. onClick) These can be used instead of onOpen.

Option Usage

const {
  openModal,
  closeModal,
  toggleModal,
  isOpen,
  Modal,
  // if you don't pass an event to openModal, closeModal, or toggleModal, you will need to
  // put this on the element you want to interact with/click to open the modal
  targetRef,
  // this allows you to interact directly with the backdrop/overlay
  backdropRef,
  // this allows you to interact directly with the modal
  modalRef,
} = useModal({
  // sets the color of the backdrop, if nothing is set, the backdrop will be transparent unless it's set in the Provider
  // setting to `null` removes any background set in the `Provider`
  background: 'rgba(0, 0, 0, 0.5)',
  closeOnOutsideClick: true,
  closeOnEsc: true,
  bindTo, // attach the portal to this node in the DOM
  isOpen: false,
  // `event` has all the fields that a normal `event` would have such as `event.target.value`, etc.
  // with the additional `portal` and `targetEl` added to it as seen in the examples below
  onOpen: (event) => {
    // can access: event.portal, event.targetEl, event.event, event.target, etc.
  },
  // `onClose` will not have an `event` unless you pass an `event` to `closePortal`
  onClose({ targetEl, event, portal }) {},
  // `targetEl` is the element that you either are attaching a `ref` to
  // or that you are putting `openPortal` or `togglePortal` or `closePortal` on

  // in addition, any event handler such as onClick, onMouseOver, etc will be handled the same
  onClick({ targetEl, event, portal }) {}
})

Can also do array destructuring

const [openModal, closeModal, isOpen, Modal, toggleModal, targetRef, portalRef, modalRef] = useModal()

Todos

  • animations 😜
  • React Native support. 1 2 3 4 5 Probably going to have to add a Provider...
  • add correct return types
  • tests (priority)
  • potential syntax ideas
    // then you can change the order of the array destructuring syntax
    <Provider order={['Modal', 'openModal']} />
    
    // CustomModal, CustomCloseButton
    <Provider Modal={CustomModal} CloseButton={CustomClostButton} />
    const { Modal, CloseButton } = useProvider()
    
    // customize the modal animations
    const { Modal } = useModal({
      onOpen({ modal }) {
        modal.current.style.cssText = `
          /* do some animation in */
        `
      },
      onClose({ modal }) {
        modal.current.style.cssText = `
          /* do some animation out */
        `
      }
    })
    
    // customize the modal animations idea 2
    const { Modal } = useModal({
      animateIn: `
        /* css for animating in */
      `,
      animateOut: `
        /* css for animating out */
      `,
    })
    
    // customize the modal animations idea 3
    // maybe have some predefined options?
    const { Modal } = useModal({
      animate: 'fade-in-out', // 'slide-in-top', etc...
    })
