Use-modal-transition NPM

useModalTransition hook

This is a react hook for adding transition between an element on your page and an element in modal.

Features

Based on the “flip animation technique”,
Support react and nextjs,
It's a hook, so there's no problem with the container ruining your style
Use the Web Animations API (WAAPI),
Lightweight,
Wait until image in modal is loaded,
Images in Modal height and width property can be set to “auto” (when “imgLoaded” added),
Works with “srcset” and "sizes" (when “imgLoaded” added),
Many configuration options,
Tested in Cypress

Setup

To run this project, install it locally using npm:

npm i use-modal-transition

Quick start

1) Import the “useModalTransition” hook:

import useModalTransition from "use-modal-transition";

2) Assign refs to the elements you want to animate.

const firstElemRef = useRef<HTMLDivElement>(null);
const modalElemRef = useRef<HTMLDivElement>(null);

<Modal isOpen={isOpen} onClose={onClose}>
   <div ref={modalElemRef}></div>
</Modal>

<div ref={firstElemRef}></div>

3) Create a state for the modal

const [isOpen, setIsOpen] = useState(false);

4) Call the hook and pass the references and modal state

 useModalTransition({
    modalOpened: isOpen,
    firstElemRef,
    modalElemRef,
  });

5) Change the state onClick to start the animation.

 return (
    <>
    <Modal isOpen={isOpen} onClose={onClose}>
        <div
          onClick={() => {
            setIsOpen(false);
          }}
          ref={modalElemRef}>
        </div>
     </Modal>
      
     <div
       ref={firstElemRef}
       onClick={() => {
       setIsOpen(true);
       }}>
     </div>
 
    </>
  );

Usage details

Property	Default	Type	Details
modalOpened	-	boolean	Changing this to „true” starts opening the animation, changing to “false” starts closing the animation.
firstElemRef(ref)	-	React.RefObject	Reference to an element on the page, needed to download the dimensions for the animation.
modalElemRef(ref)	-	React.RefObject	Reference to an element in the modal, needed to download the dimensions for the animation.
openDuration	280	number	Opening the animation duration (ms).
closeDuration	280	number	Closing the animation duration (ms).
imgLoaded	-	boolean	You have to pass the result of img tag “onload” event or “onLoadingComplete” from the NextJS Component. Highly recommended when you make the transition between images.
modalSelector	-	string	It accepts querySelector selectors. To prevent flickering when you have the transition between images. You can do the same by using “modalRef”.
modalRef(ref)	-	React.RefObject	Accept the ref which have access to your Modal. To prevent flickering when you have the transition between images. You can do the same by using “modalSelector”.
hideFirstElem	true	boolean	It hides the first element when the modal is opened.
disableOpenAnimation	false	boolean	Set it to ‘true’ when you have to disable the opening of the animation.
disableCloseAnimation	false	boolean	Set it to true when you have to disable closing the animation.
openEasing	“ease-in”	string	Open the animation easing function. You can pass here e.g. cubic-bezier.
closeEasing	“ease-out”	string	Close the animation easing function. You can pass here e.g. cubic-bezier.
transformOrigin	center	string	transformOrigin CSS property value.
pauseOnOpen	false	boolean	A property for debugging. Pause an element before the animation starts. It works on the firstElemRef (opening the animation).
pauseOnClose	false	boolean	A property for debugging. Pause an element before the animation starts. It works on modalElemRef (close animation).
onOpenAnimationStart	-	function(element: HTMLElement)	Called when the opening animation is ready to start. It is provided a reference to the DOM element (modalElemRef) being transitioned as the argument.
onOpenAnimationEnd	-	function(element: HTMLElement)	Called when the opening animation is finished. It is provided a reference to the DOM element (modalElemRef) being transitioned as the argument.
onCloseAnimationStart	-	function(element: HTMLElement)	Called when the closing animation is ready to start. It is provided a reference to the DOM element (firstElemRef) being transitioned as the argument.
onCloseAnimationEnd	-	function(element: HTMLElement)	Called when the closing animation is finished. It is provided a reference to the DOM element (firstElemRef) being transitioned as the argument.
activeIndex	-	number / string	This must be the ID of your active element. You need this when you want the first element to become visible after changing its ID. If you have hideFirstElem set to false, you don't need it.

Functions that hook returns

Hook returns a function called "restartAnimation", which can be used to restart the animation. A practical example of its usage is when you have a lightbox and you want to restart the animation each time you change a slide.

Possible problems

An element is being covered by others

Solution: use the callback functions (onOpenAnimationStart, onOpenAnimationEnd, onCloseAnimationStart, onCloseAnimationEnd) to change the “z-index” property during the animation.

Container with the overflow: "hidden" property covers an element

Solution: use the callback functions (onOpenAnimationStart, onOpenAnimationEnd, onCloseAnimationStart, onCloseAnimationEnd) to change the “overflow” property during the animation.

Sometimes the animation doesn't start(when use images)

Solution: When you use the images you have to pass the “imgLoaded” prop to hook.

Elements are distorted during the animation

Solution: Check that you are not animating any parent elements that are larger than the elements you want to animate. You can use the prop “pauseOnOpen” or “PauseOnClose”. During the animation the element should perfectly cover the element that is going to be under it.
