• createTimeline

Example usage

Things You could do with createAnimation

Things You could do with createTimeline

createAnimation

Returns all the properties returned by animate and some helper functions and state

Props returned my animate are null initially

function App() {
    const { play, getIsFinished, replay } = createAnimation(
        '.listItem',
        { y: -20, opacity: 1 },
        {
            delay: stagger(0.3),
            duration: 0.5,
            easing: [0.22, 0.03, 0.26, 1],
        },
    );

    // Play the animation on mount of the component
    onMount(() => {
        play();
    });

    return (
        // Replay the animation anytime by calling a function, anywhere
        <div class="App">
            <button disabled={!getIsFinished()} onClick={() => replay()}>
                Replay
            </button>

            <ul class="list">
                <li class="listItem">Item 1</li>
                <li class="listItem">Item 2</li>
                <li class="listItem">Item 3</li>
            </ul>
        </div>
    );
}

Instead of passing strings to select elements, you can also pass a ref :point_down:

let boxRef;
const { play, getIsFinished, replay } = createAnimation(
    () => boxRef, // Pass a Function that returns the ref
    { y: -20, scale: 1.2 },
    { duration: 1 },
);

return <div ref={boxRef}>BOX</div>;

API

const { play, replay, reset, getIsFinished, getAnimateInstance } = createAnimation(
    selector,
    keyframes,
    options,
    events,
);

createAnimation returns:

• play: plays the animation
• replay: Resets and plays the animation
• reset: resets the element to its original styling
• getIsFinished: is true when animation has finished playing
• getAnimateInstance: Animation Controls. Refer to motion one docs for more.

createAnimation accepts:

• selector - The target element, can be string or a ref

• keyframes - Element will animate from its current style to those defined in the keyframe. Refer to motion's docs for more.

• options - Optional parameter. Refer to motion doc's for the values you could pass to this.

• events - Pass functions of whatever you want to happen when a event like onFinish happens.

  events usage example

  const { play, getIsFinished, replay } = createAnimation(
      '.listItem',
      { y: -20, opacity: 1 },
      {
          delay: stagger(0.3),
          duration: 0.5,
      },
      {
          onFinish: () => {
              // Whatever you want to do when animation finishes
          },
      },
  );

createTimeline

Create complex sequences of animations across multiple elements.

returns getTimelineInstance (Animation Controls) that are returned by timeline and some helper functions and state

Props returned by timeline are null initially

function App() {
    let gifRef;
    const { play, getIsFinished, replay } = createTimeline(
        [
            // You can use Refs too!
            [() => gifRef, { scale: [0, 1.2], opacity: 1 }],
            ['.heading', { y: [50, 0], opacity: [0, 1] }],
            ['.container p', { opacity: 1 }],
        ],
        { duration: 2 },
    );

    onMount(() => {
        play();
    });

    return (
        <div class="App">
            <button disabled={!getIsFinished()} onClick={() => replay()}>
                Replay
            </button>

            <div class="container">
                <img ref={gifRef} class="gif" src={Image} alt="mind explosion gif" />
                <div>
                    <h1 class="heading">Tanvesh</h1>
                    <p>@sarve__tanvesh</p>
                </div>
            </div>
        </div>
    );
}

API

const { play, replay, reset, getIsFinished, getTimelineInstance } = createTimeline(
    sequence,
    options,
    events,
);

createTimeline returns:

• play: plays the animation
• replay: Resets and plays the animation
• reset: resets the element to its original styling
• getIsFinished: is true when animation has finished playing
• getTimelineInstance: Animation Controls. Refer to motion one docs for more.

createTimeline accepts:

• sequence - sequence is an array, defines animations with the same settings as the animate function. In the arrays, Element can be either a string or a ref. You can refer to sequence docs for more on this.
• options - Optional parameter. Refer to motion doc's for the values you could pass to this.
• events - Pass functions of whatever you want to happen when a event like onFinish happens. Exactly same as createAnimation's onFinish.
