vue3-lottie

Vue 3 Lottie

vue3-lottie was created to help developers add Lottie animations to their Vue 3 applications. In my search for a simple way to add Lottie animations to my Vue application I found a suprising lack of maintained solutions. vue3-lottie is a vue wrapper around the lottie-web library with a few additional features.

Installation

If you are using npm:

npm install vue3-lottie

If you are using yarn:

yarn add vue3-lottie

Usage

The most common use case is to register the component globally.

// main.js
import { createApp } from 'vue'
import Vue3Lottie from 'vue3-lottie'

createApp(App).use(Vue3Lottie).mount('#app')

Alternatively you can also import the component locally.

import Vue3Lottie from 'vue3-lottie'

export default {
  components: {
    Vue3Lottie,
  },
}

You can then use the component in your template

<template>
  <Vue3Lottie :animationData="DogJSON" :height="200" :width="200" />
</template>

<script>
import Vue3Lottie from 'vue3-lottie'
import DogJSON from './lotties/dog.json'

export default {
  components: {
    Vue3Lottie,
  },
  data() {
    return {
      DogJSON,
    }
  },
}
</script>

Props and options

More detailed explanations are provided in the documentation.

Prop	Type	Default Value	Description
animationData	Object	{}	The lottie animation data provided as a JSON object
animationLink	String	''	A URL link to the Lottie animation data (eg: Lottie Animation URL on lottiefiles.com)
width	Number or String	"100%"	Width of the lottie animation container (Numbers correspond to pixel values)
height	Number or String	"100%"	Height of the lottie animation container (Numbers correspond to pixel values)
speed	Number	"1"	Speed of the lottie animation
direction	String	"forward"	Animation play direction
loop	Number or Boolean	true	The number of instances that the lottie animation should run (true is infinite)
autoPlay	Boolean	true	Start animation on component load
delay	Number	0	Delay the animation play state by some milliseconds
pauseAnimation	Boolean	false	Prop to pass reactive variables so that you can control animation pause and play
pauseOnHover	Boolean	false	Whether to pause the animation on hover
playOnHover	Boolean	false	Whether to play the animation when you hover
backgroundColor	String	transparent	Background color of the container
rendererSettings	Object	{}	Options for if you want to use an existing canvas to draw (can be ignored on most cases)

Events

A few events are emitted from the component. Look at the Demos for examples.

• onComplete
  • If your animation has a finite amount of loops you can use this event to know when the animation has completed.
• onLoopComplete
  • If your animation has a finite amount of loops you can use this event to know when the animation has completed a loop.
• onEnterFrame
  • This event is fired every frame of the animation. There will be 60 events fired per second if your lottie animation runs at 60fps.
• onSegmentStart
  • This event is fired when the animation enters a segment.

Methods

You can control the animation with the following methods. These methods can be called by assigning a ref value to the vue3-lottie component. Look at the Demos for examples.

• play
  • Plays the animation
• pause
  • Pauses the animation
• stop
  • Stops the animation. This will also reset the animation to the first frame. Look at the demo for some examples.
• destroy
  • You can call this method to destroy the animation. It will remove the animation from the DOM.
• setSpeed(speed)
  • You can call this method to change the speed of your animation.
• setDirection(direction)
  • You can call this method to change the direction of your animation.
• getDuration(inFrames)
  • You can call this method to get the duration of your animation.
• goToAndStop(frameNumber, isFrames)
  • You can call this method to go to a specific frame of your animation. The animation will be stopped at the end of this call.
• goToAndPlay(frameNumber, isFrames)
  • You can call this method to go to a specific frame of your animation. The animation will be played from this frame.
• playSegments(segments, forceFlag)
  • You can call this method to play a specific segment of your animation.
• setSubFrame(subFrame)
  • You can call this method to set the subframe value.
