Vue 3 Lottie

Add Lottie animations to your Vue 3 or Nuxt 3 application.

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.

Upgrade to v3.x

If you are using version 2.x of vue3-lottie you should upgrade to version 3.x. You can do this by running the Installation and Usage command below. This add better support for Typescript. There is also a change with the dist/style.css import (it's been removed) so take a look at the new documentation for instructions on how to migrate to this package.

Installation and Usage

Vue 3

  • You can install vue3-lottie over yarn or npm. lottie-web is a dependency of vue3-lottie and should be automatically installed when you install vue3-lottie.

If you are using npm:

npm install vue3-lottie@latest --save

If you are using yarn:

yarn add vue3-lottie@latest
  • Register the component in your Vue 3 application.

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')

If you get an error with TS, try use(Vue3Lottie, { name: "Vue3Lottie" })

To define global components for Volar type-checking you will need to add:

// components.d.ts
declare module '@vue/runtime-core' {
  export interface GlobalComponents {
    LottieAnimation: typeof import('vue3-lottie')['Vue3Lottie']
  }
}
export {}

If needed rename component to use:

app.use(Vue3Lottie, { name: 'LottieAnimation' }) // use in template <LottieAnimation />
  • name string (default: 'Vue3Lottie') - set custom component name

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="AstronautJSON" :height="200" :width="200" />
</template>

<script>
import { Vue3Lottie } from 'vue3-lottie'

import AstronautJSON from './astronaut.json'

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

Nuxt 3

This is still experimental. Will be updated soon.

  • You can install vue3-lottie over yarn or npm. lottie-web is a dependency of vue3-lottie and should be automatically installed when you install vue3-lottie.

If you are using npm:

npm install vue3-lottie@latest --save

If you are using yarn:

yarn add vue3-lottie@latest
  • Create a folder called plugins at the root of your project.
  • Create a file named Vue3Lottie.client.ts inside the plugins directory.
  • Add the following code to the Vue3Lottie.client.ts file.
import { Vue3Lottie } from 'vue3-lottie'

export default defineNuxtPlugin((nuxtApp) => {
  nuxtApp.vueApp.component('Vue3Lottie')
})

If you get an error with TS, try component(Vue3Lottie, { name: "Vue3Lottie" })

This should register as a global component that you can call anywhere in your app under the tag.

I would recommend using a <client-only> parent tag to ensure that the animation only loads in on the client side.

<client-only>
  <Vue3Lottie
    animationLink="https://assets10.lottiefiles.com/packages/lf20_soCRuE.json"
    :height="200"
    :width="200"
  />
</client-only>

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
noMargin Boolean false Prevent the lottie from auto centering in the container. This gives you better control on placement within your UI
scale Number 1 Scale the animation (might cause blurriness)
assetsPath String "" URL to the image asset you need to use in your Lottie animation
renderer String "svg" Set the renderer
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.
  • onAnimationLoaded
    • This event is fired when the animation has loaded. This should let you know when you can start referencing the methods for the component.

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.
  • updateDocumentData(documentData, index)
    • This method updates text on text layers. Refer to the official docs for how to use this method.
