Lottie-Web-Vue

Lottie-web-vue is an Airbnb Lottie-web component for Vue.js projects

---

Airbnb's Lottie-web is a library for rendering animations exported from Adobe After Effects using the BodyMovin plugin. This package allows you to easily import animation files (available in .json format) into your Vue.js project.

Vue 3 + Typescript Support

With latest lottie-web-vue 2.x.x release the library now supports Vue 3 + Typescript typing! If you are using Vue 2.x ensure to use version 1.2.1 (see below)

npm install lottie-web-vue

Vue 2

Please install v1.2.1 of the plugin. This plugin will focus on maintaining Vue 3 now that it has been officially released.

npm install lottie-web-vue@1.2.1 

Animations

You can browse and download animations from LottieFiles. First, find an animation you like > signup > click export JSON and save to your project. In vue you can save these under assets and then use require('@/assets/animation.json') to load them into the LottieAnimator as part of the lottie-web-vue component.

Installation

Add lottie-web-vue to your Vue 3.x project package using:

npm install --save lottie-web-vue

or

yarn add lottie-web-vue

To use Vue 2.x use:

npm install lottie-web-vue@1.2.1 

Vue 2.x

Please install v1.2.1 of the plugin (this will no longer be maintained)

import Vue from 'vue'
import LottieAnimation from 'lottie-web-vue'
 
Vue.use(LottieAnimation); // add lottie-animation to your global scope
 
new Vue({
  render: h => h(App)
}).$mount('#app')

Usage

Basic:

<script setup lang="ts">
  import { onMounted, ref } from "vue"
  import { LottieAnimation } from "lottie-web-vue"
  import WatermelonJSON from "./assets/watermelon.json"

  let anim = ref()

  onMounted(() => {
    setTimeout(() => {
      console.log(anim.value.goToAndPlay(150, true))
      anim.value
    }, 500)
  })
</script>
<template>
  <LottieAnimation 
    :animation-data="WatermelonJSON"
    :auto-play="true"
    :loop="true"
    :speed="1"
    ref="anim" />
</template>

Full available props and events:

<script setup>
  import { onMounted, ref } from "vue"
import { LottieAnimation } from "lottie-web-vue"
import WatermelonJSON from "./assets/watermelon.json"

let anim = ref()

onMounted(() => {
  setTimeout(() => {
    console.log(anim.value.goToAndPlay(150, true))
    anim.value
  }, 500)
})

// called after each loop
const loopComplete = () => {
  console.log('Loop complete')
}

// called after first loop
const complete = () => {
  console.log('First loop complete')
}

// called after first frame entered
const enterFrame = () => {
  console.log('Entered first frame')
}

// called after segment started
const segmentStart = () => {
  console.log('Segment started')
}

// called after animation stopped
const stopped = () => {
  console.log('Stopped')
}
</script>
<template>
  <LottieAnimation
    ref="anim"
    :animation-data="WatermelonJSON"
    :loop="true"
    :auto-play="true"
    :speed="1"
    @loopComplete="loopComplete"
    @complete="complete"
    @enterFrame="enterFrame"
    @segmentStart="segmentStart"
    @stopped="stopped"/>
</template>

Props

The component has a number of props you can use to control the animation playback.

You must pass animationData to load the animation prior to the component being played.

animationData

Type: Object
Required: true

Include animation data from an import or require statement that imports the .json file from your assets folder. e.g. require('@/assets/animation.json') (save you animation as a.json file and put under src/assets in your project)

loop

Type: [Boolean, Number]
Required: false
Default: false

True: Animation continously loops False: Animation plays only once [number e.g. 3]: Animation plays N number of times before stopping (pass an integer)

autoPlay

Type: Boolean
Required: false
Default: true

True: Animation will play as soon as it has finished loading False: Animation will play only when you call this.$refs.lottieAnimation.play() (see below for playback controls)

speed

Type: Number
Required: false
Default: 1

The speed that the animation will play back.

Events

You can listen for events emitted by the component by using the @ syntax, passing in the parent method you wish to trigger. For more documentation about the Lottie-web events see here.

@loopComplete

Fired once a complete loop of the animation has occurred

@complete

Fired once the animation has completed (only fired when loop = false)

@enterFrame

As each frame is played this event is fired. Warning - this fires very frequently.

@segmentStart

Event is fired when the animation enters each animation segment.

@stopped

Playing the animation using goToAndStop() function will raise an event once the animation has stopped at the designated frame.

Methods

You can call animation playback methods directly on the component if you wish to trigger playback on an event (i.e. when a user clicks the button, play the animation). You need to use the this.$refs syntax and give your LottieAnimation a ref id to use in the this.$refs.[your-name-here].

<script setup>
  import { LottieAnimation } from "lottie-web-vue"
  import WatermelonJSON from "./assets/watermelon.json"
</script>
<template>
  <LottieAnimation
    ref="anim"
    :animationData="animation"
  />
</template>

Once your component (in the parent view) has a ref id you can then use this in a method of your choosing:

... // in your parent .vue file
<script setup lang="ts">
  const buttonClicked = () => {
    this.$refs.anim.play() // .play, .pause, .stop available
  }
</script>

Play

Using this.$refs.anim.play() will play the animation.

Pause

Using this.$refs.anim.pause() will pause the animation.

Stop

Using this.$refs.anim.stop() will stop the animation.

setSpeed [number: speed]

Using this.$refs.anim.setSpeed(2) you can set the playback speed to 2. Default speed is set to 1.

• number: Set the speed playback rate

goToAndStop [Position: frame number or seconds, isFrame: boolean]

Using this.$refs.anim.goToAndStop(10, true you can set the specific frame you wish the animation to stop at. Pass in the frame number or seconds to play and if the first value is a frame or a time as true/false. This function will raise an emit (add @stopped="Yourfunction()" to your lottie-animation listen for it).

• position: numeric value (specific frame number or second to stop)
• isFrame: defines if first argument is a time based value or a frame based (default false).

goToAndPlay [Position: frame number or seconds, isFrame: boolean]

Using this.$refs.anim.goToAndPlay(50, true) allows you to specify the start time of the animation in either frame number (passing isFrame true/false if value is a frame or in seconds).

• position: numeric value (specific frame number or second to stop)
• isFrame: defines if first argument is a time based value or a frame based (default false).

setDirection [Direction: -1: reverse, 1: forwards]

Using this.$refs.anim.setDirection(-1) you can reverse your animation. You can pass in either AnimationDirection. to reverse the animation or 1 to play forwards. Default playback is 1.

• Direction:
  • -1 (reverse playback)
  • 1 (play forwards)

getDuration [inFrames: true/false]

Using this.$refs.anim.getDuration(true) you can retrieve the current duration of the animation in frames or seconds (false). If you pass true, function returns duration in frames, if false, duration is passed back in seconds. Default is false (returned in seconds).

• inFrames: boolean to request current duration in either frames (inFrames: true) or in seconds (inFrames: false)

destroy

Using this.$refs.anim.destroy() you can destroy the animation from the DOM.

Options API Example

See here for an example:

<template>
  <div id="app">
    <LottieAnimation
      ref="anim"
      :animationData="require('@/assets/animation.json')"
      :loop="true"
      :autoPlay="true"
      @loopComplete="loopComplete"
      @complete="complete"
      @enterFrame="enterFrame"
    />
  </div>
</template>

<script>
import LottieAnimation from 'lottie-web-vue'

export default {
  components: {
    LottieAnimation
  },
  mounted() {
    this.$refs.anim.play()
  },
  methods: {
    loopComplete() {
      console.log('loopComplete')
    },
    complete() {
      console.log('complete')
    },
    enterFrame() {
      console.log('enterFrame')
    }
  }
}
</script>

Vue 3 Composition API with Setup + Typescript

To use this in a Vue 3 project that uses the setup Composition API use the following:

Script setup

<script setup lang="ts">
import { onMounted, ref } from "vue"
import { LottieAnimation } from "lottie-web-vue"
import WatermelonJSON from "./assets/watermelon.json"

let anim = ref()

onMounted(() => {
  setTimeout(() => {
    console.log(anim.value.goToAndPlay(150, true))
    anim.value
  }, 500)
})

</script>
<template>
  <LottieAnimation
    ref="anim"
    :animation-data="WatermelonJSON"
    :loop="true"
    :auto-play="true"
    :speed="1"
    @loopComplete="loopComplete"
    @complete="complete"
    @enterFrame="enterFrame"
    @segmentStart="segmentStart"
    @stopped="stopped"/>
</template>
