AM LottiePlayer Light

Awesome Vector Animations

This is a light version of of @aarsteinmedia/dotlottie-player. If you only need SVG renderer (not HTML or Canvas) and don't need to convert JSON to dotLottie or combine animations on the fly, this one is for you. This version supports dotLottie format as well as JSON, and you can toggle between multiple animations in a single file.

The component is compatible with server side rendering, and like any good web component it's framework agnostic.

Installation

In HTML

<script src="https://unpkg.com/@aarsteinmedia/dotlottie-player-light@latest/dist/index.js"></script>
<script src="https://github.com/aarsteinmedia/dotlottie-player-light/raw/main/node_modules/@aarsteinmedia/dotlottie-player-light/dist/index.js"></script>

In JavaScript or TypeScript

  1. Install using npm or yarn:
npm install --save @aarsteinmedia/dotlottie-player-light
  1. Import in your app:
import '@aarsteinmedia/dotlottie-player-light'

Usage

Add the element dotlottie-player to your markup and point src to a Lottie animation of your choice. If you're working in SSR environments like Next.js or Nuxt.js, it might be a good idea to set reflective booleans (like autoplay, controls and loop) to an empty string instead of true – to mimic how modern browsers treats these values in markup, as opposed to how Node.js treats them. This way you avoid hydration errors.

<dotlottie-player
  autoplay=""
  controls=""
  subframe=""
  loop=""
  src="https://storage.googleapis.com/aarsteinmedia/am.lottie"
  style="width: 320px; margin: auto;"
>
</dotlottie-player>

To set animations programmatically, use the load() method.

const lottiePlayer = document.querySelector('dotlottie-player')
lottiePlayer.load('https://storage.googleapis.com/aarsteinmedia/am.lottie')

Control playback of multiple animations in a single file

Use the full version of this package to combine multiple animations into one file. To control the playback you can either use the next() and prev() methods, the navigation buttons in the controls or the parameter multiAnimationSettings in the markup.

In the example below the first animation will play once, and then the next animation will loop:

<dotlottie-player
  id="find-me"
  subframe=""
  src="https://github.com/aarsteinmedia/dotlottie-player-light/raw/main/path/to/combined-animations.lottie"
>
</dotlottie-player>  
  const player = document.querySelector('#find-me')
  player?.setMultiAnimationSettings(
    [
      {
        autplay: true
      },
      {
        autoplay: true,
        loop: true
      }
    ]
  )

Angular

  1. Import the component in app.component.ts.
import { Component } from '@angular/core'
import '@aarsteinmedia/dotlottie-player-light'

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  title = 'your-app-name';
}
  1. Add the player to your html template.

React.js / Next.js

If you've already imported the library in a parent component, you don't need to import it again in children of that component. If you want to assign the element a CSS class note that you need to use the class namespace, and not className.

import '@aarsteinmedia/dotlottie-player-light'

function App() {
  return (
    <dotlottie-player
      class="your-class-name"
      src="https://storage.googleapis.com/aarsteinmedia/am.lottie"
      autoplay=""
      controls=""
      subframe=""
      loop=""
      style={{
        width: '320px',
        margin: 'auto'
      }}
    />
  )
}

export default App

If you're using TypeScript and want to assign the component a ref, you can do it like this:

import { useRef } from 'react'
import '@aarsteinmedia/dotlottie-player-light'
import type DotLottiePlayer from '@aarsteinmedia/dotlottie-player-light'

function App() {
  const animation = useRef<DotLottiePlayer | null>(null)
  return (
    <dotlottie-player
      ref={animation}
      src="https://storage.googleapis.com/aarsteinmedia/am.lottie"
    />
  )
}

export default App

Vue.js / Nuxt.js (using Vite.js)

Compared to React and Angular there's a couple of extra steps, but surely nothing too daunting.

  1. Declare the dotlottie-player tag as a custom element, to prevent Vue from attempting to resolve it.

In Vue.js

vite.config.ts:

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'

export default defineConfig({
  plugins: [
    vue({
      template: {
        compilerOptions: {
          isCustomElement: (tag: string) => ['dotlottie-player'].includes(tag),
        }
      }
    })
  ]
})

In Nuxt.js

nuxt.config.ts:

export default defineNuxtConfig({
  vue: {
    compilerOptions: {
      isCustomElement: (tag: string) => ['dotlottie-player'].includes(tag),
    }
  }
})
  1. Import/initiate the component.

In Vue.js

main.ts:

import { createApp } from 'vue'
import DotLottiePlayer from '@aarsteinmedia/dotlottie-player-light'
import App from './App.vue'

const app = createApp(App)
app.component('DotLottiePlayer', DotLottiePlayer)

In Nuxt.js

Create a plugins folder in your root if it doesn't exist already, add a file named dotlottie-player-light.js:

import DotLottiePlayer from '@aarsteinmedia/dotlottie-player-light'

export default defineNuxtPlugin(({ vueApp }) => {
  vueApp.component('DotLottiePlayer', DotLottiePlayer)
})
  1. The component can now be used in your pages or components template tags.
<template>
  <dotlottie-player
    src="https://storage.googleapis.com/aarsteinmedia/am.lottie"
    autoplay=""
    controls=""
    subframe=""
    loop=""
    style="width: 320px; margin: auto;"
  />
</template>
