What is @lottiefiles/react-lottie-player?

@lottiefiles/react-lottie-player is a React component library that allows you to easily integrate Lottie animations into your React applications. It provides a simple and flexible way to control Lottie animations, including playing, pausing, stopping, and looping animations.

What are @lottiefiles/react-lottie-player's main functionalities?

Basic Animation Playback

This feature allows you to play a Lottie animation automatically and loop it. The `autoplay` and `loop` props control the playback behavior, and the `src` prop specifies the URL of the Lottie animation file.

import { Player } from '@lottiefiles/react-lottie-player';

function App() {
  return (
    <Player
      autoplay
      loop
      src="https://assets7.lottiefiles.com/packages/lf20_5x8LBM.json"
      style={{ height: '300px', width: '300px' }}
    />
  );
}

Controlling Animation Playback

This feature allows you to control the playback of a Lottie animation using buttons. The `ref` prop is used to get a reference to the Player component, which is then used to call the `play`, `pause`, and `stop` methods.

import { Player } from '@lottiefiles/react-lottie-player';
import { useRef } from 'react';

function App() {
  const playerRef = useRef(null);

  return (
    <div>
      <Player
        ref={playerRef}
        src="https://assets7.lottiefiles.com/packages/lf20_5x8LBM.json"
        style={{ height: '300px', width: '300px' }}
      />
      <button onClick={() => playerRef.current.play()}>Play</button>
      <button onClick={() => playerRef.current.pause()}>Pause</button>
      <button onClick={() => playerRef.current.stop()}>Stop</button>
    </div>
  );
}

Customizing Animation Speed

This feature allows you to customize the playback speed of a Lottie animation. The `setPlayerSpeed` method is used to set the speed of the animation, with 1 being the normal speed.

import { Player } from '@lottiefiles/react-lottie-player';
import { useRef } from 'react';

function App() {
  const playerRef = useRef(null);

  return (
    <div>
      <Player
        ref={playerRef}
        src="https://assets7.lottiefiles.com/packages/lf20_5x8LBM.json"
        style={{ height: '300px', width: '300px' }}
      />
      <button onClick={() => playerRef.current.setPlayerSpeed(0.5)}>0.5x Speed</button>
      <button onClick={() => playerRef.current.setPlayerSpeed(1)}>1x Speed</button>
      <button onClick={() => playerRef.current.setPlayerSpeed(2)}>2x Speed</button>
    </div>
  );
}

Get Player instance

To call methods on the instance of the Player component. you may get a reference to the component and call the methods on ref.current. This is esentially reacts way of doing a document.getElementById(); You may then use this ref ie: player in the example below to call methods that are described in this documentation. See ref in react documentation

import React from 'react';
import { Player } from '@lottiefiles/react-lottie-player';

class App extends React.Component {
  constructor(props) {
    super(props);
    this.player = React.createRef(); // initialize your ref
  }
  render() {
    return (
      <Player
        ref={this.player} // set the ref to your class instance
        autoplay={false}
        loop={true}
        controls={true}
        src="https://assets3.lottiefiles.com/packages/lf20_XZ3pkn.json"
        style={{ height: '300px', width: '300px' }}
      ></Player>
    );
  }
}

export default App;

Get Lottie instance

The lottieRef prop returns the Lottie instance which you can use to set data and call methods as described in the bodymovin documentation.

import React from 'react';
import { Player } from '@lottiefiles/react-lottie-player';

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = { lottie: null }; // initialize your state
  }

  render() {
    return (
      <Player
        lottieRef={instance => {
          this.setState({ lottie: instance }); // the lottie instance is returned in the argument of this prop. set it to your local state
        }}
        autoplay={false}
        loop={true}
        controls={true}
        src="https://assets3.lottiefiles.com/packages/lf20_XZ3pkn.json"
        style={{ height: '300px', width: '300px' }}
      ></Player>
    );
  }
}

export default App;

Listening for events

import React from 'react';
import { Player } from '@lottiefiles/react-lottie-player';

class App extends React.Component {
  constructor(props) {
    super(props);
    this.player = React.createRef();
  }

  doSomething() {
    this.player.current.play(); // make use of the player and call methods
  }

  render() {
    return (
      <Player
        onEvent={event => {
          if (event === 'load') this.doSomething(); // check event type and do something
        }}
        ref={this.player}
        autoplay={false}
        loop={true}
        controls={true}
        src="https://assets3.lottiefiles.com/packages/lf20_XZ3pkn.json"
        style={{ height: '300px', width: '300px' }}
      ></Player>
    );
  }
}
