Lottie component for React Native (iOS, Android, and Windows)

Lottie is an ecosystem of libraries for parsing Adobe After Effects animations exported as JSON with bodymovin and rendering them natively!

For the first time, designers can create and ship beautiful animations without an engineer painstakingly recreating it by hand.

We've made some significant updates in version 6 that may impact your current setup. To get all the details about these changes, check out the migration guide.

Stay informed to ensure a seamless transition to the latest version. Thank you!

• Install lottie-react-native (latest):

yarn add lottie-react-native

Go to your ios folder and run:

pod install

• Install lottie-react-native (latest):

yarn add lottie-react-native

• Add dependencies for web players:

yarn add @lottiefiles/dotlottie-react

#include <winrt/LottieReactNative.h>

...

PackageProviders().Append(winrt::LottieReactNative::ReactPackageProvider(winrt::AnimatedVisuals::LottieCodegenSourceProvider()));

<!-- .vcxproj or .csproj -->
<ItemGroup>

<LottieView source={"MyAnimation"} style={{width: "100%", height: "100%"}} />

Lottie iOS and Lottie React Native do not collect any data. We provide this notice to help you fill out App Privacy Details. Both libraries provide privacy manifests (Lottie iOS's privacy manifest, Lottie React Native's privacy manifest) which can be included in your app and are available as bundle resources within the libraries by default.

Lottie can be used in a declarative way:

import React from "react";
import LottieView from "lottie-react-native";

export default function Animation() {
  return (
    <LottieView
      source={require("../path/to/animation.json")}
      style={{width: "100%", height: "100%"}}
      autoPlay
      loop
    />
  );
}

Additionally, there is an imperative API which is sometimes simpler.

import React, { useEffect, useRef } from "react";
import LottieView from "lottie-react-native";

export default function AnimationWithImperativeApi() {
  const animationRef = useRef<LottieView>(null);

  useEffect(() => {
    animationRef.current?.play();

    // Or set a specific startFrame and endFrame with:
    animationRef.current?.play(30, 120);
  }, []);

  return (
    <LottieView
      ref={animationRef}
      source={require("../path/to/animation.json")}
      style={{width: "100%", height: "100%"}}
    />
  );
}

Lottie's animation view can be controlled by either React Native Animated or Reanimated API.

import React, { useEffect, useRef, Animated } from "react";
import { Animated, Easing } from "react-native";
import LottieView from "lottie-react-native";

const AnimatedLottieView = Animated.createAnimatedComponent(LottieView);

export default function ControllingAnimationProgress() {
  const animationProgress = useRef(new Animated.Value(0));

  useEffect(() => {
    Animated.timing(animationProgress.current, {
      toValue: 1,
      duration: 5000,
      easing: Easing.linear,
      useNativeDriver: false,
    }).start();
  }, []);

  return (
    <AnimatedLottieView
      source={require("../path/to/animation.json")}
      progress={animationProgress.current}
      style={{width: "100%", height: "100%"}}
    />
  );
}

Changing color of layers:

NOTE: This feature may not work properly on Android. We will try fix it soon.

import React from "react";
import LottieView from "lottie-react-native";

export default function ChangingColorOfLayers() {
  return (
    <LottieView
      source={require("../path/to/animation.json")}
      colorFilters={[
        {
          keypath: "button",
          color: "#F00000",
        },
        {
          keypath: "Sending Loader",
          color: "#F00000",
        },
      ]}
      style={{width: "100%", height: "100%"}}
      autoPlay
      loop
    />
  );
}

You need to modify your metro.config.js file accordingly by adding lottie extension to the assetExts array:

const { getDefaultConfig, mergeConfig } = require("@react-native/metro-config");

const defaultConfig = getDefaultConfig(__dirname);

/**
 * Metro configuration
 * https://facebook.github.io/metro/docs/configuration
 *
 * @type {import('metro-config').MetroConfig}
 */
const config = {
  resolver: {
    assetExts: [...defaultConfig.resolver.assetExts, "lottie"],
  },
};

module.exports = mergeConfig(getDefaultConfig(__dirname), config);

Create a file in the following path __mocks__/lottieMock.js and add the following code:

module.exports = "lottie-test-file-stub";

Then add the following to your jest.config.js file:

module.exports = {
  ...
  moduleNameMapper: {
    ...,
    '\\.(lottie)$': '<rootDir>/jest/__mocks__/lottieMock.js',
  },
  ...
}

You can find the full list of props and methods available in our API document. These are the most common ones:

Not all After Effects features are supported by Lottie. If you notice there are some layers or animations missing check this list to ensure they are supported.

When it comes to animations, please validate that your animation file is compliant with the standard (for example, that it doesn't have floating number in places that require integers). If you have an animation that is not working as expected, it is always recommended that you look at the Logcat output on Android and the console on iOS, as both ecosystems will have logs attached in case of an error that usually highlights what has gone wrong.
