This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including react-native-spruce with all npm packages installed. Try it out:

react-native-spruce lists no main file and has no index.js, so it can't be directly required. If this is a mistake, please let us know. It may however contain internal files that you can require manually:

// require("react-native-spruce/[??]")

React Native Bridge for Spruce Library

PRs Welcome

React Native Spruce - iOS & Android

Spruce is a lightweight animation library that helps choreograph the animations on the screen. With so many different animation libraries out there, developers need to make sure that each view is animating at the appropriate time. Spruce can help designers request complex multi-view animations and not have the developers cringe at the prototype.

It provides a React Native Bridge around native spruce library. Here is a quick example of how you can Spruce up your screens!

Before we dive into on how to use this library. We would like to thank all the contributor of willowtreeapps/spruce-android & willowtreeapps/spruce-ios for providing such a awesome nice, cool library

Note: Currently on iOS it is not supported due to unavailable of Spruce Objective-C wrappers, please refer issue: 101

Getting started

$ npm install react-native-spruce --save

$ react-native link react-native-spruce

  • Android

    • Please copy below snippet in your app build.gradle file:
buildscript {
    repositories {

allprojects {
    repositories {

Note: Android SDK 27 > is supported


import {
} from "react-native-spruce";

// TODO: What to do with the module?

render () {
  let sortWith = new CorneredSort(100);
  let animateWith = DefaultAnimations.shrinkAnimator(1000)

  <Spruce sortWith={sortWith} animateWith={animateWith} animator={{ propertyName: "translationX", values: [5000, 0], duration: 800 }}>
    <View />

Using a SortFunction

Luckily, RNSpruce comes with 8 SortFunction implementations with a wide open possibility to make more! Use the SortFunction to change the order in which views animate. Consider the following example:

let sort = new LinearSort(/*interObjectDelay=*/100L, /*reversed=*/false, LinearSort.Direction.TOP_TO_BOTTOM);

To make sure that developers can use RNSpruce out of the box, we included about 8 stock SortFunction implementations. These are some of the main functions we use at WillowTree and are so excited to see what others come up with!

  • DefaultSort
let sort = new DefaultSort(/*interObjectDelay=*/100L);
  • LinearSort
let sort = new LinearSort(/*interObjectDelay=*/100L, /*reversed=*/false, LinearSort.Direction.TOP_TO_BOTTOM);
  • CorneredSort
let sort = new CorneredSort(/*interObjectDelay=*/100L, /*reversed=*/false, CorneredSort.Corner.TOP_LEFT);
  • RadialSort
let sort = new RadialSort(/*interObjectDelay=*/100L, /*reversed=*/false, RadialSort.Position.TOP_LEFT);
  • RandomSort
let sort = new RandomSort(/*interObjectDelay=*/100L);
  • InlineSort
let sort = new InlineSort(/*interObjectDelay=*/100L, /*reversed=*/false, LinearSort.Direction.TOP_TO_BOTTOM);
  • ContinousSort
let sort = new ContinousSort(/*interObjectDelay=*/100L, /*reversed=*/false, ContinousSort.Position.TOP_LEFT);

Stock Animators

To make everybody's lives easier, the stock animators perform basic View animations that a lot of apps use today. Mix and match these animators to get the core motion you are looking for.

  • DefaultAnimations.growAnimator(duration:number)
  • DefaultAnimations.shrinkAnimator(duration:number)
  • DefaultAnimations.fadeAwayAnimator(duration:number)
  • DefaultAnimations.fadeInAnimator(duration:number)
  • DefaultAnimations.spinAnimator(duration:number)

Experiment which ones work for you! If you think of anymore feel free to add them to the library yourself!


Any type of contribution will be very much appreciated
