Use native solutions to achieve smooth animations and gesture-driven interface at 60FPS.


The following article is part of The Ultimate Guide to React Native Optimization and covers the sixth point of this guide: how to achieve animations at 60FPS.

Why is it important?

Nice and smooth animations are a crucial part of the success of your app. They improve the perception of them and make them more pleasant for your users. But, when done incorrectly, they can seriously damage your products by slowing them down. In this article, we describe some useful practices on how to achieve 60FPS animations in React Native with no harm to the speed of your app.

The previous parts of our guide discuss:

Be sure to check them out. Now let’s move to the main topic.

Animate at 60FPS no matter what

Issue: JS-driven animations are occupying the bridge traffic and slow down the application.

Mobile users are used to smooth and well-designed interfaces that quickly respond to their interactions and provide prompt visual feedback. It is one of these things that is not really the case when it comes to web development but makes the difference on mobile. As a result, applications have to register a lot of animations in many places that will have to run while other work is happening.

60fps animation in react native

As we know from the previous section, the amount of information that can be passed over through the bridge is limited. There’s no built-in priority queue as of now. In other words, it is on you to structure and design your application in a way that both the business logic and animations can function without any disruptions. This is different from the way we are used to perform animations. For example, on iOS, the built-in APIs offer unprecedented performance and are always scheduled with the appropriate priority. Long story short – we don’t have to worry much about ensuring they’re running at 60 FPS.

With React Native, this story is a bit different. If you do not think about your animations top-down beforehand and choose the right tools to tackle this challenge, you’re on the best way to run into dropped frames sooner or later.

Janky or slow animations affect the perception of the app, making it look slow and unfinished

In today’s world of a sea of applications, providing smooth and interactive UI might be one of your only ways to win over the customers that are looking to choose the app to go.

If your application fails to provide a responsive interface that works well with the user interactions (such as gestures), not only it may affect the new customers, but also decrease the ROI and user sentiment.

Mobile users like the interfaces that follow them along and that look top-notch and ensuring the animations are always running smoothly is a fundamental part that builds such experience.

Solution: If it’s possible, use native and correct animations

One-off animations

Enabling usage of native driver is the easiest way of improving your animations performance quickly. However, the subset of style props that can be used together with native driver is limited. You can use it with non-layout properties like transforms and opacity. It will not work with colors, height, and others. Those are enough to implement most of the animations in your app because you usually want to show/hide something or change its position.

Enabling native driver for opacity animation

For more complex use cases, you can use React Native Reanimated library. It’s API is compatible with basic Animated library and also introduce a set of more low-level functions to control your animations. What’s more important, it introduces the possibility to animate all possible style props with native driver. So animating height or color will no longer be an issue. However, transform and opacity animations still will be slightly faster since they are GPU accelerated. But regular users should not see any difference.

Gesture driven animations

The most desired effect that can be achieved with animations is being able to control animation with a gesture. For your customers, this is the most enjoyable part of the interface. It builds a strong sentiment and makes the app feel very smooth and responsive. Plain React Native is very limited when it comes to combining gestures with native driven animations. You can utilize ScrollView scroll events to build things like smooth collapsible header.

For more sophisticated use cases there is an awesome library – React Native Gesture Handler – which allows you to handle different gestures natively and interpolate those into animations. You can build a simple swipeable element by combining it with Animated. However it will still require JS callbacks, but there is a remedy for that!

The most powerful pair of tools for gesture-driven animations is the usage of Gesture Handler combined with Reanimated. Those were designed to work together and give the possibility to build complex gesture-driven animations that are fully calculated on the native side. The only limitation here is your imagination (and coding skills, since Reanimated low-level API is not so straightforward).

Low-level handling of gestures might not be a piece of cake, but fortunately, there are already 3rd party libraries that utilize mentioned tools and expose CallbackNodes. CallbackNode is nothing more than an Animated.Value, but it is derived from specific gesture behavior. Its value range is usually from 0 to 1, which follows the progress of the gesture. You can interpolate the values to animated elements on the screen. A great example of libraries that expose CallbackNode are reanimated-bottom-sheet and react-native-tab-view.

Giving your JS operations lower priority

It is not always possible to fully control the way animations are implemented. For example, React Navigation uses a combination of React Native Gesture Handler and Animated which still needs JavaScript to control the animation runtime. As a result, your animation may start flickering if the screen you are navigating to loads a heavy UI. Fortunately, you can postpone the execution of such actions using InteractionManager.

This handy React Native module allows you to execute any code after all running animations are finished. In practice, you can show a placeholder, wait for the animation to finish, and then render the actual UI. It would make your JavaScript animations run smoothly and avoid interruptions by other operations. Usually smooth enough to provide a great experience.

Benefits: Enjoy smooth animations and gesture-driven interface at 60 FPS

There’s no one single right way of doing animations in React Native. The ecosystem is full of different libraries and approaches to handling interactions. The ideas suggested in this section are just recommendations to encourage you to not take the smooth interface for granted.

What is more important is painting that top-down picture in your head of all interactions within the application and choosing the right ways of handling them. There are cases where JavaScript-driven animations will work just fine. At the same time, there are interactions where native animation (or an entirely native view) will be your only way to make it smooth.

With such an approach, the application you create will be smoother and snappy. It will not only be pleasant for your users to use but also for you to debug and have fun with it while developing.


To sum up, nice and smooth animations can significantly influence the user experience and speed of your apps. If you would like to read more about the influence of animations on the user experience, check out this article.
