UI Animations with Lottie and After Effects

By: Mireia Alegre Ruiz, Emilio Rodriguez Martinez

Overview of this book

Lottie is a small and scalable JSON-based animation file. LottieFiles is the platform where Lottie animations can be uploaded, tested, and shared. By combining the LottieFiles plugin and the LottieFiles platform, you’ll be able to create stunning animations that are easy to integrate in any device. You’ll also see how to use the Bodymovin plugin in After Effects to export your animation to a JSON file. The book starts by giving you an overview of Lottie and LottieFiles. As you keep reading, you’ll understand the entire Lottie ecosystem and get hands-on with classic 2D animation principles. You’ll also get a step-by-step guided tour to ideate, sketch for storytelling, design an icon that will fulfill the needs and expectations of users based on UX, and finally animate it in Adobe After Effects. This will help you get familiar with the After Effects environment, work with vector shape layers, create and modify keyframes using layer properties, explore path and mask features, and adjust timing easily to create professional-looking animations. By the end of this animation book, you’ll be able to create and export your own Lottie animations using After Effects and implement them in mobile apps using React Native. You’ll also have an understanding of 2D animation best practices and principles that you can apply in your own projects.

Chapter 9: Let’s Do Some Magic: Integrating Your First Lottie Animation

Our app is now ready to display Lottie animations on its screens. In this chapter, we will learn how to integrate a Lottie file, whether downloaded from https://lottiefiles.com/ or generated by us in Adobe After Effects (AE). The requirements to perform this integration successfully are as follows:

  • Have a JSON file with the Lottie animation exported from AE using the Bodymovin plugin or downloaded from LottieFiles.
  • Have the React Native project ready after having followed the steps described in Chapter 8, Installing lottie-react-native.

The final result will be our app displaying the provided Lottie animation on the initial screen. The topics we will cover in this chapter are as follows:

  • Understanding the Lottie file
  • Using a Lottie file in a React Native app
  • Using lottie-react-native in your TypeScript app
  • Finding documentation for lottie-react-native
  • Using remote...
