react-native-reanimated VS lottie

Supports Animation: Tamagui leverages the popular open-source library — Moti as a reanimated driver for animation libraries such as react-native-reanimated and React Native Animated.

FYI react-native-reanimated (https://github.com/software-mansion/react-native-reanimated) is not the Animated API from React Native. react-native-reanimated allows JS code to run on a UI thread that is able to synchronously modify layout, providing alternative synchronous ways for you to hook into the layouting. For instance, as opposed to the asynchronous `measure()` method provided by React Native to measure layouts, react-native-reanimated allows one to call their version of `measure()` (https://docs.swmansion.com/react-native-reanimated/docs/api/...) to perform the same operation on the UI thread, synchronously.

By using libraries like Reanimated, React Native MMKV, and React Native Skia, you leverage the native thread. However, I know there are developers building amazing things who think outside the box. I'm always thrilled when I read engineering blogs from companies like Netflix, Meta, and Shopify. They create solutions beyond the limits.

Currently having issues with reanimated (expo installs 2.14.4). My app will crash randomly – possibly linked to these issues here and here.

Reanimated is probably what you're looking for. https://docs.swmansion.com/react-native-reanimated/

One of is: https://github.com/software-mansion/react-native-reanimated/issues/2327

use third party lib that is a beast, but will require a lot of work and upfront knowledge (https://docs.swmansion.com/react-native-reanimated/)

Catalin Miron is also good. Reanimated 2 animations are still relevant. I also would suggest reading the reanimated docs here. That's how I find my way around.

Actually, that's not entirely accurate. The lottie-web library itself doesn't support rendering to WebGL. However, there is a package called canvaskit-wasm that wraps Skia (a graphics engine) with WebAssembly (wasm). This package includes a module called skottie which supports rendering animations into a WebGL surface. However, there is a drawback with this approach: using wasm requires loading a relatively large package, and it's uncertain whether all features are supported correctly, as the official compatibility table that tracks lottie support on different platforms does not include skottie.

Time has passed, though. React Native Animatable is still a good solution today, but it’s not as performant nor configurable as the more modern options. Nowadays, there are several new ways to animate views more efficiently in React Native. Between the good-old React Native animated API, Reanimated/Reanimated 2, Moti (which can almost be a drop-in replacement for React Native Animatable), and Lottie, adding silk-smooth native animations to a React Native app has never been easier.

According to the supported features and the forums, it's not supported. You might want to ask the creators via GitHub.

HereHere you can find the supported AE features by the Lottie library. The only other variants would be as GIF, which is technically outdated and needs a large file size for a good resolution, or as video, e.g. as webm or h.265 if transparency is needed, but this is not supported by all browsers and may also need a rather large file size. My advice is to optimise/modify the AE animation for Lottie.
