react-native-biometrics VS react-native-reanimated

react-native-biometrics helps us to access functionalities like FaceID, TouchID, or any other biometric features that are available in the device. react-native-biometrics uses the device Keystore for biometric authentication. it's helpful when you develop an application that is security intensive.

In React Native, this solution is readily available with the react-native-biometrics library, which is, unfortunately, not actively maintained (last commit 2/2020) and its biometrics part does not support the latest standards, such as fallback to passcode when Face ID fails.

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.
