react-native-fiesta VS MMKV

Some of the good ones I've found: https://github.com/mateoguzmana/react-native-fiesta (Uses Skia which is great, but animations themselves are a tad basic. But it's a super new project)

If you need complex animations or you want to animate something besides native components, Skia is your choice. Skia is a base rendering engine for Flutter and Chrome written in C++. React Native version provides access to Skia API using direct JSI calls, which makes it close to native performance with minimum overhead. As a result, you can build animations like this:

Source code

Recently, I did some improvements to react-native-fiesta, in order to use one of the latest versions of @shopify/react-native-skia. The improvements are very impressive!

In the following sections, we will see how to use react-native-fiesta to add some animated balloons into your application with some few lines of code.

react-native-mmkv is a wrapper around MMKV that allows you to easily implement secure storage in your app. It is arguably the fastest key-value storage for React Native apps

This library uses MMKV key-value storage and JSI to communicate between the JS side and the native side very quickly and synchronously. It is a suitable replacement for slow AsyncStorage. Follow this guide to migrate from AsyncStorage and get 30x faster on read and write operations in your app.

For those unfamiliar with MMKV, here's a link to their GitHub - https://github.com/Tencent/MMKV. Used in many mobile applications, such as Discord.

SWR library works great with React Native. By default, SWR library uses global cache store, but you will lose your cache when you reload your app. Here is a super-easy way to sync SWR cache with MMKV.

This library aims to provide a fast & reliable solution for you data storage needs in react-native apps. It uses MMKV by Tencent under the hood on Android and iOS both that is used by their WeChat app(more than 1 Billion users). Unlike other storage solutions for React Native, this library lets you store any kind of data type, in any number of database instances, with or without encryption in a very fast and efficient way.
