async-storage VS react-native

AsyncStorage for data persistence

\[@RNC/AsyncStorage\]: NativeModule: AsyncStorage is null. To fix this issue try these steps: • Rebuild and restart the app. • Run the packager with \`--reset-cache\` flag. • If you are using CocoaPods on iOS, run \`pod install\` in the \`ios\` directory and then rebuild and re-run the app. • If this happens while testing with Jest, check out docs how to integrate AsyncStorage with it: https://react-native-async-storage.github.io/async-storage/docs/advanced/jest If none of these fix the issue, please open an issue on the Github repository: https://github.com/react-native-async-storage/async-storage/issues 5 | import { ReactQueryDevtools } from '@tanstack/react-query-devtools'; 6 | import { Platform } from 'react-native'; > 7 | import AsyncStorage from '@react-native-async-storage/async-storage';

You want this: react-native-async-storage

What do you mean by local storage? The browser based localStorage API does not exist by default in react-native. There is an analogue though... The most basic package that most people use, AsyncStorage is just a string based key-value store: https://github.com/react-native-async-storage/async-storage . It's very useful for anything simple. It also has a merge function which lets you automatically update stringified JSON objects without unpacking them and doing the modifications yourself.

Since the original React Native AsyncStorage was deprecated, you may be using the community solution: react-native-async-storage. I would personally recommend it!

I think that you using a deprecated package to store your state. Verify if you are using https://github.com/react-native-async-storage/async-storage.

React Native’s 2025 architecture introduces Fabric, TurboModules, and JSI for faster performance and smoother development. By removing the legacy bridge, it enables quicker rendering and efficient native integration. Developers benefit from improved tools, crash handling, and native module access. This upgrade makes React Native a robust, future-ready choice for mobile app development.

Introduction In 2025, startups face a critical decision when choosing their mobile development framework. The React Native vs Flutter debate continues to dominate discussions among entrepreneurs and developers alike. Both frameworks offer compelling advantages for cross-platform development, but which one truly serves startups better in today's competitive landscape?

Cross-platform development means writing code once and running it on multiple platforms like iOS and Android. This reduces time, cost, and effort compared to developing separate apps for each platform. Developers use frameworks to simplify this process, and two of the most popular are Flutter and React Native.

If you’re upgrading from React Native 0.79, it’s worth reviewing the RN 0.79 release notes before diving in.

The final RN 0.80 version comes with fresh React 19.1.0 (0e11e6a28b)! This brings improvements like "owner stacks" to help identify which component caused a specific error (although there's a known bug if you use the @babel/plugin-transform-function-name plugin).

This course was great for me because one, it was made within the last year (at the time I took the course anyway). It seemed anything older than this had out-of-date information (using an older version of React Native) and it would throw me off when I encountered something that wasn't done using the more recent versions of React Native/Expo.

Stricter Imports: With the introduction of "exports" in package.json (319ba0afd2, 9fc2a9b9e6), importing from internal folders (e.g., react-native/Libraries/...) may no longer work. Stick to official paths! Direct imports from react-native/virtualized-lists are now blocked (be8393c41b).
