1. Hot update

React Native official website solution

  • Reactnative. Cn/docs/more – r…

App Center is a hot update service provided by Microsoft. Hot updates allow you to bypass the AppStore’s approval process and modify existing apps directly. For domestic users, we also recommend the Pushy hot update service provided by this website. Compared with CodePush, it provides all-Chinese documents and technical support, and the server deployment is faster in China. It also provides automatic differential update mode, greatly saving update traffic

2. Local storage

  • Permanent storage, data will not be cleared after closing the APP
  • If you uninstall the APP directly, the data will not be cleared. You need to manually clear the data or log out of the APP

AsyncStorage

  • Have been abandonedPlease use one of these insteadCommunity software package.

AsyncStorage is an unencrypted, asynchronous, persistent, key-value storage system that is global to applications. It should be used instead of LocalStorage.

It is recommended that you use abstract AsyncStorage at the top rather than AsyncStorage directly for lightweight purposes, since it runs globally.

On iOS, AsyncStorage is supported by native code that stores small values in serialized dictionaries and large values in separate files. On Android, AsyncStorage will use RocksDB or SQLite depending on what is available.
