React Native Authentication Asyncstorage - TypeScript - 2023
All of React Native Templates have support for saving the user login credentials. This means that when users open the app, they are automatically logged in if they previously entered their valid login info. To achieve this behavior, we are leveraging AsyncStorage. In this tutorial, we are offering a React Native AsyncStorage example, inspired by our work on React Native starter kits, including functional source code and step by step explanations.
So what is AsyncStorage in React Native apps? Before we learn about AsyncStorage, let us consider an example of an AsyncStorage use case, to make it easier to understand. You might have seen that many applications offer login using Login ID or Password or any other way like Facebook, Twitter, Google, etc. So when you log in for the first time in the app, you type in the login credentials manually. Then after you close the app and come back again, you don’t need to log in again. Under the hood, in React Native, your credentials were retrieved from AsyncStorage to log you back into the app.
AsyncStorage is a key-value, asynchronous, simple, persistent, unencrypted, storage system that is global to the app. It is used as a LocalStorage in Apps similar to localstorage in browser. It is very useful for the variables you want to use globally in the app.
