How do I implement JWT authentication in my React Native app?

To implement JWT authentication in your React Native app, you can follow these steps: 1. Set up a backend server to issue JWTs. 2. Use a library like axios to make API calls. 3. Store the JWT in AsyncStorage after login. 4. Attach the JWT in the Authorization header for subsequent requests.

What library should I use to handle JWTs?

You can use libraries like jsonwebtoken for decoding and verifying JWTs, and axios for making HTTP requests.

How do I store the JWT securely?

You can store the JWT securely using AsyncStorage or SecureStore in React Native. SecureStore is recommended for sensitive data.

Can you show me a code example?

Sure! Here's a simple example:

import AsyncStorage from '@react-native-async-storage/async-storage';
import axios from 'axios';

const login = async (username, password) => {
  const response = await axios.post('https://yourapi.com/login', { username, password });
  const { token } = response.data;
  await AsyncStorage.setItem('jwt', token);
};

This code logs in a user and stores the JWT.
