How can 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 securely using AsyncStorage. 4. Include the JWT in the Authorization header for protected routes.

What libraries do I need for handling JWT in React Native?

You can use libraries like jsonwebtoken for decoding and verifying JWTs, and axios for making HTTP requests. Additionally, @react-native-async-storage/async-storage is useful for storing the token.

How do I secure my API endpoints with JWT?

To secure your API endpoints, you should verify the JWT on the server side. Use middleware to check the token in the Authorization header and validate it before allowing access to protected routes.

Can you give me an example of a login function using JWT?

Sure! Here's a simple example:

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