How do I set up JWT authentication in React Native?

To set up JWT authentication in React Native, you'll need to follow these steps: 1. Install necessary libraries like axios and jwt-decode. 2. Create a login form to collect user credentials. 3. Send a POST request to your backend API to authenticate the user and receive a JWT. 4. Store the JWT securely using AsyncStorage. 5. Use the JWT for subsequent API requests by including it in the Authorization header.

What libraries do I need to install?

You will need to install axios for making HTTP requests and jwt-decode for decoding the JWT. You can install them using npm or yarn: npm install axios jwt-decode.

How do I store the JWT securely?

You can use AsyncStorage to store the JWT securely. Here's a simple example: await AsyncStorage.setItem('token', jwt); and to retrieve it, use const token = await AsyncStorage.getItem('token');.

Can I use JWT with other authentication methods?

Yes, JWT can be used alongside other authentication methods like OAuth or traditional session-based authentication. It provides flexibility in managing user sessions.
