How can I implement API authentication in a React Native app?

You can implement API authentication in a React Native app using libraries like Axios for HTTP requests and JWT for token management.

What is JWT and how does it work?

JWT, or JSON Web Token, is a compact, URL-safe means of representing claims to be transferred between two parties. It allows you to verify the token's authenticity and the user's identity.

Can you show me a code example for using JWT in React Native?

Sure! Here's a simple example:

import axios from 'axios';

const login = async (username, password) => {
  const response = await axios.post('https://yourapi.com/login', { username, password });
  const token = response.data.token;
  // Store the token for future requests
};

This code sends a login request and stores the JWT for future use.

What should I do if the token expires?

You should implement a refresh token mechanism to obtain a new token without requiring the user to log in again.
