How can I implement authentication in my React app using React Query and Axios?

You can use React Query to manage your server state and Axios for making HTTP requests. First, set up your Axios instance with the base URL of your API.

What about handling login and storing tokens?

For login, create a mutation using useMutation from React Query. On success, store the token in local storage or context.

How do I protect routes in my app?

You can create a higher-order component or a custom hook that checks for the token in local storage and redirects if it's not present.

Can you show me a code example?

Sure! Here's a simple example of a login mutation:

const loginMutation = useMutation(loginUser, {
  onSuccess: (data) => {
    localStorage.setItem('token', data.token);
  },
});
