How do I set up authentication in a React app?
To set up authentication in a React app, you can use libraries like Firebase, Auth0, or implement your own using JWT.
What is JWT and how does it work for authentication?
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 simple example of using Firebase for authentication?
Sure! First, install Firebase in your project. Then, initialize Firebase and use the signInWithEmailAndPassword
method for user login.
What about protecting routes in my React app?
You can protect routes by using a higher-order component or a custom hook that checks if the user is authenticated before rendering the component.
