How do I set up authentication in a Node.js frontend?

To set up authentication in a Node.js frontend, you can use libraries like Passport.js or JWT for token-based authentication.

Can you explain how to implement JWT for authentication?

Sure! First, install the jsonwebtoken package. Then, create a token when the user logs in and send it to the client.

What about securing API routes?

You can secure API routes by verifying the JWT in your middleware. This ensures that only authenticated users can access certain endpoints.

Are there any best practices for handling user sessions?

Yes, always store tokens securely, use HTTPS, and consider implementing token expiration and refresh tokens.
