How can I implement authentication in my Express API?
An example of an AI chatbot conversation about implementing authentication in an Express API.
How can I implement authentication in my Express API?
You can implement authentication in your Express API using middleware like Passport.js or by using JWT (JSON Web Tokens). Which method are you interested in?
I'm interested in using JWT. Can you guide me through the steps?
Sure! First, you'll need to install the jsonwebtoken package. Then, create a login route that generates a token upon successful authentication.
What should I include in the token?
Typically, you should include the user's ID and any other relevant information. Make sure to sign the token with a secret key.
How do I protect my routes with the token?
You can create a middleware function that verifies the token on protected routes. If the token is valid, the request proceeds; otherwise, it returns an error.
