How do I set up JWT authentication in a Rails API?

To set up JWT authentication in a Rails API, you can use the 'jwt' gem. First, add it to your Gemfile and run bundle install.

What are the steps after installing the gem?

After installing the gem, you'll need to create a method to encode and decode the tokens, and set up your user model to handle authentication.

Can you show me an example of encoding a token?

Sure! You can use JWT.encode(payload, secret_key) to encode a token, where payload contains user data and secret_key is your application's secret.

How do I handle token expiration?

You can include an expiration time in your payload, and check it when decoding the token to ensure it's still valid.
