An example of an AI chatbot conversation about implementing JWT authentication in Rails.
How can I implement JWT authentication in a Rails application?
To implement JWT authentication in Rails, 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, set up your user model, and create a controller for handling authentication.
Can you show me an example of encoding a token?
Sure! You can encode a token like this: JWT.encode(payload, Rails.application.secrets.secret_key_base) where payload contains user information.
How do I handle token expiration?
You can set an expiration time in your payload, and then check it when decoding the token to ensure it's still valid.
