How to associate data with an API session?

[notramo]

I want to provide different data on given routes, based on parameters provided at login time. How to persist this data to the session?

It seems like it's possible to accomplish this functionality by putting the data into the JWT token, but is there an idiomatic way to access it inside controller/templates?

There's a Lucky shard that lets you store session in redis, otherwise you're at the mercy of cookie limits with normal sessions. But provided your data doesn't get too crazy, just use session.set(:data, jwt)

How to add a field to the JWT token? E.g. I want to add a scope field next to the user_id.

Assuming you're using the UserToken for all this, you can just do that here...

https://github.com/luckyframework/lucky_cli/blob/7c3c69c775ba9aad7ac0206c052db66a906941c1/src/api_authentication_app_skeleton/src/models/user_token.cr#L7

payload = {"user_id" => user.id, "scope" => "something"}

Does it mean that I have to patch the current implementation?
Then how can I get the value? Do I have to patch that too? Or is there a way to get a field from the token?

I'm having to make a lot of assumptions here since I don't have any of your code... but assuming you're using the UserToken class, then it's just in your src/models/user_token.cr file. Just open that file and make whatever changes you need to.
