Compojure rest app and cookies

https://github.com/bakku/clj-rest-web-app

A session stores the currently logged in user ID, configured the ring-session middleware to use a cookie store. After restarting the server the session is refreshed as if it is not using any cookie store.

• configuring the cookie-store: https://github.com/bakku/clj-rest-web-app/blob/master/src/clj_rest_web_app/core.clj#L24
• setting the session after a successful login: https://github.com/bakku/clj-rest-web-app/blob/master/src/clj_rest_web_app/controllers/sessions.clj#L6
• running the application in docker, here I am setting the cookie secret: https://github.com/bakku/clj-rest-web-app/blob/master/docker-compose.yml#L15

By default Ring uses an in-memory session store. you can change it to store data in a cookie or something persistent like Redis

Its configured it to store the data in a cookie
using the site-defaults from ring which already wrapped my routes using the session middleware but the site-defaults are using the in-memory session. I had to update the session configuration of the site-defaults according to my needs to get it to work

Start by reading the session middleware configuration in src/clj_rest_web_app/core.clj and the session update in src/clj_rest_web_app/controllers/sessions.clj. Check docker-compose.yml for the cookie secret and compare the site-defaults session configuration with the Ring session-store guidance. Done means the logged-in user session remains available after restarting the application.
