How to use custom session store

[JaceEgg]

Does anyone have an example of how to inject your own implementation of ring.middleware.session.store? I wanted to try implementing one using XTDB, but couldn't quite figure out how to wire it up without copy/pasting and altering wrap-session:

biff/src/com/biffweb/impl/middleware.clj

Line 115 in edfd869

(defn wrap-session [handler]

First you'll need to remove this line from your config.edn file:

biff/starter/resources/config.edn

Line 18 in edfd869

:biff.middleware/cookie-secret #biff/secret COOKIE_SECRET

Then you can create a use-xtdb-session-store biff component that adds a :biff.middleware/session-store key to the system map. It'll need to go after the use-xtdb component (

biff/starter/src/com/example.clj

Line 66 in edfd869

biff/use-xtdb

) but before the use-jetty component. use-jetty merges the system map into incoming requests, so that's how wrap-session gets access to it.

The component would look something like this:

(defn use-xtdb-session-store [{:keys [biff.xtdb/node] :as ctx}]
  (assoc ctx :biff.middleware/session-store ...))

By the way, when you have that working, if you stick the code in a gist or something I'll put a link to it in the content library. I bet there are others who would be interested in that.

Thanks for the instructions. Here is what I came up with: https://gist.github.com/JaceEgg/a4150b8f360110d1cb56a5744aeca4d4
Feel free to make changes to it if you put it in the content library, I am not very familiar with clojure.

Looks great! I just added a link here.
