macchiato.middleware.flash

Middleware that adds session-based flash store that persists only to the
next request in the same session.

flash-request

(flash-request request)

Adds :flash key to request from :_flash in session.

flash-response

(flash-response response request)

If response has a :flash key, saves it in :_flash of session for next
request.

wrap-flash

(wrap-flash handler)

If a :flash key is set on the response by the handler, a :flash key with
the same value will be set on the next request that shares the same session.
This is useful for small messages that persist across redirects.
