immutant-fressian

Adds a :fressian codec option to immutant. Works out of the box with messaging and caches.

Author: Ian Eslick

Usage

In project.clj

(:dependencies [immutant-fressian "0.2.0"])

Require immutant-fressian.core in your immutant init.clj

(require [immutant-fressian.core :as ifr])

Loading that namespace extends the Immutant codecs and the messaging multimethods. Anywhere in your code after the extension is required...

(msg/publish "/queue/test" {:test "This is my test object"}
             :encoding :fressian)

(cache/create "test" :mode :local
                     :persist true
                     :encoding :fressian)

immutant-fressian is built on the fressian-clojure library which wraps the Java Fressian API and provides hooks for registering one or more handlers for your own data types. The best place to add hooks is a namespace required in your init.clj file or in that file directly.

You can follow the included example of fressian-encoding Datomic Entities and Database values in entity.clj:

(require [immutant-fressian.entity :as ifre])

(ifre/set-datomic-connection <connection>)
(ifre/add-datomic-handlers)

(msg/public "/queue/test" [(d/db <conn>) (d/entity (d/db <conn>) <id>)]
            :encoding :fressian)
