Monger, a modern Clojure MongoDB Driver

Monger is an idiomatic Clojure MongoDB driver for a more civilized age.

It has batteries included, offers powerful expressive query DSL, strives to support modern MongoDB features and have the "look and feel" and flexibility of the MongoDB shell.

Monger is built from for modern Clojure versions and sits on top of the official MongoDB Java driver.

Project Goals

There is one MongoDB client for Clojure that has been around since 2009. So, why create another one? Monger authors wanted a client that would

Support most of modern MongoDB features, focus on those that really matter.
Be well documented.
Be well tested.
Target modern Clojure versions.
Be as close to the Mongo shell query language as practical
Integrate with libraries like Joda Time, Cheshire, clojure.data.json, Ragtime.
Support URI connections to be friendly to Heroku and other PaaS providers.
Not carry technical debt from 2009 forever.
Integrate usage of JavaScript files and ClojureScript (as soon as the compiler gets artifact it is possible to depend on for easy embedding).

Project Maturity

Monger is not a young project: started in July 2011, it is over 7 years old with active production use from week 1.

Continuous Integration Status

Monger Is a ClojureWerkz Project

Monger is part of the group of Clojure libraries known as ClojureWerkz, together with Cassaforte, Langohr, Elastisch, Quartzite and several others.

Development

Monger uses Leiningen 2. Make sure you have it installed and then run tests against supported Clojure versions using

./bin/ci/before_script.sh
lein all do clean, javac, test

Or, if you don't have mongodb installed, you can use docker

docker-compose up
./bin/ci/before_script_docker.sh
lein all do clean, javac, test

Then create a branch and make your changes on it. Once you are done with your changes and all tests pass, submit a pull request on Github.
