Complete source code of http:https://lichess.org, using Scala 2.10.1, Play 2.1, Akka 2, ReactiveMongo and Scalaz

This is full-stack application, not a library, and it may not be straightforward to get it fully running. I assume you run a Unix with mongodb.

Some steps of the installation will trigger a download of the galaxy. It will take ages.

git clone git:https://github.com/ornicar/lila
cd lila
git submodule update --init
bin/play compile

cp conf/application.conf.dist conf/application.conf

application.conf extends base.conf and can override any value. Note that application.conf is excluded from git index.

Launch the play console:

bin/play

From here you can now run the application (run). Open your web browser at localhost:9000.
