Maven Javadocs

See the documentation

Build manually

To benefit from the latest improvements and fixes, you may want to compile ReactiveMongo from source. You will need a Git client and SBT.

From the shell, first checkout the source:

$ git clone

Then go to the ReactiveMongo directory and launch the SBT build console:

$ cd ReactiveMongo
$ sbt
> +publishLocal

Running tests:

In order to execute the unit and integration tests, SBT can be used as follows.

sbt testOnly

The test environement must be able to handle the maximum number of incoming connection for the MongoDB instance. This must be checked, and eventually updated, using ulimit -n.

CircleCI Test coverage

Reproduce CI build:

To reproduce a CI build, see the Docker tools.
