The driver for MongoDB is community-supported and is not supported by Cube or the vendor.




Add the following to a .env file in your Cube project:

# The MongoBI connector host. If using on local machine, it should be either `localhost` or ``:
# The default port of the MongoBI connector service
# MongoBI requires SSL connections, so set the following to `true`:

If you are connecting to a local MongoBI Connector, which is pointing to a local MongoDB instance, If MongoBI Connector and MongoDB are both running locally, then the above should work. To connect to a remote MongoDB instance, first configure mongosqld appropriately. See here for an example config file (opens in a new tab).

By default, MongoDB uses batching to build pre-aggregations.


No extra configuration is required to configure batching for MongoDB.

Export Bucket

MongoDB does not support export buckets.


To enable SSL-encrypted connections between Cube and MongoDB, set the CUBEJS_DB_SSL environment variable to true. For more information on how to configure custom certificates, please check out Enable SSL Connections to the Database.
