monger.core — com.novemberain/monger 3.5.0

Thin idiomatic wrapper around MongoDB Java client. monger.core includes fundamental functions that perform database/replica set connection, set default write concern, default database, performing commands and so on. Most of the functionality is in other monger.* namespaces, in particular monger.collection, monger.query and monger.gridfs

*mongodb-port* clj

*mongodb-write-concern* clj

admin-db clj

(admin-db conn)

Returns admin database

admin-db-name clj

command clj

(command database cmd)

Runs a database command (please check MongoDB documentation for the complete list of commands).

Ordering of keys in the command document may matter. Please use sorted maps instead of map literals, for example: (array-map :near 50 :test 430 :num 10)

For commonly used commands (distinct, count, map/reduce, etc), use monger.command and monger.collection functions such as /distinct, /count, /drop, /dropIndexes, and /mapReduce respectively.

connect clj

(connect)

(connect {:keys [host port uri] :or {host *mongodb-host* port *mongodb-port*}})

(connect server-address options)

(connect [server-address & more] options)

(connect server-address options credentials)

Connects to MongoDB. When used without arguments, connects to

Arguments: :host ("127.0.0.1" by default) :port (27017 by default)

connect-via-uri clj

(connect-via-uri uri-string)

Connects to MongoDB using a URI, returns the connection and database as a map with :conn and :db. Commonly used for PaaS-based applications, for example, running on Heroku. If username and password are provided, performs authentication.

connect-with-credentials clj

(connect-with-credentials credentials)

(connect-with-credentials hostname credentials)

(connect-with-credentials hostname port credentials)

Connect with provided credentials and default options

Countable clj protocol

count clj
