neo4j-clj.core — gorillalabs/neo4j-clj 1.1.0

This namespace contains the logic to connect to Neo4j instances, create and run queries as well as creating an in-memory database for testing.

config clj

(config options)

connect clj

(connect url)

(connect url options)

(connect url user password)

(connect url user password options)

Returns a connection map from an url. Uses BOLT as the only communication protocol.

You can connect using a url or a url, user, password combination. Either way, you can optioninally pass a map of options:

:logging - a Neo4j logging configuration, e.g. (ConsoleLogging. Level/FINEST)

create-in-memory-connection clj

(create-in-memory-connection)

To make the local db visible under the same interface/map as remote databases, we connect to the local url. To be able to shutdown the local db, we merge a destroy function into the map that can be called after testing.

All data will be wiped after shutting down the db!

create-query clj

(create-query cypher)

Convenience function. Takes a cypher query as input, returns a function that takes a session (and parameter as a map, optionally) and return the query result as a map.

defquery clj macro

(defquery name query)

Shortcut macro to define a named query.

disconnect clj

(disconnect db)

execute clj

(execute sess query)

(execute sess query params)

get-session clj

(get-session connection)

get-transaction clj

(get-transaction session)

retry-times clj

(retry-times times body)

with-retry clj macro

(with-retry [connection tx & {:keys [max-times] :or {max-times 1000}}] & body)

with-transaction clj macro

(with-transaction connection tx & body)
